The Junction's Victorian and Edwardian homes sit on sought-after lots in one of Toronto's fastest-gentrifying neighbourhoods — a second storey addition is the single most effective way to double your square footage and capture that value. Kopman Build has been building second storey additions in Toronto since 1999, managing every step from structural assessment and permits to finished construction.
The Junction is a former industrial neighbourhood that has undergone significant transformation. Its existing housing stock — predominantly Victorian and Edwardian semis and detached homes — represents strong renovation arbitrage: properties are being gut renovated and substantially upgraded across the neighbourhood, and second storey additions are one of the most active project types. Buyers are paying for finished, expanded square footage, and owners who invest well capture that premium.
Adding a second storey to an older Junction home is technically demanding. Original framing and foundations often need reinforcement; heritage character on the streetscape may need to be respected; and tight lots create logistical complexity during construction. Kopman Build has managed all of these conditions before, and our pre-construction process ensures the full scope is understood — structurally, regulatorily, and financially — before any commitment is made.
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 and holds themselves accountable to the outcome — not just the contract.
Engineering review of existing foundations and framing to determine what reinforcement is required before a second floor is added.
Complete new second floors on Junction bungalows and single-storey homes — bedrooms, bathrooms, and primary suites fully designed and built.
Targeted additions — a primary bedroom suite, an extra bathroom, a home office — where only part of the footprint is raised.
Full management of City of Toronto building permits, Committee of Adjustment applications, and all consultant coordination.
Second storey additions often prompt a main floor renovation. We coordinate both scopes so the whole project is executed once, efficiently.
Designing second storeys that respect the Victorian and Edwardian character of The Junction streetscape — aesthetically and regulatorily.

Structured handover with all documentation, warranties, and a 12-month attendance window post-completion.
A full second-storey addition in The Junction typically runs $350,000–$650,000+ depending on the footprint, existing structure, and finish level. The Victorian and Edwardian homes common to the neighbourhood often require structural upgrades to support a new floor — this is factored into our pre-construction estimate so there are no surprises mid-project.
In most cases, yes — but the existing structure needs a proper engineering assessment first. Many older homes in The Junction have foundations and framing that require reinforcement before a second floor is added. Kopman Build commissions a structural engineer as part of pre-construction planning so the scope and cost are fully understood before you commit.
Yes. A second-storey addition in Toronto requires a building permit from the City, and depending on the lot and zoning, a minor variance through the Committee of Adjustment may also be required. The Junction falls under Toronto's zoning bylaws, and Kopman Build manages the full permit and approval process on your behalf.
From initial consultation to final occupancy, expect 14–20 months in total. Permitting and approvals typically take 4–8 months, and construction runs 8–14 months after permits are in hand. Neighbourhood-specific factors in The Junction — such as tight lots and older utility connections — are accounted for in our timeline from day one.
