Home Additions

More space, built to belong.

From a sun-filled family room to a new primary suite, we design additions that look like they were always part of your home.

Home Additions

Grow your home without moving.

An addition gives you the space you need while keeping the neighbourhood you love. We plan the design, structure and finishes together so the new space blends in, inside and out.

We also build custom lofts and one-of-a-kind built-ins, and our outdoor woodworking team can connect your new space to the backyard with a deck or pergola.

Do I need a permit for an addition?

Almost always. We'll help coordinate the drawings and permit process and build the approval time into your schedule.

How long does an addition take?

It depends on size, design and approvals. You'll get a written timeline before construction begins.

Can you match my existing home?

Yes. We aim to match materials, trim and finishes so the addition feels original to the house.

Yes. Our outdoor woodworking team builds decks, pergolas and fences, so the addition and the backyard can be designed together.
