When moving up costs hundreds of thousands, finishing the basement is how the city's century semis, post-war bungalows and rebuilt customs grow, and the rebuilt customs are where our luxury basement renovations in Toronto tend to happen. Leaside, the Danforth, North York and Scarborough each bring their own foundations, and we've worked under all of them.
Older Toronto streets mean lower ceilings and mature-home moisture. Underpinning, benching and waterproof-first construction are our specialty, not surprises. And with secondary suites now permitted as-of-right across most of the city, a finished Toronto basement can also become the GTA's strongest rental income.
Theatres, bars, gyms and family spaces. Wood studs with metal tracks and moisture-resistant drywall as standard, finished to match the rest of your home.

Underpinning for ceiling height, waterproofing, and permitted separate entrances for legal Toronto second suites.
EXPLORE STRUCTURAL WORK →Toronto is the one city where ceiling height decides the project. In Leaside, the Danforth, East York and the older streets of North York, the houses are pre-war brick semis and detached homes on rubble-stone or block foundations, and their basements were dug for a furnace and a coal chute, not a family room. Six and a half feet under the joists is common, and ductwork and beams cut into that further.
That is where underpinning comes up. Digging below the existing footings and pouring new ones takes a Toronto basement to eight feet or more, and full-perimeter underpinning runs $60,000 to $120,000 before any finishing. It is a real number, and we say it early, because some homeowners would rather live with a seven-foot ceiling and put that money into a bathroom and a bar. Either answer can be right. The wrong answer is finishing a low, damp basement and paying twice.
Rubble foundations also need attention before drywall: parging, interior drainage and a proper vapour strategy. We build the waterproofing first and the pretty parts second.
Permits go through Toronto Building, and structural work means engineered drawings, which we coordinate with the engineer and the inspector.
Our nearest project is on Fortrose Crescent in North York, quoted in August 2026 with a 75-day guaranteed completion: 815 square feet with a gym behind glass, an office, a laundry closet and a five-foot bar. From Richmond Hill, most of the city is about 30 minutes away.
Every basement is priced from the same quote sheet, line by line. Permit drawings, 3D design and the lifetime workmanship warranty are included.
We have not published a finished Toronto project yet, so here is our nearest one, quoted in August 2026 with a 75-day guaranteed completion in North York, built to the same specification and warranty we bring to Toronto.
The design puts a gym behind a single glass door with sliding mirror closet doors, a home office, and a stackable laundry closet with sink plumbing. The bathroom gets a custom tiled shower on a Schluter-KERDI system, the lounge a 5-foot bar and a 60-inch Napoleon linear fireplace, with two closets, eight doors and 22 pot lights.
