– What you need to know!
If you think your home is too small and you need additional rooms, opting for a home addition — instead of buying a new house — is often times the best way to go. Whether you’re building on top or off of your existing home, your home addition project is not only the perfect opportunity to rethink your living space and increase the value of your home — it’s also easier and less expensive than a move.
What is the cost of a home addition?
The price of a home addition can vary significantly, but in the following table you’ll see the average market prices:
|Type of House Addition||Average Cost
Hardware and Labor
|Addition of floor (rough)||$100 to $125/ft²|
|Addition of floor (turnkey)||$145 to $175/ft²|

Building on or off of your existing home
Home additions come in many shapes and sizes — from finishing your basement and converting your sunroom to these major projects:
- Adding a second story
- Building a garage or an extension
- Adding a rearward extension
- Building a solarium or porch
- Building a room above the garage
- Transforming a single-family residence into a multi-generational home
Depending on the configuration of your home, the most commonly considered solutions are a foundation expansion, with or without a basement, a pile expansion, adding a garage, or building an additional floor. It should be noted that the addition of a floor requires a structure and foundation strong enough to accommodate the extra weight.
A home expansion is a great opportunity to rethink your living space and can, if done well, significantly increase the value of your home. It is also a project often more advantageous and less expensive than a move when you begin to calculate the costs and benefits. Improving and expanding on the home you love can prove to benefit your own standard of living whilst also being a financially wise investment.
Prepare for a well-planned home addition that pays for itself over time
Home additions are a big undertaking, but a well-planned home addition project will pay for itself day after day, year after year. Whatever your house addition project, you need to keep these two rules of thumb in mind:
Rule #1: With a major home addition project, no decisions should be made lightly or unexpectedly. Without a professional customized plan, you could seriously damage your home architecturally, structurally and aesthetically.
Rule #2: Relying on the expertise of a proven home addition expert, such as an architect and/or engineer, ensures the success of your home addition project.

Planning for a home addition project
A home addition project can take many months of planning to obtain the permits and authorizations from your city (if required). An expansion project is very similar to a new construction and involves almost as many steps.
If you’re thinking about managing every step of your home addition yourself, you may want to think about it twice. Some home addition projects can require up to 20 different professionals on the project whom you would need to schedule to your agenda and pay even during any delays that occur between different jobs which may require a contractor to work longer than expected. It’s often wiser to let a professional General Contractor work full time on your project so you can continue your day-to-day with peace of mind.
