The average national cost of adding a room or building an addition is $42,639, with most homeowners spending between $20,963 and $65,796. This data is based on actual project costs as reported by HomeAdvisor members.

Many homeowners eventually come to that daunting dilemma: whether to buy their dream house or transform their current home into that dream. Once you make the commitment to build an addition, you've probably decided to go down the latter road. This decision might be something you've long considered, or it may have been thrust upon you by an expanding family. In either case, recognize that this will be a profound investment in time and money, but one that, if done properly, will enhance the value of your most important investment: your home.

You can choose from several types of additions for an average house, including ground level additions, second floor additions and detached additions. Each option has its own benefits, drawbacks and estimated prices based on factors such as the size of the structure and the features that you want to incorporate.

An extra room means exactly that. Homeowners who choose this type of an addition often do so to add a family room, bedroom or multiple spaces. When you want to add an additional room to your home, you typically have two options: build out or build up.

This is a major construction project that involves creating an additional building structure and integrating it with the rest of the home. Average costs run anywhere from $80 to $200 per square foot. No matter whether you build out or up, you should:

Building out typically involves adding a room at ground level, which is one of the most popular types of additions. These options increase the footprint of your home by extending the houses perimeter outward, which offers minimal disruption to the rest of the home. Potential drawbacks of building out include the cost of having to pour a new foundation, the loss of yard or property space and the possibility that you may need to get a zoning variance depending on local regulations.

If you want to expand your living space without increasing the footprint of your home, building up is a great option. For this type of addition, you add a room to the second story, or you could add an entire second story onto a one story home. Even though your contractor won't need to create a new foundation, he may need to strengthen the existing foundation to support the extra weight. On the downside, you need to check your town's rules to make sure you're not limited in the height of your home. Additionally, you'll need to add a staircase, which typically uses up 80 to 120 square feet of living space.

Sunrooms offer a budget-friendly alternative to a traditional house addition. Average costs run anywhere from $16,315 for the average sunroom, up to $70,000 or more for a 200-square foot addition with footings and a slab foundation. The cost of this project depends on the amount of space it adds, the location of the sunroom, extras such as electrical wiring and whether the room is heated (four-season room) or not heated (three-season room). Other considerations include hiring:

Buying a prefabricated sunroom runs around $11,000 per 150 square feet. Once you factor in adding heat, electricity and all the construction costs, it's not unusual to pay between $300 and $400 per square foot for the finished product. If you want to keep the costs low, consider adding the sunroom as a three-season room without heating.

Before you decide on a sunroom, get a few estimates to make sure youre getting the most competitive prices. Meet with a professional who can help assess the space, take accurate measurements and recommend the finishes and construction methods that will work best for you, your property and your climate.

Detached additions can range in style and price, with prefabricated, simple shed-like rooms running around $15,000 without electricity or heat, or full guesthouses that share similar costs as a detached garage addition, which run around $24,658 on average. Like the other types of additions, youll need a contractor to help install and finish your detached addition. Youll also need an electrician to add the necessary wiring and painters to finish the walls.

As with any other addition, the materials you choose have a direct impact on the cost of this project. Consider the following:

Return to Top

When youre planning your budget for this project, you need to consider many different factors, including the square footage and the size of the addition. The larger you go, the more expensive the project will be. Other important factors include necessary services, including:

Return to Top

The answer to this depends on the complexity of the addition. If youre adding a simple family room onto your home with one door into the rest of the house and one to the outside, a contractor should be able to handle it without the help of an architect. If you're moving walls, redesigning the way one room flows into another, adding a half loft and a spiral staircase or planning countless other complicated or intricate changes to your existing home, you may want to consider bringing an architect on board.

An architect will certainly add to your upfront costs on the project, but consider that a professional engineer can take your ideas and build them into something even more amazing. Also, by adding more clarity to your vision before construction starts, cost estimates will hit closer to the mark. When the project is done in partnership with an architect, you're also more likely to wind up with something that boosts your homes value.

Return to Top

Even if you have no plans to sell anytime soon, consider the resale value of your project. You might not always turn a profit on your home-expansion investment, but you should go into the job with realistic expectations about at least some kind of payback.

