Markham — City of Markham Building Standards
Custom Home Construction in Markham
Markham custom building spans two worlds a few kilometres apart. On Unionville’s heritage streets, new homes must earn their place beside 19th-century neighbours through Heritage Markham review — massing, materials and rooflines matched to the district plan. On Cachet and Angus Glen estate lots, the canvas is wider: 80-foot frontages where limestone, brick and slate compositions can breathe. We build fluently in both.
The City has also made Markham one of Ontario’s most energy-forward municipalities, and our builds lean into that trajectory: envelope-first design, triple glazing where orientation demands it, air-source heat pumps, and net-zero-ready assemblies that cost modestly more today and outperform for decades. Buyers notice; so do appraisers.
Every home is delivered under one superintendent with weekly reporting, HCRA licensing and Tarion warranty — the same playbook behind our estates across the GTA.

Why Markham builds carry our name
Approval fluency is local currency. Heritage Markham reviews new construction within the Unionville and Markham Village districts against detailed guidelines, and Cathedraltown carries its own architectural controls administered through the community’s control architect. We design to those frameworks from the first massing study — our submissions arrive speaking the reviewers’ language, and it shows in the approval timelines.
On estate lots, our advantage is delivery depth: in-house exteriors crews for the auto court and landscape, millwork through our own shop, and trade teams who have run 6,000-square-foot builds together for years. One accountable schedule carries excavation through landscaping — no seasonal gap where the house sits finished behind a dirt yard.
New-build approvals and standards in Markham
A Markham custom build requires demolition and building permits through City of Markham Building Standards — complete house applications are typically processed within about ten business days, a genuine regional advantage. Variances for massing beyond zoning go to the Committee of Adjustment (two to four months), and lots near Rouge tributaries may need TRCA clearance.
Two local layers shape design: heritage review for new construction in the Unionville and Markham Village districts, and architectural control approval in Cathedraltown before permit submission. Markham’s sustainability standards also nudge new homes toward net-zero-ready performance — a direction we design to by default rather than retrofit later.

Client Words — Markham
“Heritage approval, permits, construction — eleven months from lot purchase to framing. Everyone told us Unionville would take years.”
“Our hydro bills embarrass the neighbours and the house is silent in wind. Building energy-forward was their idea, and it was the right one.”
