Bloor West Village's 1930s–1950s brick homes and bungalows are ideal candidates for thoughtful vertical and rear expansion — and Kopman Build has been designing and building those additions in Toronto's west end since 1999. Whether you're growing your family's footprint or opening up a closed-off main floor, we manage every step from feasibility through final permit sign-off.
Bloor West Village is a family-oriented neighbourhood where staying put and expanding often makes more financial sense than moving — especially given the premium that proximity to the Bloor strip, transit, and top-ranked schools commands. A well-executed home addition here is one of the highest-return investments a homeowner can make.
The 1930s and 1950s brick homes that define the streetscape require a contractor who understands older masonry construction: load-bearing wall assessment, foundation capacity, and matching heritage-sensitive exterior finishes all matter. Kopman Build brings that technical depth to every project, along with in-house permit management so nothing stalls in the approval queue.
Dustin Kopman founded the firm in 1999 after growing up working in construction through his family's business, G&G Enterprise. That hands-on background means projects here are managed by someone who understands the craft — not just the estimate.

Home addition costs in Bloor West Village depend on scope and the condition of the existing structure. A second-storey addition on a 1930s–1950s bungalow typically runs $350,000–$650,000+ due to the structural work required to integrate with older masonry. A single-storey rear addition runs $220,000–$420,000+. Kopman Build provides a detailed line-item estimate before any commitment.
Yes — second-storey additions are one of the most popular projects in Bloor West Village, where the 1930s–1950s bungalow stock offers excellent footprints for vertical expansion. The key considerations are structural capacity of the existing foundation and walls, zoning setbacks, and heritage character guidelines in certain blocks. Kopman Build has done this work in the neighbourhood and will assess your specific property.
Yes. All home additions in Toronto, including Bloor West Village, require a building permit from the City of Toronto. Many projects also require a zoning review and, depending on the proposed size, a Committee of Adjustment minor variance application. Some streets in the area fall under heritage overlay policies that influence exterior materials and massing. Kopman Build manages the full permit and approval process.
A rear addition typically takes 6–10 months from permit approval to completion; a second-storey addition takes 8–14 months. Permit applications in Toronto currently add 4–8 months before construction can begin. Older homes in Bloor West Village may require additional time for structural upgrades or masonry work. We give you a realistic full-project timeline at the outset.
