Milton's boom built whole communities of newer homes. Hawthorne Village, Beaty, Clarke and Willmott basements are typically tall, dry and ready to finish into theatres, gyms and family space, while Old Milton's mature streets reward moisture-first construction.
For one of Canada's youngest, fastest-growing towns, a finished basement is the affordable way to add a floor of living space. Whatever you start with, you end with finished square footage your family uses every week, and a number your Milton house carries at resale.

Milton requires a building permit before a basement is finished or converted into an additional residential unit, with staged inspections through construction. Additional units are permitted on most urban residential lots subject to the town's zoning, and suites must meet Building Code and Fire Code requirements for egress, fire separation and alarms. Our licensed structural engineer prepares and stamps the permit drawings, and we file the permit and manage every inspection to final sign-off.
