The Beaches is a neighbourhood of early 20th-century cottages and lakefront family homes — a housing stock that rewards thoughtful additions and punishes shortcuts. Kopman Build has built home additions across Toronto since 1999, and we know how to expand a Beaches cottage without losing the character that makes the neighbourhood worth staying in.
Young families throughout The Beaches face a familiar decision: move to a larger property or invest in the home they already love, steps from the boardwalk and the lake. An addition is often the better answer — but it requires a contractor who understands the neighbourhood's tight lots, older structural systems, and the streetscape character the City actively protects.
Kopman Build brings three things that matter here. First, we assess existing cottage-era foundations and framing before finalising any design — surprises mid-construction are how Beaches addition budgets go sideways. Second, we manage Committee of Adjustment applications when tight setbacks require a minor variance, which is common on the narrower lots east of Woodbine. Third, we design additions that look like they belong — not like an extension bolted onto a cottage.
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.
Single-storey and multi-storey rear additions that extend your living space and integrate structurally with the existing cottage or family home.
Full second-storey additions on Beaches bungalows and cottages — double your living space without leaving the neighbourhood.
Toronto laneway suites designed and built to City of Toronto guidelines — where laneways behind Beaches properties meet eligibility requirements.
Garden suites in rear yards as permitted under Toronto's expanded as-of-right zoning for properties with sufficient lot depth.
Converting attached or detached garages into living space, home office, or income-generating rental units.
Smaller additions — mudrooms, sunrooms, bump-outs — designed to integrate cleanly with the existing cottage-style architecture.
We visit your property, listen to your goals, and document the project in writing — scope, budget, and timeline.
A detailed line-item estimate with allowances and contingencies, so you know the number before committing.
We manage all permit applications, engineering consultants, and approvals — including Committee of Adjustment applications when lot conditions require a minor variance.
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.
Home addition costs in The Beaches typically run $220,000–$420,000+ for a single-storey rear addition and $320,000–$620,000+ for a full second-storey addition. The tight lots and cottage-era construction common in the neighbourhood can add complexity — older foundations and load-bearing walls need careful structural assessment. Kopman Build provides detailed pre-construction estimates before any commitment.
Yes. All home additions in The Beaches require building permits from the City of Toronto. Depending on lot coverage and setbacks — which are frequently tight on the narrower lots throughout the neighbourhood — a Committee of Adjustment minor variance application may also be required. Kopman Build manages the full permit and approval process from start to finish.
Yes, and it is one of the most common scopes we handle in the neighbourhood. The Beaches has a large stock of early 20th-century cottages and bungalows occupied by growing families who want to stay close to the boardwalk and lake without buying a larger property. A full second-storey addition typically takes 8–14 months from permit approval to completion. We assess the existing structure thoroughly before finalising the design.
The Beaches has a distinct architectural character — board-and-batten siding, covered porches, dormers, and modest setbacks that give the street its lakefront-cottage feel. Kopman Build designs additions to read as intentional extensions of the original home rather than conspicuous additions. We coordinate with architects experienced in Beaches-area heritage character and work within the City's urban design guidelines to protect the streetscape.
