Whitby's suburban housing stock — from heritage downtown properties to the newer builds spreading across Durham Region — is full of untapped potential. Kopman Build brings 25 years of craft and discipline to Whitby homeowners who want renovations done properly, on schedule, and with no surprises.
Whitby is one of Durham Region's fastest-growing renovation markets. The town's mix of heritage downtown character and expansive post-2000 suburban subdivisions means renovation scopes vary widely — from restoring original details in a century home to completely reimagining the layout of a builder-grade house that no longer fits how a family lives.
Kopman Build has managed complex projects across the GTA and Durham Region since 1999. Dustin Kopman founded the company after growing up working in his family's construction firm, G&G Enterprise. That hands-on background means every Whitby project is led by someone who understands the craft — not just the contract.
Full kitchen remodels from layout changes to custom cabinetry, countertops, and appliance packages — designed for how Whitby families cook and gather.
Primary suites, main baths, ensuites, and powder rooms — complete gut-and-rebuild or targeted upgrades that make a real difference.
Legal secondary suites, family rooms, home offices, and full basement renovations built to Ontario Building Code standards.
Rear additions, second-storey additions, and garage conversions designed to integrate seamlessly with your existing structure and neighbourhood.
Ground-up custom homes on Whitby infill and subdivision lots — design-build delivery from planning through construction and handover.
Multi-phase, whole-house renovations managed as one coordinated project — one team, one schedule, one point of contact.
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.
Kitchen renovations in Whitby typically run $55,000–$140,000+. Bathroom renovations range $22,000–$65,000. Whole-home renovations in Whitby's growing suburban market can range from $130,000 to $450,000+ depending on scope and finish level. Kopman Build provides detailed pre-construction estimates before any commitment.
Yes. Structural renovations, additions, basement conversions, and most significant interior alterations in Whitby require permits from the Region of Durham or the Town of Whitby Building Division. Kopman Build manages the full permit process — applications, required engineering, inspections, and final sign-offs.
Absolutely. Much of Whitby's housing stock consists of 1990s–2010s builder-grade suburban homes with significant upgrade potential. We specialize in transforming these homes — opening layouts, upgrading kitchens and baths, finishing basements, and adding second storeys — to reflect how families actually live today.
Yes. Whitby is one of Durham Region's most active markets for custom home construction, with infill lots and new subdivisions offering opportunities for ground-up builds. Kopman Build's design-build capabilities cover everything from site planning and architectural coordination through to construction and handover.
A kitchen renovation typically takes 8–12 weeks. A bathroom 4–8 weeks. A full basement finish 10–16 weeks. Larger whole-home or addition projects can run 6–18 months. We build realistic schedules at the outset and maintain them with full-time site supervision throughout.
