Regardless of where you’re in need of space, there is a home extension solution that can solve the problem. Our team specializes in the professional design and development of a wide range of home extension Toronto solutions, including the following:

  • Second-Story Additions – The best way to increase the square footage of your home without requiring more additional land is to take advantage of a second-story addition. Whether it’s needed for bedrooms, living areas, or completely separate living space, a second-story addition will allow you and your family to enjoy the home you have for years to come.
  • Rear Extensions – For families needing more than a simple room addition, rear extensions may be a valuable route to take. With rear extensions, you’ll be able to extend the entire rear of your home – including the basement, main floor, second floor, bungalow additions or all of the above. With a rear extension, you’ll be able to improve square footage without restructuring the flow and layout of your existing home.
  • Kitchen Additions – Running out of room to cook and host? Expand your kitchen square footage to ensure that you have enough counter and floor space for any event with a home kitchen addition.

Will putting an addition on my house add value to my home?

Yes! Any home addition will undoubtedly add significant value to your house.

Does a home addition require a permit?

According to the Building Code Act, any construction and/or demolition of a new building, addition, or material alteration requires a building permit. So yes, a home addition does in fact require a permit.

Do I need to move out during a home addition?

Are there any limits for home additions?

There are no limits for home additions. The only factor that would restrict what you may or may not add to your home is because of law limitations. Bylaws may limit the size of a home addition by imposing setback requirements in the front, side, and rear yards, and by controlling maximum height.
