Danforth Village's 1920s–1940s semis and bungalows — running the corridor from Greektown to Woodbine — are among Toronto's most in-demand candidates for second-storey additions and kitchen-open rear extensions. Kopman Build has been building home additions across Toronto since 1999, handling the structural complexity and permit requirements these older east-end homes demand.
The Danforth corridor between Greektown and Woodbine is a family renovation market. Owners of 1920s–1940s semis and bungalows are typically weighing a second-storey addition against the cost of moving to a larger property in a less central neighbourhood — and increasingly, the addition wins. But these older homes carry structural complexity: balloon-frame or post-and-beam construction, undersized foundations, and shared party walls on semis all require careful assessment before a single nail is pulled.
Kopman Build approaches every Danforth Village project with a structural feasibility review built into the initial consultation. We document the existing condition, scope the required upgrades, and price them into the estimate before any commitment. Families get an honest number upfront — not a surprise once walls are open.
Dustin Kopman founded the company in 1999 after growing up working in construction through his family's firm, G&G Enterprise. Every project is managed by someone who understands the craft — not just the sales pitch.
Full second-storey additions on Danforth Village bungalows — doubling your living space on the same footprint, with structural integration built right from the foundation up.
Single- and multi-storey rear extensions that open up the back of your semi or bungalow, typically paired with a kitchen redesign and main-floor open concept.
A combined scope common on Danforth semis: extend the rear, remove load-bearing walls, and create an open kitchen and living area that connects to the yard.
Where your lot and lane access allow, a laneway suite adds rental income or multigenerational living space. We assess eligibility as part of your initial consultation.
Garden suites in rear yards as permitted under Toronto's expanded as-of-right zoning — a growing option for Danforth Village lots with sufficient rear yard depth.
Smaller additions — mudrooms, sunrooms, side bump-outs — designed to integrate cleanly with the existing architecture of your Danforth-area home.
We visit your Danforth Village property, assess the existing structure, 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.
We manage all permit applications, engineering consultants, and any Committee of Adjustment hearings — nothing falls through the cracks.
Full-time site supervision, weekly updates, and open-book cost tracking throughout the project.
Structured handover with all documentation, warranties, and a 12-month attendance window post-completion.
Home addition costs in Danforth Village depend on the scope and the condition of your existing 1920s or 1940s-era home. A second-storey addition on a bungalow typically runs $320,000–$600,000+. A rear addition ranges from $200,000–$400,000+. Older semi-detached homes often require additional structural work, which we factor into our pre-construction estimate before any commitment.
Yes. Second-storey additions are one of the most common projects we do along the Danforth corridor. Most bungalows in the area were built in the 1920s–1940s and can support a full upper floor addition with the right structural preparation. We assess the existing foundation and framing as part of our initial feasibility review.
Yes. All home additions in Danforth Village require a City of Toronto building permit, and many semi-detached properties in the neighbourhood require a minor variance from the Committee of Adjustment due to lot coverage and setback constraints. Kopman Build manages the full permit and approval process, including any variance applications.
A rear addition on a Danforth Village semi or bungalow typically takes 6–10 months from permit approval to completion. A full second-storey addition takes 8–14 months. Permitting and any Committee of Adjustment hearings can add 4–9 months before construction begins. We give you a realistic total timeline from your first consultation.
