Lawrence Park's generous lots and 1920s–1940s Arts and Crafts and Tudor Revival homes are ideally suited to thoughtful additions — but matching their character demands a contractor who understands the architecture. Kopman Build has been building home additions in Toronto neighbourhoods like Lawrence Park since 1999.
Lawrence Park's stock of 1920s and 1930s Arts and Crafts bungalows and Tudor Revival two-storeys sits on lots large enough to support meaningful additions — rear extensions, full second storeys, and finished basement in-law suites. But these homes carry strong architectural identities, and additions that ignore the original character diminish the property rather than improve it. Kopman Build brings both the technical skill to integrate structurally and the design sensibility to match in material and proportion.
Some Lawrence Park properties carry heritage designation or fall within Heritage Conservation District guidelines, adding an approval layer that requires early planning and close coordination with the City. We identify this at the outset and manage the process in full — permits, heritage approvals, and engineering — so nothing delays your project at a critical moment.
Dustin Kopman founded the company in 1999 after growing up working in construction through his family's firm, G&G Enterprise. That hands-on background means every project is managed by someone who understands the craft — not just the sales pitch.
Single-storey and multi-storey rear additions that expand kitchens, family rooms, and principal living areas while respecting the home's original front elevation.
Full second-storey additions on Lawrence Park bungalows — doubling living space on a lot that's already in the neighbourhood you want.
Finished lower levels configured as self-contained in-law suites, coordinated with any above-grade addition scope for a unified project delivery.
Addition scopes that include full custom kitchen and bathroom work — millwork, stone, plumbing fixtures — finished to a standard that fits Lawrence Park homes.
Additions to designated or character properties, managed through the City's Heritage Planning division with matching materials and period-appropriate detailing.
Smaller additions — mudrooms, sunrooms, bump-outs — designed to integrate cleanly with Arts and Crafts and Tudor Revival architecture.
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, heritage approvals where required, engineering consultants, and City 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.
Home addition costs in Lawrence Park reflect both the neighbourhood's premium land values and the care required to match existing 1920s–1940s Arts and Crafts and Tudor Revival architecture. A single-storey rear addition typically runs $220,000–$420,000+; a full second-storey addition runs $350,000–$650,000+. Heritage-sensitive detailing and custom millwork to match original character adds to the budget. Kopman Build provides a detailed line-item estimate before any commitment.
Some properties in Lawrence Park carry heritage designation under the Ontario Heritage Act or fall within areas subject to Heritage Conservation District guidelines, which require approval from the City of Toronto's Heritage Planning division in addition to a standard building permit. Kopman Build identifies heritage status early in the planning process and manages all required applications and consultations.
Yes — this is a core part of our work in Lawrence Park. We source matching brick and stone, replicate original window proportions, and work with millworkers experienced in period-appropriate trim and joinery. Our design-build approach means architectural intent and construction execution are coordinated from the start, so additions read as belonging to the original home.
Absolutely. Many Lawrence Park homeowners combine a rear or second-storey addition with a basement finishing scope, often to create an in-law suite or self-contained lower-level apartment. Coordinating both scopes under a single contract reduces disruption and keeps the project on a unified timeline. Kopman Build manages structural underpinning where ceiling height requires it, as well as all plumbing, mechanical, and electrical work.
