The Kingsway's 1920s–1940s custom homes on generous ravine-adjacent lots are among Etobicoke's most architecturally distinctive — and a second storey addition, done correctly, can double your living space while preserving the character that defines the neighbourhood. Kopman Build has been managing full custom additions across Etobicoke's premium enclaves since 1999.
Adding a second storey to a Kingsway home is not a standard construction project. The neighbourhood's housing stock — Tudor revivals, Georgian colonials, and Craftsman bungalows built between the wars on deep, landscaped lots — demands a level of craft and architectural sensitivity that most contractors cannot deliver. Getting the roofline, masonry, window proportions, and exterior detailing right requires experience with heritage-adjacent work and a genuine commitment to quality over speed.
Kingsway properties also carry particular complexity: many sit close to the Humber River ravine system, introducing conservation authority jurisdiction, grading constraints, and tree protection requirements that affect how a second storey addition is permitted and built. Kopman Build has navigated these approvals repeatedly and manages the full process — design, engineering, permits, and construction — under one roof.
Dustin Kopman founded the company in 1999 after growing up in construction through his family's firm, G&G Enterprise. Every Kingsway project is managed by someone who understands the craft at a technical level, not just the sales process.

A second storey addition on a Kingsway home typically runs $350,000–$700,000+, depending on the existing structure, lot constraints, and finish level. Kingsway's heritage-adjacent 1920s–1940s homes often require additional structural work and custom detailing to match the original character — both factors that affect the final cost. Kopman Build provides a detailed line-item estimate before any commitment.
Yes. All second storey additions in Etobicoke require City of Toronto building permits. Many Kingsway properties — particularly those on larger ravine-adjacent lots — may also require a Committee of Adjustment minor variance if the proposed addition exceeds zoning height or setback limits. Kopman Build manages all permit applications, zoning reviews, and approval coordination on your behalf.
From initial consultation to occupancy, a second storey addition in Kingsway typically takes 14–20 months. Permitting and design usually account for 4–8 months before a shovel goes in the ground; construction itself takes 8–14 months. We set a realistic schedule from day one and communicate weekly throughout the project.
Absolutely. The Kingsway's housing stock — primarily custom-built homes from the 1920s through the 1940s in Tudor, Georgian, and Craftsman styles — demands architectural sensitivity. Kopman Build works with experienced designers to ensure that new second-storey additions respect rooflines, window proportions, masonry, and exterior cladding so the finished result reads as original, not as an addition.