Because they're among the most expensive home projects, additions sometimes return less on your investment than remodels. If you're significantly adding to the square footage of your home or adding important types of rooms, such as bedrooms and bathrooms, your investment may pay off considerably.

Return to Top

Get everything in writing. First, agree on a total amount before discussing anything further.

It's reasonable for contractors to expect some money in advance, and then again after specific milestones during the course of the project. Be aware that shelling out too much money could put you at risk, and giving too little could put your contractor at risk. It's a delicate dance, but one that should be precisely choreographed before anybody fires up the power tools.

Still, no matter how detailed your plan is, remember that things happen. Find out about your contractor's change-order policy. Once you see your addition come to life, you may change your mind about the colors, fixtures or even the layout of the room. You may find that the contractor didn't understand your plan and made some decisions that didn't square with what you'd intended. Or, the addition may run into problems that neither you nor the contractor could have foreseen. Each of these could have enormous effects on the cost of the project, and each can cause friction with your contractor. Minimize the conflicts by spelling out, as clearly as possible on the front end, how each of these contingencies would be handled.

#1 Will the addition add value to my home?

Adding on to your home is among the priciest projects that you can undertake as a homeowner. Experts suggest that you can expect to see a return on your investment of:

#2 Will an addition look like it was tacked on?

Without the services of a designer or an architect, you could be left with an addition that looks like an afterthought or an obvious add-on feature. Skilled designers can create the space you want and deftly tie it into the existing structure so that it looks like it was always there.

#3 Do I need to worry about restrictions?

Always check with your local government to research zoning restrictions. In some areas, you may not be able to build within a certain number of feet of the front, sides or rear of the property lines. Other areas have rules about how much space on your property can be covered with buildings, how close you can get to protected spaces such as wetlands or how high you can build up.

#4 What should I look for in a contractor or a remodeling company?

Verify that the pros are licensed and insured. Check references and ask for pictures of their prior work. Ask the pros how long they've been doing this work, how they screen subcontractors and how long they expect the project to take. Get estimates from at least two or three contractors to get the most competitive prices and find the one that's going to work best for you.

#5 What should my first step be?

Create a plan for your new room, find a contractor to do the work and get all the necessary permits. This kind of a major project requires local permits to make sure the work is done according to building codes.

Return to Top

Adding on to a house is a very expensive project, but there are ways to shave money off your budget. For example, in some cases you may be able to remodel instead of add on. Maybe you could finish the basement (average cost $2,852) to provide an extra bedroom with a bathroom or a living space. Increasing the efficiency of your space can make an expansion unnecessary. For example, adding 200 square feet of space onto a kitchen could cost anywhere from $48,000 to $95,000. Swapping your old cabinets out for better-organized, custom cabinets costs around $35,000, but it might be all you need, which saves $13,000 to $60,000.

Other money-saving options include using detached additions instead of attached ones. A prefabricated detached structure could cost less than $20,000, and it could be used as a guesthouse or an office to provide the extra space that you want. Often, building up also saves money by avoiding excavation costs and the need for pouring a new foundation.

Lastly, consider how handy you might be. Tackle any DIY projects such as laying flooring, painting the walls or installing a new vanity on your own instead of paying a contractor to the work. Doing your own demolition, for example, can save you more than $500 in labor charges.

It's easy to find a list of builders for your project, what's not so easy is getting true apples to apples estimates from them. Without using a proven system to make estimate comparisons accurate, we know for a fact that your prices will vary greatly between each contractor! How do we know this? We learned the ins and outs of addition building beforewe setup thissurprisinglyuseful website.

Look, when you're spending $50,000 or $250,000 on a home addition, don't you think a building guide for $19.95 made by an award winning website, which was built by home addition builders, could save you from a couple of headaches and probably a fewthousand dollars?

Our guideis perfect for busy people who don't have the time to go back and fourth on the phone with multiple contractors toget each contractors estimate to compare fairly against each other. It's really simple to use because the information is not rocket science, but sometimes it's the no brainer details that make all the difference in life.

