Princess-Rosethorn's 1950s and 1960s custom bungalows sit on some of the most generous lots in Etobicoke — an ideal canvas for full renovations, substantial rear additions, and second-storey builds. Kopman Build has served this premium Etobicoke enclave since 1999, bringing owner-direct general contracting and a deep trade network to every project.
Princess-Rosethorn is one of Etobicoke's most sought-after addresses, and the projects here reflect that. The neighbourhood's mid-century bungalows on oversized lots attract homeowners who want to significantly expand — not just refresh — and that demands a general contractor with the experience to manage complex additions, structural work, and premium finishes simultaneously.
Kopman Build brings three things that matter most in this market: deep Etobicoke roots dating back to 1999, a trade network capable of delivering at the quality level these homes deserve, and a principal-led model where Dustin Kopman remains personally accountable from permit application to final walkthrough. Large lots support major additions here — and we have the experience to build them properly.
We also understand the planning process in Toronto. Zoning setbacks and lot coverage rules in Princess-Rosethorn often require a Committee of Adjustment application alongside a building permit. We manage both, so there are no surprises mid-project.
Complete gut renovations of Princess-Rosethorn's mid-century bungalows — updated structure, mechanical, and finishes throughout.
Rear additions, second-storey builds, and side extensions that take full advantage of the neighbourhood's generous lot sizes.
Demolition and new construction on existing lots — maximizing the land value that Princess-Rosethorn's premium Etobicoke location commands.
Full project management from permit to handover — one GC, one point of contact, consistent accountability throughout.
A vetted Etobicoke trade network covering structural, mechanical, electrical, and premium finish work built over 25 years.
Integrated design-build engagements coordinating architecture, engineering, and construction as a single managed scope.
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 — 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.
Princess-Rosethorn's 1950s and 1960s custom bungalows on generous lots are well suited to full gut renovations, rear and second-storey additions, and complete custom rebuilds. A general contractor manages all scopes — permits, structural, mechanical, and finish trades — under a single accountable contract. Kopman Build has delivered all of these project types in Etobicoke.
Yes. Any structural addition — rear, side, or second storey — requires a building permit from the City of Toronto. In Princess-Rosethorn, projects may also require a Committee of Adjustment application if the proposed addition exceeds zoning setback or lot coverage limits. Kopman Build manages the full permit process, including consultant coordination and City submissions.
Given the premium Etobicoke market and the scale of projects typical in Princess-Rosethorn, full renovations generally start at $300,000 and major additions — including second-storey builds — commonly range from $400,000 to well above $700,000 depending on scope and finishes. Kopman Build provides a detailed line-item estimate before any commitment is made.
Kopman Build has operated in Etobicoke since 1999 and understands the expectations of Princess-Rosethorn homeowners: careful site management, premium trades, and a finished product that reflects the neighbourhood's standards. Dustin Kopman is personally involved in every project, and we maintain an owner-direct model throughout construction — not a hand-off to a site supervisor you've never met.
