Seamless Transition

When adding space to an existing house our team will e3nsure a seamless transition from the old to the new as if your addition was built and designed as part of the original home. This can be done by minimizing awkward transitions or routes to get to the new space, or choosing trim and moldings appropriate to the homes history and style.

Second floor / Top Up Additions

The most common addition for an urban home is a second floor or top-up addition to add square footage to your home vertically. This type of project consists of removing the original roof, building up one or two floors then restoring the roof. A great way to add space and value to your home.

Bump Out or Side Addition

If you have the space on your property then a bump out or side addition is a cost effective choice to add space to your home. An additional advantage is you most likely do not need to move out during the renovation as our team will be adding space beside your living space.

“D2 Build is the best contractor I have ever hired for a job. D2 designed and built an entire home renovation for my current home. I give D2 the highest possible recommendation and have already passed them onto many friends and family for all types of projects.”

“We dreaded the thought of renovating our home. We have heard so many horror stories of how badly things can go. We asked D2 to renovate our detached bungalow and they did not disappoint. They are knowledgeable, experienced, know what to prioritize, and where your money is best spent. Most of all, they have incredible integrity.”

Yes, permits are required for home additions in Toronto, whether it’s a full house extension or adding a second floor to your house. In order to get started, the homeowner would need a survey of their property. If the owner does not have one, and would like to know if there is one on public record, click here. By selecting D2 Build as your home addition contractor, we will guide you through this process to ensure compliance with local building codes.
The simple answer is no. During the process of renovation electricity and plumbing gets disconnected, a large amount of dust is generated, and a lot of noise is created, making it a disruptive space to reside in. This said, living in the house during a home addition is possible during certain types of renovations, but for larger projects like adding a second floor to a house, you will likely need to relocate for a portion of the project. Discuss this with your home addition contractor for specific advice.
The initial process to obtain a building permit is generally 2-3 months, and a typical house extension takes 3 to 6 months.