The truth is that any good contractor can provide you with this type of information, but none of them will simply because they want your business. They won't make any money from you by spending time teaching you how they get apples to apples estimates from their subcontractors. We know this for a fact because we were in the business of remodeling prior to focusing on the site alone.

Liberty Industries has been in the contamination control industry a LONG time, and they have MANY resources available at a range of prices to make sure your laboratory or specialized manufacturing area is top drawer. Some of these materials would be good to give to ALL personnel who are involved and, of course, especially all managers responsible for proper cleanroom cleaning procedures, regardless of your cleanroom classification.

So, as just one of the many cleanroom supplies you and your staff utilize, consider the following, described in greater detail at Libertys website, http://www.liberty-ind.com:

There is a WORLD of information in existence on everything from processes for cleanroom packaging to how to store and suit-up in cleanroom gowns to all the various steps to keep every square millimeter of your area within the required specswhich are many: ISO 3, ISO 5, ISO 7, ASHP, USP 797, SUP 797, Joint Association of Hospitals and NARD recommendations for risk level III sterile compounding, etc. However, here are just a few of the tips that may be of help:

Standard air flow

A conventional room is enclosed, has incoming air that is both conditioned and filtered to create a positive pressure within the room. This air comes in via ceiling diffusers and exhausts through the wall-mounted registers which is the air return to the A/C system. Under the specs of Federal Standard 209C, this room could produce a Class 100,000 environment, assuming personnel entering it maintain proper cleanroom attire, appropriate contamination control equipment is utilized, and there is a regular maintenance and cleaning procedure done to eliminate contamination which enters or is produced inside the cleanroom.

Non-unidirectional, semi-turbulent airflow

This type of enclosed, clean area also has air that is both conditioned and filtered, where the air comes in via a ceiling plenum. At that point, the air is diffused throughout the room by way of many slots in the flow-thru ceiling tiles. Then the air is pushed vertically at low velocities, and exhausts near or at the level of the floor. As with the conventional cleanroom, this style is able to make a Class 100,000 atmosphere to the specifications of Federal Standard 209C, and it also requires rigid personnel control, high-quality, specialized equipment, and a cleaning routine consistent with maintaining that level of cleanliness.

Non-turbulent airflow

This kind of enclosed, controlled environment has the treated air enter through a HEPA filter wall. The horizontal air velocity is 72-108 feet per minute (FPM) and its exhausted through an air return on the opposite wall. The design works for several class cleanrooms per Federal Standard 209C: Class 1, 10 or 100, with regard to the air upstream from the work area as, naturally, the air downstram depends on how contaminating the workstation is, though should exit via the return air wall. Finally, this room, as with all others, must be subject to rigid cleanroom techniques of the personnel, as well as a routine, diligent cleaning program.

Vertical, unidirectional airflow

This enclosed cleanroom design has the conditioned air enter by way of a HEPA filter ceiling. The filtered air moves straight downward at 72-108FPM as the design above, but the air is then exhausted via a grate system in the floor. Further, like the prior unit, it, too, can produce a Class 1, 10 or 100 atmosphere per Federal Standard 209C upstream from the work bench.

THIS design is generally thought to be the one to use for the optimum clean room but requires VERY stringent cleaning techniques, done continually as part of the operating process, in addition to specialized cleaning performed for each area in the cleanroom.

Particle numbers by class:

Max. no. of particles/ft > 0.5 and larger Class Max. no. of particles/ft > 5.0 and larger

Below is a helpful chart from Liberty regarding the appropriateness of which class cleanroom to what kind of air flow, in light of the material presented above.

Air cleanliness classes guidelines

Cleanroom with wall-to-floor airflow

Cleanroom with wall-to-wall airflow

Cleanroom with ceiling-to-floor airflow

Cleanroom with wall-to-open-end airflow

Cleanroom with non-unidirectional, turbulent airflow

In certain industries, performance is COMPROMISED when certain types of particulate is in the work environment. Examples are:

Many procedures have microminiature devices which are often found to be at risk with impurities such as dust, dirt, lint, skin cells, etc. of about .3 microns, as well as with the occurrence of temperature, humidity, static, etc. fluctuations. As a result, the cleanroom has evolved for both environmental and contamination control.

