Custom Home Construction in Markham
As a custom home builder, we manage your project from first site visit through occupancy, with architect, interior designer, and construction manager sharing one plan. Unionville’s historic Main Street is a designated heritage conservation district requiring extra design review, while Thornhill and Berczy Village offer more conventional teardown-and-rebuild opportunities on larger, older lots — we identify which set of considerations applies to your specific property before any design work begins. See our Custom Home Construction page for our full design-build process.

How We Handle Permits & Approvals in Markham
We confirm whether your property falls within the Unionville Heritage Conservation District before finalizing any design, since properties there require additional heritage review to confirm compatibility with the area’s protected character, on top of standard zoning and building permit approval. For properties elsewhere in Markham, we manage the standard site plan and building permit process, confirming zoning compliance against the applicable by-law before construction begins.
