Yorkville's mix of 19th-century Victorian row houses and boutique townhomes makes second storey additions a natural way to double your living space without leaving one of Toronto's most coveted addresses. Kopman Build has been managing structural additions on established Toronto housing stock since 1999 — including the heritage-sensitive and party-wall work that Yorkville projects often require.
Yorkville's Victorian row houses sit on narrow lots with shared party walls, shallow front setbacks, and — in some cases — heritage designation or proximity to the Heritage Register. Adding a second storey here demands more than standard construction experience: it requires a contractor who understands how the City's heritage review process intersects with building permits, and who has the structural relationships to assess century-old foundations honestly before design begins.
Kopman Build brings three neighbourhood-specific strengths to every Yorkville second storey addition. First, we engage structural engineers at the consultation stage — not after drawings are done — so structural constraints inform the design from day one. Second, we have managed permit submissions requiring heritage staff coordination and Committee of Adjustment variances in Toronto's established neighbourhoods, and we know how to keep those processes from derailing a project timeline. Third, Yorkville's upscale retail district and density of luxury properties mean tradespeople and deliveries must be carefully scheduled to respect neighbours and the street — our site management protocols are built for exactly this environment.
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.

Many of Yorkville's 19th-century Victorian row houses can accommodate a second storey addition, but structural assessment is essential. Kopman Build engages a structural engineer early to evaluate the existing foundation and party walls before any design commitment. We have successfully added full second storeys to similar heritage row house stock throughout Toronto's established neighbourhoods.
Portions of Yorkville fall within heritage conservation districts or are adjacent to properties on the Heritage Register, which can trigger additional review at the City. Kopman Build assesses heritage implications as part of pre-construction due diligence and coordinates with City heritage staff where required to secure approvals without unnecessary delays.
A full second storey addition in Yorkville typically runs $375,000–$650,000+ depending on the existing structure, floor area added, and finish level. Yorkville projects often carry premium finish expectations given the neighbourhood's character, and heritage or party-wall considerations can add to structural costs. Kopman Build provides a detailed pre-construction estimate before any commitment.
From initial consultation through final occupancy permit, expect 14–20 months for a second storey addition in Yorkville. Permitting alone — including any heritage review or Committee of Adjustment process — typically takes 4–8 months. Construction runs 8–12 months after permit issuance. We give you a complete, realistic timeline at the outset so there are no surprises.