Your CLEAN ROOM, therefore, is an important factor to your facility regarding economic:

This can also include a dust-free enclosure, environmental chamber for testing (e.g. temperature, humidity, altitude, vibration, stability, etc.), specialty workstations, laminar flow tunnels, workstations, hoods, air showers, and the like. In all of those, rigid control is needed for optimal results. Therefore, technicians in anything considered a white room must be specially trained to regularly perform the right processes and in the right order.

Major sources for complications are:

According to the Austin Contamination Index (Encyclopedia of Clean Rooms, Bio-Cleanrooms and Aseptic Areas), heres what the typical tech generates in a room, even when fully-clothed and in appropriate cleanroom garments:

Particles given off/worker/minute by activity (.3 microns or larger)

To get the maximum performance from your cleanroom, the following should be considered a framework of parameters to obtain the specs YOUR process requires:

One of the most particulating factor in a controlled environment is the PERSONtheir clothing, shoes, hair, skin, etc.which emphasizes the need for stable, high-quality, specialized garments to achieve the cleanroom level your room requires. Appropriate wearability means that the garment resists breakdown and emits little to no particles, such as lint.

Synthetic materials are ideal for a clean environment because:

When choosing a quality source of clothing for lab techs to wear, here are some decision parameters regarding synthetic, low-linting or lint-free fabrics:

1. FROCKS, LAB COATS AND COVERALLS. Whether you decide on a lab coat or coverall thats disposable, or washable and re-usable, be sure to choose a simple design thats especially snug-fitting at the neck. Collars, pockets, darts, belts, pleats, and the like both retain and generate lint. Also, elastic around openings is key to a close fit. For the ultimate in cleanroom cleanliness, a coverall (sometimes called an overall or bunny suit) should be selected. The coveralls hood needs to be INSIDE the coverall so that particulate (e.g. hair, skin cells, and lint) falls into the coverall. Furthermore, the legs should be tucked into the cleanroom boots, boot covers or shoe covers so that all particulate is captured and doesnt get out to contaminate the cleanroom.

A frock is sometimes permitted in certain cleanrooms, but be aware that the downside of a frock is that the bottom is open which enables materials to fall to the floor. As a result, with the various activities by cleanroom personnel, that particulate is easily swirled up in air movement into the clean environment.

2. BOUFFANT CAPS AND HOODS. An important part of a critically clean environment, contamination control from the head must be addressed. A hood covers the head, neck, and ears and is tucked into the lab coat, frock, or coverall to catch slough from escaping. They fit snugly to cover all but the face (sometimes the eyebrows), utilizing elastic, snaps, and various sizes to fit well.

Some applications are suitable to using bouffant caps, which are typically made of cellulose, polypro, polyolefin, and Tyvek and are intended to limit particulating from head hair. Having similar limitations as a surgeons cap, they can cover the ears to some degree but note that gaps can allow dandruff, and other particles to fall to cleanroom work surfaces and floor.

3. FACE SHIELDS, MASKS, BEARD GUARDS, MOUSTACHE COVERS, ETC. Just as with other cleanroom garments, these items may also be necessary for your procedures. Certain lab operations require such materials around your laminar flow workstationsvertical flow, horizontal flow or cross flow, vertical fume hoods, biohoods, air curtains, and other cleanroom equipment. The same concepts apply: eliminate and contain any and all particulates.

4. FOOT COVERINGS. Because technical lab personnel may walk from a dirty parking lot with rain, mud or snow, then perhaps through a dusty manufacturing areainto your cleanrooms gowning area. Though they may use a shoe cleaning machine, no shoe cleaner can remove all contamination and no shoe bootie can completely capture dirt, dust or lint. As a result, your controlled area will degrade from a clean, ambient atmosphere to one battling contamination. This is why management of foot-borne particles is critical to maintaining your required cleanroom standards.

