Renovation in Markham
Markham packs an unusual range of housing into one municipality. Unionville's heritage main street area has genuinely old homes. Newer neighbourhoods like Cornell and Cathedraltown are recent, higher-density builds. In between, you've got decades of subdivision growth from the 70s through the 2010s. Each generation needs its own renovation approach.
Unionville heritage streets
Some of the oldest housing in York Region, with heritage designation considerations affecting what changes are permitted.
Newer high-density neighbourhoods
Cornell and similar areas have smaller lots and closer setbacks, which changes how additions and exterior work get planned.
Multi-generational family homes
Markham has a high rate of homes renovated for multi-generational living, with secondary kitchens and separate entrances being common requests.

Heritage designation limiting exterior changes in Unionville
Homeowners in Unionville's heritage conservation district sometimes plan an exterior renovation without realizing the changes need heritage committee approval first, which can affect material choices and even window styles.
We check heritage designation status before designing exterior changes
For any Unionville property, we confirm whether it falls within the heritage conservation district before finalizing exterior plans. That way the design already respects what the committee will actually approve.

Markham renovation questions
Does my Unionville home need heritage approval for exterior changes?
If it's within the heritage conservation district, likely yes. We check this before finalizing any exterior renovation plans.
Can you design a multi-generational layout with a separate entrance?
Yes, this is a common request in Markham and we've built several secondary kitchen and private suite setups.
Do newer Markham neighbourhoods have tighter renovation restrictions?
Setbacks are often closer in newer areas like Cornell, which changes how much room we have for additions. We plan around it.
Do you pull City of Markham permits?
Yes, for any work requiring them.
