Three Markhams, Three Kinds of Project

Markham is really several housing markets in one city. The historic villages — Unionville, Markham Village — hold older homes on established streets where additions must respect their context. The 1980s-and-90s neighbourhoods are prime rebuild-and-addition territory, with mature lots worth more than the houses on them. And the newer communities bring large basements ready for second suites. Each calls for a different drawing job, and we do all three.

Rebuilds & Additions on Mature Lots

When a Markham lot outvalues its house, owners rebuild or transform: full custom replacements, second storeys, major rear additions. We handle feasibility, design and the complete permit drawing set — including the measured existing drawings that addition projects require.

Custom Rebuilds

New homes on established lots

Second-Storey Additions

Transforming older two-storeys and bungalows

Heritage-Area Sensitivity

Designs that fit historic streets

Second Suites

Markham's newer homes offer deep, high basements that convert well to legal second units — and its rental demand is among the region's strongest. We design the suite and produce the permit drawings: separation, exits, services and the separate entrance.

Basement Suite Design

Self-contained legal units

Legalization

Existing units documented for compliance

Separate Entrances

Markham Building Permit Questions

We're in Unionville — does the historic area change anything?

Design in and around heritage districts calls for more care with massing, materials and streetscape fit, and municipal review can involve additional considerations. We design with that context in mind and confirm your property's specific requirements at the start.

Which Thornhill side is Markham's?

Thornhill straddles Yonge Street: the east side is Markham, the west side is Vaughan. If your property is on the Markham side, your application goes to the City of Markham — and we prepare drawings for it.

Rebuild or renovate — how do we decide?

By the numbers and the structure. We assess what the existing house can support and what the lot allows, and give you a straight comparison before design begins. The consultation is free.
