Garage additions

An attached or detached garage that matches the house, keeps the cars out of the snow, and finally gives you somewhere to put everything else.

The work

A garage is a foundation, a frame, a roof and a door — but in Ottawa it is also frost depth, grading, drainage and a permit. Skipping any of those is what causes a garage slab to crack or a door to bind after two winters.

Attached garages carry extra requirements: a fire-rated separation from the house, a self-closing door, and a sealed floor assembly to keep exhaust out of the living space. We build those details as a matter of course.

Most clients want more than parking. Overhead storage, a workshop bay, a car lift allowance, insulation and a heater are all worth deciding at the framing stage rather than retrofitting later.

Typical duration
8 – 14 weeks
Permits
Building permit; zoning review for setbacks and lot coverage
Options
Attached or detached, single or double, workshop or storage loft
Season
Foundations best poured before deep frost

How we build it

What's included, and why it matters

01

Frost-depth foundations

Footings poured below the local frost line, with a properly prepared and reinforced slab that won't heave.

02

Matched exterior

Siding, brick, trim, soffit and roofing selected to match the existing house so the garage doesn't read as an afterthought.

03

Insulated and heat-ready

Wall and ceiling insulation, an insulated door and wiring for a heater, so the space works in February.

04

Grading and drainage

Apron, slope and drainage designed so meltwater runs away from the slab and the house.
