Outdated Markham Home? We Modernize It on a Fixed Price
These are the problems most homeowners face. Our fixed-price design-build model is built to solve them.
Budget Blowouts
Most renovations creep 30% over budget through vague "allowances". We replace estimates with a firm, fixed-price contract, so the number you approve is the number you pay.
Outgrown, Outdated Layouts
Cramped, closed-off rooms make a home you love feel like one you have outgrown. Our design-build team reworks the floor plan around how your family actually lives today.
Juggling Unreliable Trades
Coordinating a designer, a contractor, and a dozen trades is exhausting. We give you one accountable team and a single point of contact from first sketch to final clean-up.

Why Markham Homeowners Choose Us
Subdivision Renovation Specialists
Markham's planned subdivisions and clear road network make site logistics predictable. Our crews reach Unionville, Cornell, and Berczy Village via Highway 407, Highway 404, and Markham's main arterials, keeping deliveries and trade scheduling efficient.
Markham renovations are permitted through the City of Markham, which runs its own application and inspection process. We know that process and handle it for you - drawings, permit applications, and inspections - so the build stays on schedule from start to finish.
Markham Homes We Know Well
Markham's established 1980s and 1990s subdivisions - Unionville, Cornell, Berczy Village, and Milliken - are now reaching the age where they are due for modernization. These homes typically feature closed-plan main floors, formal rooms that go unused, and kitchens separated from family living areas.
We specialize in opening those layouts up, removing walls to connect the kitchen, dining, and living spaces, and reworking floor plans for the way families live today. Markham's mix of detached homes and condos also brings multi-generational layout needs, and our fixed-price design-build approach delivers those updates without budget surprises.

“We interviewed four contractors. Whole House Renovation was the only one who planned every detail before construction. The pre-construction work made the build itself almost stress-free.”
“They managed all of it - approvals, scheduling, the lot. Beautiful result, and the price never changed.”