5. GLOVES AND HAND CARE. Hands introduce many complications to critical area, e.g. perspiration and skin oils, skin lotions, hair spray, fingernail polish and other cosmetics. Because technical workers have constant contact with your operations products, tools and equipment, the cleanroom facilities managers must not only establish and maintain strict procedures, they must choose gloves appropriate to the laboratory scenarios. Non-porous gloves become uncomfortable fairly quickly, yet perspiration can bleed through fabric, as well as through garment seams. Rubber gloves contain free sulphur and can cause chemical contamination. Be aware of such considerations when selecting the hand coverings for your personnel.

6. WIPES. Sometimes referred to as wipers, wiping cloths come in a wide variety of shapes, sizes and materials. The problem is: the more non-particulating the wipe, the less its ability to absorb or pick up liquids and particulate! They can actually SPREAD oil, grease, etc. rather than collect them. So, talk in detail with your representative at Midstates Marketing for help in determining whats best for your operation.

Reusable garments, sometimes called washable garments, can be a cost saver as compared to disposable garments, depending on the usage of the clean room. Just as a baby diaper service leaves a new supply when picking up the items needing laundering, a cleanroom laundry can provide that same convenience, whether its internal or external to your facility. However, a specialty laundry does not just offer garments that are free from dirt and spots, they give your contamination control staff clean, ready-to-wear cleanroom garments that are free of lint, dust and other particles, and all other types of contamination.

Laundry services giving super clean garments:

Naturally garments used in a laboratory or specialized-function white room must be kept separately from regular, manufacturing uniform laundry. Items needed for this procedure are:

All materials are to be kept clean continuously, but especially in dealing with the washed and dried garments. The staff handling them must wear cleanroom garments THEMSELVES and use all the techniques of a standard cleanroom during the washing, drying, folding, packaging, etc. operations.

It is important to have a clear idea the level of cleanliness you need your garments to be, in regard to the class of your cleanroom. Logically, the higher the degree of quality your garments must be, the more stringent the techniques that will have to be utilized in your laundering methods and, therefore, the more the process cost will be per garment.

There needs to be a separate set of machines for synthetic garments. Once washed, the garment goes from the washer to a dryer with controlled, clean, and filtered air. The dried garments are then packed in a sealed bagall within the laundrys controlled environment. At that point the garments are ready for delivery to the user or customer.

Because any cleanroom garment is intended to protect the product or process from the personnel involved, these laundry precautions are needed by any cleanroom garment manufacturer:

*An anti-stat surface agent is a static-eliminating chemical that is put into the last rinse cycle water so that it sticks to the garment surface when dried. Because it absorbs moisture from the air, the static is reduced, BUT if too much is added, anti-stat flakes will particulate from the garments into the cleanroom.

The phrase cleaned and packaged in a cleanroom used by launderable garment manufacturers refers to several factors:

However, having a quality cleanroom garment cleaned, dried and handled in the proper cleanroom process, packaged in the correct packaging for the appropriate class of cleanroom will be of little value if the cleanroom personnel do not dress appropriately for the cleanroom! Each lab technician must treat the garment correctlywear their cleanroom garment properly secure it at the neck, down the front, and at the wrist and ankles. If the garment is not worn correctly, contamination pours out of the exposed area into the cleanroom. As a result, testing of the cleanroom (e.g. with a particle counter) will show that that worker is causing the general room contamination level to go up.

The working specifications of your cleanroom facility will determine what regular schedule and how stringent a procedure to monitor the airborne contamination. Military specs, for example, call for CONSTANT monitoring while others may require monthly, quarterly or annually. The more the room is monitored, the better the record of contamination control, so cleanroom class will probably be a major factor. Industry governing requirements often state that the cleanroom atmosphere be monitored in an ambient, unoccupied state to use as for baseline data and/or, for a reading of an operational contamination level, while the room is occupied and working.

Airborne contamination is typically monitored in one of two ways:

As a public service, listed below are some terms and definitions of common components of a cleanroom, quoted from Liberty Industries Your Guide to a Clean Room Facility. Because this periodically is updated and changes, we recommend getting the most up-to-date version from the Institute of Environmental Sciences and Technology or another credible source.

