The Annex is one of Toronto's most architecturally rich neighbourhoods — Late Victorian and Edwardian homes built between the 1880s and 1910s, many with original millwork, plaster walls, and century-old bones that demand genuine craft. Kopman Build has been renovating heritage homes like these across Toronto since 1999, with the patience and expertise the neighbourhood deserves.
Renovating in The Annex is not the same as renovating anywhere else in Toronto. These are heritage character homes — often semi-detached, frequently converted to multi-unit over the decades, and now increasingly being returned to their original single-family purpose. The work requires care, experience with older systems, and a contractor who understands what the City's heritage guidelines actually require in practice.
Three things define renovation work in The Annex: the heritage character area designation shapes what changes are permitted to exterior features; the demand for semi-detached conversions back to single-family means navigating change-of-use permits and restoring original layouts; and the active kitchen and bathroom renovation market here means homeowners expect a high standard of finish alongside the preservation of original detail. Kopman Build delivers all three.
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.
Full kitchen remodels in Victorian and Edwardian layouts — respecting original proportions while delivering modern function, storage, and appliance packages.
Primary suites, main baths, and powder rooms — complete gut-and-rebuild with careful attention to original tile patterns, cast iron plumbing, and period finishes.
Returning multi-unit semis to single-family use — removing non-original partitions, restoring layouts, updating systems, and managing City change-of-use permits.
Porch restoration, facade repairs, window replacement within heritage guidelines, and Heritage Permit management for properties in the conservation district.
Multi-phase, whole-house renovations managed as one coordinated project — one team, one schedule, one point of contact.
Crown moulding, hardwood floors, pocket doors, plaster walls, and original millwork — preserved, restored, or faithfully replicated where beyond saving.

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.
Kitchen renovations in The Annex typically run $65,000–$160,000+ given the older housing stock and the care needed around heritage finishes. Bathroom renovations range $28,000–$80,000. Converting a multi-unit semi back to a single-family home can range from $120,000 to $350,000+ depending on scope. We provide detailed pre-construction estimates before any commitment.
Many properties in The Annex fall within a Heritage Conservation District or carry individual heritage designations under the Ontario Heritage Act. This means alterations to exterior features — facades, porches, rooflines — require Heritage Permit approval from the City of Toronto in addition to standard building permits. Kopman Build manages both processes and works with heritage consultants when required.
Yes. Many Annex semis were subdivided into rooming houses or apartments over the decades and are now being returned to single-family use. The process involves removing non-original partitions, restoring staircase and hall layouts, updating electrical and plumbing to current code, and obtaining City permits for the change of use. Kopman Build has experience navigating all of this in older Edwardian and Victorian structures.
A kitchen renovation in an Annex home typically takes 10–16 weeks, often a little longer than newer builds because older homes frequently reveal surprises — knob-and-tube wiring, undersized drain stacks, or plaster walls that need careful handling. A bathroom renovation runs 5–10 weeks. We build contingency into our schedules and communicate any changes immediately.
Absolutely. Preserving and restoring original character details is one of the things that sets Annex renovations apart. We take extra care to protect existing hardwood floors, match original millwork profiles, restore or replicate plaster crown moulding, and keep functional pocket doors working. Where elements are beyond saving, we source period-appropriate replacements or commission custom millwork.
