The Annex's streetscape of late Victorian and Edwardian homes from the 1880s–1910s demands a builder who understands heritage character requirements, structural age, and the neighbourhood's proximity to the University of Toronto — where zoning, noise, and site access each add complexity. Kopman Build has been navigating exactly these conditions for over 25 years.
The Annex is one of Toronto's most architecturally distinct and tightly regulated neighbourhoods. Its heritage character area designation means that any custom home project — whether a ground-up build, a semi-detached conversion back to single-family, or a whole-home restoration — requires more upfront coordination with the City than a standard Toronto renovation.
Kopman Build brings three neighbourhood-specific strengths to every Annex project. First, direct experience with Toronto's heritage overlay process and the design guidelines that apply to new construction and significant alterations in character areas. Second, a track record of managing semi-detached-to-single-family conversions, which are among the most common and complex project types in the neighbourhood. Third, deep familiarity with the active kitchen and bathroom renovation market in the Annex — where owners of century-old homes demand contemporary function without sacrificing the original character that makes the neighbourhood worth living in.
Dustin Kopman is directly involved in every project. That is not a marketing claim — it is the operating model we have run since 1999.

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 — including heritage overlay requirements specific to The Annex.
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.
Yes. The Annex is a heritage character area, which means demolition and new construction are subject to additional City of Toronto review and design guidelines. We have direct experience navigating heritage overlays, working with heritage consultants, and designing new builds that satisfy both the guidelines and the client's vision. Many projects in The Annex involve converting multi-unit properties back to single-family use, which carries its own permitting complexity we handle routinely.
Full restoration or gut-renovation of a late Victorian or Edwardian semi-detached or detached home in The Annex typically ranges from $500 to $900+ per square foot, depending on the extent of structural work, heritage requirements, and finish level. Ground-up custom builds on cleared lots start at similar figures. We provide a detailed pre-construction budget before any commitment is made.
Semi-detached-to-single-family conversions are common in The Annex and require careful structural assessment, zoning review, and coordination with the City to legally consolidate the units. We manage the full process — from initial feasibility through permit acquisition, structural work, and interior buildout — delivering a seamless single-family home from what was previously divided.
Absolutely. Kitchen and bathroom renovations are among the most active scopes in The Annex, and we integrate them naturally within larger custom home or whole-home renovation projects. Whether you are rebuilding a single kitchen or redesigning every wet room in a four-storey Victorian, we scope and manage it as a single coordinated project rather than a series of disconnected trades.
