Roncesvalles draws buyers who want to live inside a real neighbourhood — one defined by early 20th century worker cottages and semis, and anchored by the vibrant Polish-heritage commercial strip along Roncesvalles Avenue. Kopman Build has spent over 25 years delivering custom home builds and full gut renovations across Toronto, and we know how to unlock the full potential of these properties — structurally, spatially, and on budget.
Roncesvalles is gentrifying rapidly, and the demand for gut renovations of Victorian and Edwardian semis is intense. The homes are charming — but the bones are over a hundred years old. Knob-and-tube wiring, rubble-stone foundations, and undersized structural members are the norm, not the exception. That reality requires a builder who has seen it before and knows how to price it honestly.
The neighbourhood's Polish-heritage commercial strip along Roncesvalles Avenue gives the area a distinct urban character — one that attracts buyers who want to live in the fabric of the city, not a suburb. Those buyers expect their homes to match the quality of the streetscape: well-built, thoughtful, and lasting.
Kopman Build brings over 25 years and 400+ projects to every engagement — and Dustin Kopman is personally involved in each one. That means no handoff to a junior project manager mid-build, and no surprises buried in a contract that was written to protect the builder, not the client.

Structured handover and a 12-month attendance window. The relationship doesn't end at move-in.
Yes. Full gut renovations of early 20th century worker cottages and semis are among the most active project types we manage in Roncesvalles. We handle structural upgrades, new mechanical and electrical, insulation improvements, and complete interior rebuilds — while preserving the exterior character the neighbourhood is known for.
Most full gut renovations and additions in Roncesvalles require a building permit from the City of Toronto. Projects involving structural changes, new additions, or alterations to heritage-adjacent streetscapes may also require Committee of Adjustment approval or heritage consultation. Kopman Build manages the full permit process on behalf of our clients.
A full gut renovation of a typical Roncesvalles semi-detached — 2,000–2,500 sq ft — generally ranges from $450 to $700+ per square foot depending on scope, finishes, and structural requirements. We provide detailed pre-construction budgets with line-item allowances before any commitment is made.
We work across Toronto and the GTA, and Roncesvalles is a neighbourhood we know well — including its housing stock of early 20th century semis and detacheds, the active gentrification dynamic, and the zoning and heritage context that shapes what's achievable on each lot. Our projects in the area range from full gut renovations to rear additions and complete custom rebuilds.