First and foremost, the homeowner needs to come up with the room addition cost estimate him or herself. And to do this he or she has to generate/obtain the room addition build plans, calculate the bill of material costs, and find, interview and hire all of the subcontractors. Then they need to schedule and manage the daily workings of a large team home construction project. So think twice before deciding to be your own general contractor on your room addition project. Now with all this said, Ill focus the rest of this article on estimating room addition costs.

This effort takes time and money, both in the design and construction of the room addition. Consequently home construction contractors charge a premium when providing a room addition cost estimate.Room addition cost estimates can vary dramatically due to a number of factors, chief amongst them being what is specified in the room addition plans. For example, room addition costs estimates of $80 to $130 per square foot for a basic family room addition is common.

If the room addition includes bathrooms and/or a kitchen, the room addition costs can easily escalate to $200-250 per square foot. So for example, if your room addition plans specify the construction of 400 square feet of family room living space, without any type of bathroom or kitchen area, you can expect to pay $32,000 $52,000 for a completed addition. If, on the other hand you are including a bathroom and/or kitchen, you could see room addition cost estimates as high as $100,000.

The contractor is in business to make money, and his time and effort is money, so you need to expect some premium charge for the materials that he orders and has delivered to your room addition project.When obtaining room addition cost estimates make sure your contractor provides you with a comprehensive construction bid that includes a checklist of all the tasks to be performed, the material to be used, and a detailed schedule of when the work will be performed.

The key to obtaining accurate room addition cost estimates is to have a complete set of room addition plans and specifications.

The more thorough your plan, the less likely for unwanted cost overrun surprises. By having a complete set of room addition plans, you can price out every single building material item, even down to the curtain rod. By including this level of specification you can avoid including TBDs and contractor allowances in the room addition cost estimates. TBDs and contractor allowances are the third rails of home addition projects as they inevitably lead to higher than anticipated room addition costs.

The average national cost of adding a room or building an addition is $41,739, with most homeowners spending between $21,006 and $64,718. This data is based on actual project costs as reported by HomeAdvisor members.

Many homeowners eventually come to that daunting dilemma: whether to buy their dream house or transform their current home into that dream. Once you make the commitment to build an addition, you've probably decided to go down the latter road. This decision might be something you've long considered, or it may have been thrust upon you by an expanding family. In either case, recognize that this will be a profound investment in time and money, but one that, if done properly, will enhance the value of your most important investment: your home.

You can choose from several types of additions for an average house, including ground level additions, second floor additions and detached additions. Each option has its own benefits, drawbacks and estimated prices based on factors such as the size of the structure and the features that you want to incorporate.

Return to Top

An extra room means exactly that. Homeowners who choose this type of an addition often do so to add a family room, bedroom or multiple spaces. When you want to add an additional room to your home, you typically have two options: build out or build up.

This is a major construction project that involves creating an additional building structure and integrating it with the rest of the home. Average costs run anywhere from $80 to $200 per square foot. No matter whether you build out or up, you should:

Building out typically involves adding a room at ground level, which is one of the most popular types of additions. These options increase the footprint of your home by extending the houses perimeter outward, which offers minimal disruption to the rest of the home. Potential drawbacks of building out include the cost of having to pour a new foundation, the loss of yard or property space and the possibility that you may need to get a zoning variance depending on local regulations.

If you want to expand your living space without increasing the footprint of your home, building up is a great option. For this type of addition, you add a room to the second story, or you could add an entire second story onto a one story home. Even though your contractor won't need to create a new foundation, he may need to strengthen the existing foundation to support the extra weight. On the downside, you need to check your town's rules to make sure you're not limited in the height of your home. Additionally, you'll need to add a staircase, which typically uses up 80 to 120 square feet of living space.

Sunrooms offer a budget-friendly alternative to a traditional house addition. Average costs run anywhere from $16,315 for the average sunroom, up to $70,000 or more for a 200-square foot addition with footings and a slab foundation. The cost of this project depends on the amount of space it adds, the location of the sunroom, extras such as electrical wiring and whether the room is heated (four-season room) or not heated (three-season room). Other considerations include hiring:

Buying a prefabricated sunroom runs around $11,000 per 150 square feet. Once you factor in adding heat, electricity and all the construction costs, it's not unusual to pay between $300 and $400 per square foot for the finished product. If you want to keep the costs low, consider adding the sunroom as a three-season room without heating.

