Birchcliff Heights is built on some of Scarborough's most solid housing stock — 1940s and 1960s brick bungalows along the Birch Cliff Ave corridor that are structurally well-suited to rear and second-storey additions. Kopman Build has been expanding homes like these across Scarborough and the GTA since 1999, adding space and value without compromising the character of the neighbourhood or the integrity of the existing structure.
The established brick bungalows of Birchcliff Heights are a genuine asset for homeowners considering an addition. The mid-century construction is typically sound, with good foundations and load-bearing walls that make structural integration more straightforward than in newer, wood-frame homes. A well-executed rear or second-storey addition here adds significant living space at a fraction of the cost of upsizing in a neighbourhood where Scarborough Bluffs proximity commands strong resale values.
Lots along and near Birch Cliff Ave tend to be generously sized by Toronto standards, giving rear additions meaningful room to work with. That said, zoning setbacks and lot coverage limits still apply, and older homes often carry legacy electrical, plumbing, or insulation conditions that are best addressed as part of the addition scope. Kopman Build assesses all of this upfront, so costs and timelines are grounded in the actual state of your property.
Dustin Kopman founded the company in 1999 after growing up working in construction through his family's firm, G& G Enterprise. Every project is managed by someone who understands the craft — not just the sales pitch.

Home addition costs in Birchcliff Heights are broadly consistent with Scarborough and Toronto ranges: a single-storey rear addition typically runs $200,000–$380,000+ depending on size and finish. A second-storey addition on a 1940s–1960s bungalow runs $300,000–$580,000+. The solid brick construction common to the neighbourhood is a structural asset, but older homes may require foundation or electrical upgrades as part of the scope. We provide a detailed line-item estimate before any commitment.
Yes — second-storey additions on Birchcliff Heights bungalows are one of our most common project types in the area. The mid-century brick stock along and near Birch Cliff Ave is generally well-built and structurally sound, which makes it well-suited to second-storey additions. Kopman Build will assess your existing structure, foundation, and lot setbacks before preparing an estimate. We manage all engineering, permits, and construction.
Yes. All home additions require a building permit from the City of Toronto. Depending on the scope and whether your proposed addition exceeds zoning setbacks or lot coverage limits, a Committee of Adjustment minor variance application may also be required. Birchcliff Heights properties are subject to Toronto's zoning by-law 569-2013. Kopman Build manages the full permit and approval process from application through sign-off.
A typical rear addition in Birchcliff Heights takes 6–10 months from permit approval to completion. A second-storey addition takes 8–14 months. City permit processing adds 3–6 months before construction begins; a minor variance application adds further time. We give you a realistic total timeline at the start of the project — not optimistic numbers that shift later.
