The approach
Basement Renovations done properly
A finished basement is the single largest square-footage gain most homes can make. We start with moisture, insulation and egress, then build the rooms you'll actually live in — home theatre, gym, wet bar, wine cellar, in-law suite.
Dry, warm, permanent
Moisture management, insulation and framing detailed for Ottawa winters and Ottawa spring melts.
Rooms with a purpose
Theatre rooms, wet bars, wine cellars, gyms, guest suites and legal secondary units.
Permits handled
Egress windows, ceiling heights and separations coordinated and inspected — we manage the paperwork.