Before you decide on a sunroom, get a few estimates to make sure youre getting the most competitive prices. Meet with a professional who can help assess the space, take accurate measurements and recommend the finishes and construction methods that will work best for you, your property and your climate.

Detached additions can range in style and price, with prefabricated, simple shed-like rooms running around $15,000 without electricity or heat, or full guesthouses that share similar costs as a detached garage addition, which run around $24,658 on average. Like the other types of additions, youll need a contractor to help install and finish your detached addition. Youll also need an electrician to add the necessary wiring and painters to finish the walls.

As with any other addition, the materials you choose have a direct impact on the cost of this project. Consider the following:

When youre planning your budget for this project, you need to consider many different factors, including the square footage and the size of the addition. The larger you go, the more expensive the project will be. Other important factors include necessary services, including:

Return to Top

The answer to this depends on the complexity of the addition. If youre adding a simple family room onto your home with one door into the rest of the house and one to the outside, a contractor should be able to handle it without the help of an architect. If you're moving walls, redesigning the way one room flows into another, adding a half loft and a spiral staircase or planning countless other complicated or intricate changes to your existing home, you may want to consider bringing an architect on board.

An architect will certainly add to your upfront costs on the project, but consider that a professional engineer can take your ideas and build them into something even more amazing. Also, by adding more clarity to your vision before construction starts, cost estimates will hit closer to the mark. When the project is done in partnership with an architect, you're also more likely to wind up with something that boosts your homes value.

Return to Top

Even if you have no plans to sell anytime soon, consider the resale value of your project. You might not always turn a profit on your home-expansion investment, but you should go into the job with realistic expectations about at least some kind of payback.

Because they're among the most expensive home projects, additions sometimes return less on your investment than remodels. If you're significantly adding to the square footage of your home or adding important types of rooms, such as bedrooms and bathrooms, your investment may pay off considerably.

Return to Top

Get everything in writing. First, agree on a total amount before discussing anything further.

It's reasonable for contractors to expect some money in advance, and then again after specific milestones during the course of the project. Be aware that shelling out too much money could put you at risk, and giving too little could put your contractor at risk. It's a delicate dance, but one that should be precisely choreographed before anybody fires up the power tools.

Still, no matter how detailed your plan is, remember that things happen. Find out about your contractor's change-order policy. Once you see your addition come to life, you may change your mind about the colors, fixtures or even the layout of the room. You may find that the contractor didn't understand your plan and made some decisions that didn't square with what you'd intended. Or, the addition may run into problems that neither you nor the contractor could have foreseen. Each of these could have enormous effects on the cost of the project, and each can cause friction with your contractor. Minimize the conflicts by spelling out, as clearly as possible on the front end, how each of these contingencies would be handled.

#1 Will the addition add value to my home?

Adding on to your home is among the priciest projects that you can undertake as a homeowner. Experts suggest that you can expect to see a return on your investment of:

#2 Will an addition look like it was tacked on?

Without the services of a designer or an architect, you could be left with an addition that looks like an afterthought or an obvious add-on feature. Skilled designers can create the space you want and deftly tie it into the existing structure so that it looks like it was always there.

#3 Do I need to worry about restrictions?

Always check with your local government to research zoning restrictions. In some areas, you may not be able to build within a certain number of feet of the front, sides or rear of the property lines. Other areas have rules about how much space on your property can be covered with buildings, how close you can get to protected spaces such as wetlands or how high you can build up.

#4 What should I look for in a contractor or a remodeling company?

Verify that the pros are licensed and insured. Check references and ask for pictures of their prior work. Ask the pros how long they've been doing this work, how they screen subcontractors and how long they expect the project to take. Get estimates from at least two or three contractors to get the most competitive prices and find the one that's going to work best for you.

#5 What should my first step be?

