Why Build a New Garage?
If you can afford it and have enough space, building a new garage can also make your home more attractive to buyers. On average, a garage adds to home value by providing an 60-80% return on investment.
It can also be a great space for storage, hobbies (art, woodwork, car building, gaming) and added living space/space for entertaining guests
Finally, you may want to build a garage to replace an existing structure that’s aging, damaged or unsound.
What Are Some Hints and Tips for a Building a New Garage?
When building, consider these helpful bits of advice:
1. Pick the right time of year. In a climate with freezing winters, build in early spring, summer or fall to avoid weather delays.
2. Think about the future. The new space should provide room for storage and vehicle needs down the road.
3. Talk to the pros before you make permanent plans.A specialist building pro can help you think through your needs and budget.
4. Make sure it matches. If it clashes with your house, it might reduce its curb appeal and value.
What Are the Benefits of Converting Your Garage Space?
Many families need more living space or storage and parking. With a little planning and the right vision, a garage can find many new uses:
![Cost Cost](/uploads/1/2/4/9/124927729/129205185.jpg)
1. An added bedroom. Families grow in all sorts of ways, from new children to older relatives needing care. Extra sleeping space is also useful for guests.
2. More living space. Rather than building a new room, this space can become a family room, dining area or game room.
3. A studio or office. More and more companies let their employees work remotely. This requires office space at home.
4. An apartment. Added income can be important for a home. Changing it into an apartment could provide some help in paying the mortgage.

How Do You Maintain Your New Garage?
Once you’ve built a new garage or remodeled your current one, you’ll want to keep it well-maintained. These guidelines will help keep your structure sound:
1. Tune up your door every year. Checking the mechanical systems and replacing the weather-stripping should keep it in smooth working order.
2. Clean the gutters at least two to three times each year. Failure to manage runoff can speed up wood decay or harm the foundation.
3. Reseal your concrete floors every few years. This helps to keep water out, and prevents gasoline or stored chemicals from eating at the concrete.
4. Power-wash and paint the structure regularly. It provides a tidy look and keeps moisture and decay at bay.
How Do You Hire a Garage Builder?
As with any major home project, you’ll want to thoroughly vet the pros you ask to bid on the job:
- Get at least three estimates.
- Seek out a licensed builder.
- Make sure they have current bonding and insurance.
- Ask if they have practice building these structures.

You want to build a new house, but can you afford it? What kind of house do you want to build? To plan your budget, start with one or more of the many free online building cost estimators — but first you'll have to know the answers to some of the things you might not have thought about.. Then you'll have to look for hidden costs that will add to your final bill.
To get you started, here are some tips from building plan expert Ken Katuin — a tech-saavy professional with many years working in the home design Industry.
How to 'Guesstimate' the Cost to Build a House
Meet with builders who construct houses that are similar in size, quality, and features to the home you want. Builders will tell you how much per square foot they usually charge for home construction. They can also give you a ballpark idea of what your dream home might cost. However, it is important to know exactly what is included in the price. If you ask, some builders will provide you a list showing the materials they will use.
Look at newly constructed homes that are similar in size, style, quality, and features to the home you want. Take the price of the home, deduct the price of the land, and divide that amount by the square footage of the home.
For example, if the home is selling for $230,000 and the land costs $30,000, then the construction cost is around $200,000. If the home is 2,000 square feet, then the cost per square foot is $100.
Use several new homes in your area to get an approximate square footage price. After you have calculated an average square footage cost, you can multiply that cost by the finished square footage of your house plan to get a ballpark estimate.
The most expensive areas in a home are usually the bathrooms and the kitchen. The number of windows and the size and quality of windows can also affect the cost. Vaulted ceilings and high roof pitches can increase the cost of a home. When using other homes to calculate an estimate, be sure the home has a similar style and features of the home you plan to build.
The cost per square foot is often higher for a small home than that of a larger home. When building a larger home, the cost of expensive items (such as a furnace or kitchen) is spread over more square footage. Consequently, a larger home may have a lower square footage cost than a smaller home. Also, it usually costs less to build a two-story home when compared to a one-story home that has the same square footage. This is because a two-story home will have a smaller roof and foundation. Plumbing and ventilation are more compact in two-story homes.
Small details in the design of your home can make a big difference in the price. To save on costs, begin estimating construction expenses before you select your final blueprints. Here are important factors to consider:
Size of Home: When building a home, it's best to work with even numbers. Have your home size rounded up or down to increments of two feet. This reduces wasted materials. Also, it's most economical to build a home that is no deeper than 32 feet. If the depth exceeds 32 feet, then your roof trusses may need to be specially designed and will be more expensive.
Architecture of Home: Homes that have a rectangular or box shape cost less to build. Having more angles and corners in the architectural design of your home can increase the amount of labor and materials needed to build. Dome shaped homes often make efficient use of materials and tend to cost less than other shapes.
Site Preparation: Preparing a site for construction can have a big impact on the cost of a home. Building on a flat lot will usually cost less. If you have to haul in lots of dirt, do a lot of grading, clear trees, or blast through large rocks, then site preparations can become more expensive.
Cost Overruns: Usually the finished cost of a home is more then the original bid price. Cost overruns occur from overspending the allowances, making changes, and encountering unforeseen problems. Proper planning can greatly reduce cost overruns. In general, it is a good idea to allow an additional 10% to cover unexpected costs.
Inflation and Market Conditions: Usually the cost of building a home increases around 3% to 6% per year. If it will be several years before you begin construction, remember to include inflation into the cost estimate for your home. When using other homes to compare prices, try to use homes that have been built within the last six months.
So, How Much Will Your New Home Cost?
It's all in the timing. The famous architect Frank Gehry once presented his design vision to a client (probably more than once), and the client's first remark was, 'How much is this going to cost?' Gehry responded that he didn't know. Say, what? With all of the variables listed here, market fluctuation may be the most important. The time of year, the region's climate, local building code regulations, the local and national economy — all affect labor costs. This is why home cost estimates are binding for only a certain number of days — labor costs can change quickly.
Here's a big warning: if a contractor's estimate stays the same year after year, check the materials list. Construction costs can be absorbed by lowering the quality of materials.
Although sometimes costs do go down, playing the market is risky. If you need to, examine every idea that can cut costs without compromising comfort and beauty. It's so easy to be talked into things — even the casual mention of a new product can be seducing. Also, ask questions and know the lingo — don't be taken in by acronyms you don't understand. For example HSF means 'Heated Square Feet,' so question why a garage or attic would be included in the total square footage.
Building a house is about design and construction — there may be wiggle room in each. Residential architectural fees can be well-worth it in a world where the cost per square foot to build a house is constantly changing. Design architects can help you understand the changing costs of construction.
The steps to building your own home can be stressful. Building a new house is a process filled with decision-making. It's not for everyone. Ultimately it's like a lot of things we do in life — you can wait around for the swimming pool water to get warm enough, or you can jump right in. Just make sure you're dressed appropriately.
