Construction · Additions

More house, without moving.

Second stories, rear additions, garage conversions, in-law suites. We add to the home you already love.

An addition is two projects at once: a new building has to land cleanly on an existing one. The structural connection, the roof tie-in, the heating and electrical that has to expand to feed the new rooms — every joint matters. We've done enough of these to know where the pitfalls hide.

What we handle

Second-story additions

Adding a full floor on top of an existing one-storey or 1.5-storey home. Structure, roof, stairs, mechanical.

Rear and side additions

Extending the footprint — kitchens, family rooms, primary suites, sunrooms.

Garage conversions

Turning an attached or detached garage into livable space — guest suite, home office, gym.

Laneway and coach houses

Backyard suites where zoning allows. Toronto's laneway housing program is well-established now.

In-law and basement suites

Separate-entrance suites for multigenerational living. Includes egress, separate mechanicals, and proper sound isolation.

Notes from the GTA

  • Most GTA additions require a Committee of Adjustment variance unless the lot is generous; we plan the design around what's likely approvable.
  • Tying new framing to old framing requires careful structural engineering — old houses settle, sag, and surprise.
  • Toronto's Garden Suite and Laneway Suite programs have specific requirements; we know which lots qualify and which don't.
  • Heat and electrical loads almost always need upgrading when you add 1,500+ sq ft of conditioned space.

An addition done well doesn't look added.
