Custom Homes in Vaughan
From estate lots around Kleinburg and Nashville to older bungalows in Maple, Woodbridge and Thornhill, we design and build custom homes on land you already own. Every project is quoted after we have walked the lot.
Building Your Own Home in Vaughan
Vaughan offers two very different kinds of custom home site. In the north and west, around Kleinburg, Nashville and the King Township line, lots are larger, the land rolls toward the Humber River valley, and a new home is planned around grading, mature trees and a long driveway. In Woodbridge, Maple and Thornhill, the typical project is a knock-down: an older house on a generous lot replaced with one sized for family life now.
Both kinds of site sit inside the Toronto and Region Conservation Authority's watershed. TRCA counts all of Vaughan's population within its jurisdiction, and where a lot touches a regulated valley, stream or wetland, the authority's permit has to be in hand before the City can issue a building permit. We check for that on the first visit.
Fees are the other early question. York Region charges $84,718 in development charges for a single detached home, on top of the City's own charge, and the timing of a demolition decides whether you pay it on a replacement house. We plan the order of permits so the credit for the house you are replacing is not lost.

What Shapes a Custom Home in Vaughan
These are the approvals and costs we plan for before the design is final.
TRCA Permits Come First
Building a new or replacement home in a TRCA regulated area needs a TRCA permit or clearance before the City can issue the building permit.
York Region Development Charges
The Region's charge for a single detached home is $84,718 as of May 21, 2026. It is calculated when the building permit is issued and paid at occupancy.
The 48-Month Demolition Credit
York Region credits a demolished house if it stood on the land within 48 months, counted from the date the demolition permit was issued.
City Charges Are Being Cut
Vaughan has announced a 50% cut to its residential development charges from March 30, 2026 to March 31, 2029, and a full waiver for projects that meet set construction milestones by October 31, 2027.
Lots Near the Valleys
On lots that slope toward a creek or ravine, the regulated area can decide the footprint, the grading and where the driveway runs.
What a Custom Home Costs in Vaughan
We do not publish a set price for custom homes, because the lot drives too much of the cost. As a benchmark, the Altus Group 2026 Canadian Cost Guide puts hard construction costs for custom-built single-family homes in the GTA at $500 to $1,130 per square foot. That range leaves out land, design, permits, development charges and HST.
Where a Vaughan home lands in that range depends on size, structure, finishes and the site, and a sloped estate lot costs more to build on than a flat infill lot. We review your lot and survey first, then quote. Our custom home cost guide breaks down the soft costs that sit on top.
Custom Homes We Build in Vaughan
Most Vaughan projects fall into one of these six groups.
Knock-Down Rebuilds
Replacing an older house in Woodbridge, Maple or Thornhill with a new home designed to the current zoning.
Estate Homes on Large Lots
Homes for the bigger lots of Kleinburg and Nashville, planned around slope, trees and the approach from the road.
Ravine and Valley Lots
Homes in the Humber and Don watersheds, where conservation authority approval can set the building envelope.
Multigenerational Homes
Layouts with a main-floor suite or a separate living area for parents or grown children.
Homes With a Secondary Unit
A legal additional unit planned into the design from the start, rather than squeezed in later.
Design-Build From Concept
One team for drawings, permits and construction, so the budget is tested against the design as it develops.
Homes and Interiors We Have Built
Interiors, kitchens and finishing details from our design-build work around the GTA.
