Danforth Village's 1920s and 1940s semis and bungalows are ideally suited to second-storey additions and open-concept kitchen renovations — the two projects that define this family neighbourhood's renovation market. Kopman Build has delivered these projects along the Danforth corridor from Greektown to Woodbine for over 25 years.
The Danforth Village housing stock is wonderfully consistent — brick semis and detached bungalows built between the wars, with generous lot depths and tight party-wall relationships that demand a contractor who understands pre-war construction. Knob-and-tube wiring, cast-iron drains, and balloon-framed walls are the norm, not the exception. Kopman Build's crews know these buildings and plan around their realities from day one. Three things define renovation work here:
Dustin Kopman founded the company in 1999 after growing up in construction through his family's firm, G& G Enterprise. Every Kopman Build project is managed by someone who understands the craft — not just the sales pitch.
Full second-storey additions on bungalows and semis — structural engineering, City of Toronto permits, and seamless integration with the existing facade.
Load-bearing wall removal, beam installation, and full kitchen remodels to create the open main floors Danforth Village families are after.
Legal secondary suites, family rooms, and home offices finished to Ontario Building Code in pre-war foundations.
Primary ensuites, main baths, and powder rooms — complete gut-and-rebuild or targeted upgrades in tight pre-war floor plans.
Multi-phase whole-house renovations — electrical, plumbing, insulation, and finishes — managed as one coordinated project from a single team.
Experienced with the structural and material conditions typical of 1920s–1940s Toronto housing, including party-wall coordination on semis.
We visit your 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.
We manage all permit applications, engineering consultants, and approvals — 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.
A second-storey addition on a typical 1920s–1940s Danforth Village bungalow generally runs $250,000–$450,000+, depending on the footprint, structural conditions, and finish level. The existing foundation and framing are assessed during pre-construction to identify any remediation work before pricing is finalized.
Yes. Second-storey additions require a building permit from the City of Toronto, along with structural engineering drawings and a zoning review. Many Danforth Village properties also fall under Toronto's Zoning By-law 569-2013, which governs lot coverage and setbacks. Kopman Build manages the full permit process from application through final inspection.
A kitchen open on a Danforth Village semi typically involves removing the wall between the kitchen and the rear living or dining space to create a connected, open layout. Because many of these walls are load-bearing, the work requires a structural engineer, a permit, and an LVL or steel beam to carry the load. The result is a significantly more functional main floor — the most requested renovation in the neighbourhood.
Whole-home renovations on pre-war Danforth Village semis typically run 6–12 months depending on scope. Knob-and-tube electrical, cast-iron plumbing, and balloon framing are common in this housing stock and are factored into the project plan during pre-construction. We build realistic schedules and update you weekly throughout construction.
Yes. We regularly work on both semi-detached homes and detached bungalows throughout the Danforth corridor from Greektown to Woodbine. Each building type has its own structural considerations — shared party walls on semis, wider rear yards on detached bungalows — and we tailor our approach accordingly.
