The Annex is one of Toronto's most architecturally significant neighbourhoods — a dense grid of late Victorian and Edwardian homes built from the 1880s through the 1910s, many semi-detached and set close to the University of Toronto campus. Kopman Build brings the heritage sensitivity, structural experience, and full general contracting capability these century homes demand.
Working in The Annex as a general contractor means working with buildings that carry more than a century of layered renovations, original masonry, and wood-frame construction that predates modern building codes. The neighbourhood's heritage character area designation adds a further layer — one that requires a contractor who understands both the City's review process and the craft involved in preserving what makes these homes worth keeping.
The Annex is also an active market for semi-detached conversions back to single-family use, and for high-quality kitchen and bathroom renovations driven by a well-educated, detail-oriented ownership base that lives close to U of T. Kopman Build has managed projects across all three of these categories since Dustin Kopman founded the company in 1999 — bringing owner-direct engagement and institutional-grade project management to every job.
Our trade network has been built and maintained over 25 years. That means reliable access to the masonry, millwork, and heritage-finish specialists that Annex renovation projects consistently require — not whoever happens to be available that week.

The Annex is a heritage character area with a dense stock of late Victorian and Edwardian homes built between the 1880s and 1910s. A general contractor working here must coordinate heritage sensitivity with modern building code compliance — navigating City of Toronto heritage guidelines, managing the structural realities of century-old masonry and timber framing, and sourcing period-appropriate finishes where required. Kopman Build has deep experience managing exactly this type of project.
Yes. Many Annex semi-detached homes were subdivided into multi-unit rentals over the decades and are now being converted back to single-family use. This typically involves structural work to remove non-original partitions, plumbing and electrical reconfiguration, and a building permit from the City of Toronto. Kopman Build manages the full scope — permits, trades, and delivery — as a single accountable general contractor.
Kitchen and bathroom renovation costs in The Annex vary depending on scope and the condition of the existing structure. Older homes often carry surprises — outdated knob-and-tube wiring, galvanized plumbing, or uneven subfloors — that affect budget. Kopman Build provides detailed line-item estimates with clearly identified allowances and contingencies before any work begins, so there are no hidden surprises at handover.
Yes. Kopman Build manages all permit applications with the City of Toronto as part of our general contracting service. For Annex properties that fall within a heritage character area or are individually listed, we also coordinate any required heritage review submissions. Permits are not optional: unpermitted work on a century home creates serious liability at the time of sale.
