Leslieville's 1890s–1920s worker cottages and Victorian homes are some of Toronto's most characterful — and most demanding — renovation canvases. Kopman Build brings over 25 years of full gut renovation and custom build experience to the east side, delivering complete transformations on detacheds, semis, and row houses with the discipline this housing stock requires.
Leslieville is a rapidly gentrifying east-side neighbourhood where buyers are paying top dollar for century-old homes and immediately investing in their transformation. That combination — high acquisition cost, high renovation ambition, complex underlying structure — demands a builder who has done this before, properly.
The Victorian detacheds and semis that define Leslieville were built between the 1890s and 1920s. Behind their original brick facades, most carry knob-and-tube wiring, galvanized supply plumbing, and timber framing that needs careful assessment before any finishing work begins. A full gut renovation here is not a cosmetic exercise — it is a structural and mechanical overhaul wrapped in careful design execution.
Kopman Build was founded by Dustin Kopman, who grew up working in construction through his family's company G & G Enterprise. He has managed projects across Toronto's east end for decades and understands this housing stock at a level that matters when the walls come off.
Feasibility assessment, lot evaluation, architect and consultant coordination before a single dollar is committed.
Itemised estimates with allowances and contingencies — cost certainty before breaking ground.
Full permit management across Toronto Building, including heritage reviews and Committee of Adjustment where needed.
Complete structural and mechanical overhaul of Victorian-era homes — done right, with no shortcuts to legacy systems.
High-demand scopes executed within the context of a full build or as standalone projects — the same care either way.
Structured handover with all drawings, warranties, and manuals. 12-month attendance window post-completion.
We listen first. A site walk and discovery session to define the project in writing — goals, constraints, budget, and timeline.
Working with your architect or ours, we develop a scope of work, construction schedule, and complete permits strategy.
A line-by-line estimate with allowances, contingencies, and a clear path to a fixed-price contract.
Full-time supervision, weekly client updates, and open-book cost tracking throughout the build.
Structured handover and a 12-month attendance window. The relationship doesn't end at move-in.
A complete gut renovation of a Leslieville Victorian detached or semi typically ranges from $350,000 to $750,000+ depending on square footage, structural scope, and finish level. Homes from the 1890s–1920s often carry hidden costs — knob-and-tube wiring, galvanized plumbing, and settling foundations — that require remediation before finishing work begins. We provide detailed pre-construction budgets that account for these contingencies before you commit.
Most full-scope gut renovations in Leslieville run 8–16 months from permit issuance to occupancy. Older Victorian and worker cottage stock frequently requires structural remediation, new mechanical systems, and underpinning — work that must be sequenced carefully. We build realistic schedules before breaking ground and report against them weekly.
Yes. We manage the full permit process with the City of Toronto, including building permits, heritage consultations where applicable, and any Committee of Adjustment applications for additions or setback variances. Leslieville's rapid gentrification has intensified scrutiny on alteration permits — our experience with Toronto Building navigates that efficiently.
Yes, and it is one of the most common scopes we execute in the east end. Rear additions and second-storey additions on Leslieville semis and detacheds require careful structural integration with existing 100-year-old framing. We coordinate with structural engineers experienced in legacy Toronto construction to ensure the work is done correctly and durably.