Create a plan for your new room, find a contractor to do the work and get all the necessary permits. This kind of a major project requires local permits to make sure the work is done according to building codes.

Return to Top

Adding on to a house is a very expensive project, but there are ways to shave money off your budget. For example, in some cases you may be able to remodel instead of add on. Maybe you could finish the basement (average cost $2,852) to provide an extra bedroom with a bathroom or a living space. Increasing the efficiency of your space can make an expansion unnecessary. For example, adding 200 square feet of space onto a kitchen could cost anywhere from $48,000 to $95,000. Swapping your old cabinets out for better-organized, custom cabinets costs around $35,000, but it might be all you need, which saves $13,000 to $60,000.

Other money-saving options include using detached additions instead of attached ones. A prefabricated detached structure could cost less than $20,000, and it could be used as a guesthouse or an office to provide the extra space that you want. Often, building up also saves money by avoiding excavation costs and the need for pouring a new foundation.

Lastly, consider how handy you might be. Tackle any DIY projects such as laying flooring, painting the walls or installing a new vanity on your own instead of paying a contractor to the work. Doing your own demolition, for example, can save you more than $500 in labor charges.

Saggio - Native American-Style Flutes & Hand Pans

It was after undergoing Reiki attunements, that Saggio discovered the primal sound of the Native American flute. It was as if some kind of cellular memory was triggered within him for the urgency to embrace this voice of the wind was overwhelming.

Although he had never made music before, his first encounter with the flute was a mystical union of wood, flesh, and spirit, a genuine heart-awakening. It was a coming home for both the flute and the flute player, a soulful reunion of long-separated friends.

And so it was at fifty-one years of age that Saggio started making music, Saggio said I cannot read or write music. I have no formal musical training, no constant mentor, and no coach.

The songs that come to Saggio always were and always will be in that place beyond words and thoughts, beyond separation, He becomes the flute and becomes the song.

Saggio states; It is without any regrets that I walked away from a former career as a high school English teacher to fully devote to performing and recording. Over the years I have had the opportunity to appear at Borders Books & Music, The Thunderbird Balloon Classic, Scottsdale Fiesta Bowl Art Walk, Mesa Arts Center, Chandler Center for the Arts, the West Valley Art Museum, and the University of San Diego.

His journey as a artist has enabled him to strike up friendships and acquire flutes from some of the most gifted flute makers across the country. His collection includes a wide variety of Native American style wood flutes in cedar, walnut, spruce, mahogany, cherry, maple, mesquite, bamboo, river cane, and kwila.

Mark Bensette Aux Bois - 6 & 12 String Guitar and Harps

Mark started his first rock band at 14, was performing at 16, and touring with concerts and bar gigs in Ontario and the northern United States through the 80s. He moved to the States in 1992 and continued playing with bands in Dallas, then Phoenix. After working a day job and playing in the band till 1 or 2 in the morning, Mark would decompress by turning to another music genre hed always enjoyed: New Age. Spending hours surrounded by loud music and walls of amplifiers, his head just full of that, hed listen to New Age or Classical music, something without lyrics, to unwind on the drive home.

After seeing a performance by Grammy award-winning harpist Andreas Vollenweider Mark found he loved the music and style and promised to one day create New Age music. When Mark took up the concert harp in 2006 he discovered there was no training at all, its all just instinct. Mark found himself with another self-taught instrument under his belt, then put together a home studio and produced three New Age CD's.

In 2009 Mark was diagnosed with cancer. During this time, he lost all interest in music - frustrated and disillusioned, and not finding anyone suitable to work with, he applied his talents instead to poetry and fiction, writing the Son of Sherlock Holmes series.

It was watching an episode of That Metal Show that reignited the spark. Guest Jack Blades from Night Ranger said you know, when you stop creating, you die inside. With that, Mark started writing and auditioning singers. He also reconnected with musician and recording artist Saggio, whom he had met ten years prior.

Just as a butterfly - the Papillon - adapts and transforms, with Marks innovative style, he will no doubt find a way to incorporate his love of Rock music with his appreciation of New Age, Classical and other genres into the musical collaborations of Nouveau Papillon and Thunder Of Silence.
