Danforth Village's 1920s–1940s semis and bungalows — stretching along the Danforth corridor from Greektown to Woodbine — are prime candidates for integrated design-build: second-storey additions, main-floor kitchen opens, and whole-home renovations where one coordinated team removes the risk of working through century-old walls. Kopman Build has managed exactly this work since 1999.
Danforth Village is a family renovation market. Owners of 1920s and 1940s semis and bungalows along the Danforth corridor are growing into their homes — adding a second storey, opening a cramped kitchen to a rear addition, or converting an underused basement. These projects cross the line between design and construction constantly: a structural engineer weighs in, a load-bearing wall moves, a floor joist needs sistering. When design and construction are managed by separate firms, every one of those moments becomes a dispute about fees, responsibility, and schedule. Design-build eliminates that entirely.
Kopman Build coordinates design, structural engineering, permitting, and construction under one management structure. Dustin Kopman founded the company in 1999 after growing up working in construction through his family's firm, G&G Enterprise — meaning every Danforth Village project is overseen by someone who understands the craft of older Toronto housing, not just the sales process around it.
Three things matter most for Danforth Village clients specifically: first, older homes here routinely reveal knob-and-tube wiring, rubble foundations, and undersized structural members once walls open — a design-build team absorbs and resolves those discoveries without inter-firm disputes. Second, second-storey additions on bungalows require City of Toronto permits, zoning review, and structural engineering that we manage from day one. Third, the Danforth corridor is a family neighbourhood where minimizing construction disruption to daily life matters — our full-time site supervision keeps schedules tight.

We visit your Danforth Village property, listen to your goals, and document the project in writing — scope, budget, and timeline.
A detailed line-item estimate with allowances and contingencies, so you know the number before committing — including structural and older-home risk allowances.
We manage all City of Toronto permit applications, zoning compliance, engineering consultants, and approvals — nothing falls through the cracks.
Full-time site supervision, weekly updates, and open-book cost tracking throughout the project — with same-team resolution of any discoveries in older-home walls or floors.
Structured handover with all documentation, warranties, and a 12-month attendance window post-completion.
Yes — it is particularly well-suited to the 1920s and 1940s housing stock along the Danforth corridor. These homes often present hidden conditions behind plaster walls and under subfloors that affect scope and cost mid-project. With design-build, the same team that designed the addition or kitchen open is managing the field, so discoveries are handled immediately without disputes between an architect and a separate contractor.
A full second-storey addition on a Danforth bungalow typically ranges from $350,000 to $600,000 depending on the footprint, structural requirements, and finish level. The design-build model gives you a costed estimate before design is finalized — so you are not committed to drawings that exceed your budget. We scope the structural, mechanical, and envelope work together from day one.
We manage the full permit process for all projects in Danforth Village, including building permits through the City of Toronto, zoning compliance under the Toronto Zoning By-law, and any Committee of Adjustment applications if the scope requires it. You do not need to navigate City Hall — we handle it as part of the engagement.
Yes. Kitchen opens and main-floor reconfiguration on Danforth semis require a structural engineer to assess load-bearing walls — a step we include in every design-build engagement. Our team coordinates the engineering, designs the beam and column solution, and builds it, so there is no gap between what the drawings show and what is physically possible in your specific home.
