Forest Hill's 1920s–1950s custom homes — from the stately properties of Forest Hill Village North to the well-proportioned semis near South Forest Hill's subway corridor — are ideal candidates for a full second-storey addition that doubles living space without sacrificing the neighbourhood's character. Kopman Build has been building second-storey additions in Toronto since 1999, and we bring that depth of experience to every Forest Hill project.
Forest Hill is one of Toronto's most demanding renovation markets. Clients here expect premium finishes, minimal disruption, and a contractor who understands what it means to work on a custom home — not a production build. Kopman Build has operated at that standard since 1999, and every second-storey addition we deliver is managed by a principal who knows the craft, not just a project manager running a checklist.
Second-storey additions in Forest Hill require particular care. The existing 1920s–1950s structures often feature traditional masonry construction, timber framing, and original plaster interiors that must be protected throughout the build. We manage structural assessment, permit coordination with the City of Toronto, and all consultant relationships — architects, engineers, and heritage consultants where required — so you have a single accountable point of contact from first meeting to final inspection.
South Forest Hill's proximity to the Eglinton subway makes finished square footage especially valuable. In Forest Hill Village North, where lot sizes are larger and custom architecture is the norm, a well-executed second storey can be transformational — adding bedrooms, a primary suite, or a private study while preserving the home's street presence.
Complete second-floor addition over an existing single-storey bungalow or partial-storey home — new floor structure, exterior walls, roof, and full interior fit-out.
Engineering review of existing foundations, load-bearing walls, and framing to confirm capacity before design is committed — essential for 1920s–1950s Forest Hill homes.
Full management of City of Toronto building permit applications, including architectural drawings, structural engineering, and any Committee of Adjustment submissions.
Second-storey additions focused on a primary bedroom suite with ensuite bath, walk-in closet, and private sitting area — a common goal in Forest Hill.
Adding multiple bedrooms and a home office or library on a new second floor — ideal for Forest Hill families who want to stay in the neighbourhood without upsizing through a sale.
Coordinating the second-storey addition with a simultaneous main-floor renovation so the entire home is upgraded in a single, phased construction project.
We visit your Forest Hill 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, structural and architectural consultants, and City approvals — nothing falls through the cracks.
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.
Second storey additions in Forest Hill typically run $400,000–$750,000+, reflecting the neighbourhood's premium custom home standard and the complexity of adding a full floor to a 1920s–1950s structure. Cost depends on existing foundation and roof condition, square footage, and the finish level expected in Forest Hill Village. Kopman Build provides a detailed line-item estimate before any commitment.
Yes. A second storey addition in Forest Hill requires a City of Toronto building permit, structural engineering drawings, and typically an architect's involvement. Many Forest Hill lots are also subject to Ontario Heritage Act considerations or neighbourhood character overlays, which can affect massing and design. Kopman Build manages all permits, approvals, and consultant coordination.
From initial design to occupancy, most Forest Hill second storey additions take 12–18 months. Permit approval alone can take 4–6 months. Construction of the addition — removing the existing roof, adding the new floor structure, and completing interior fit-out — typically runs 8–12 months. We provide a project-specific timeline at the pre-construction stage.
Many Forest Hill homes built between the 1920s and 1950s have substantial masonry or poured-concrete foundations that can support a second storey with engineered reinforcement. A structural engineer assesses the existing foundation, exterior walls, and load path before design begins. Kopman Build coordinates this assessment as part of our pre-construction process — no guesswork, and no surprises once construction starts.
Kopman Build builds second-storey additions across Forest Hill and Toronto. No-obligation consultation — we come to your property.
