Humber Valley's 1950s and 1960s homes — set on generous ravine and golf-course lots — call for a renovation contractor who understands both the character worth keeping and the systems that need replacing. Since 1999, Kopman Build has delivered full-scope renovations across Etobicoke's most coveted addresses with the precision this premium market demands.
Ravine lots along the Humber River add both beauty and complexity. Work near the ravine edge involves Toronto and Region Conservation Authority approvals, careful grading, and erosion controls that an inexperienced contractor can easily mismanage. Kopman Build has navigated TRCA processes on multiple Etobicoke projects and knows how to move these approvals efficiently without surprises.
The neighbourhood's heritage character — brick ranch bungalows, split-levels, and two-storeys with mature tree canopies — means clients expect renovations that honour original proportions on the exterior while delivering fully contemporary interiors. We excel at that balance. Full-scope projects here commonly involve structural upgrades, complete mechanical and electrical overhauls, and high-end finish packages that justify the neighbourhood's position as one of Etobicoke's most sought-after communities.
Dustin Kopman founded the company in 1999 after growing up in construction through his family's firm, G& G Enterprise. Every Humber Valley project is managed by someone with genuine craft knowledge — not a salesperson handing off to an unknown crew.

Humber Valley is a premium renovation market. Kitchen renovations typically run $80,000–$200,000+. Bathroom renovations range $30,000–$90,000. Full-scope whole-home renovations on the area's larger 1950s–60s homes commonly reach $300,000–$700,000+. We provide detailed pre-construction estimates before any commitment.
Yes. Properties backing onto the Humber River ravine system fall under Toronto and Region Conservation Authority (TRCA) jurisdiction in addition to standard City of Toronto building permits. Additions, grading changes, and landscaping near the ravine edge require TRCA approval. Kopman Build manages the full approval process including TRCA applications, erosion and sediment controls, and City permits.
Post-war homes in Humber Valley often present hidden conditions — knob-and-tube wiring, galvanized plumbing, asbestos-containing materials, and undersized structural members. We build realistic contingency into every schedule. A kitchen renovation typically takes 10–16 weeks. A full basement finish 12–18 weeks. Whole-home renovations run 8–20 months depending on scope and permit timelines.
Yes — this is one of our specialties in Humber Valley. We work with architects and clients to retain period-appropriate exterior profiles, masonry, and proportions while fully modernizing interiors. We understand how to respect the neighbourhood's architectural character while delivering contemporary finishes and updated mechanical, electrical, and structural systems.
Yes. Rear additions, second-storey additions, and side additions on irregularly shaped or ravine-adjacent lots require careful site analysis, TRCA coordination where applicable, and setback reviews with the City of Toronto. Kopman Build has experience navigating these constraints and works with experienced architects to maximize what is achievable within the lot's specific conditions.
