Where we build
Our office is in Vaughan, and we build across the Greater Toronto Area and elsewhere in Southern Ontario. Every municipality has its own zoning by-law, approvals and inspectors.

Who decides what, municipality by municipality
The zoning by-law, the conservation authority and the local rules a design has to meet in each place we build.

We take projects in these places as well.
What changes from one municipality to the next
The Ontario Building Code is the same everywhere in the province. Almost everything else that shapes a house is local.
- The zoning by-law: setbacks, height, lot coverage, driveway width
- The Committee of Adjustment that hears minor variances
- The conservation authority, where the lot is near a valley or a watercourse
- Heritage conservation districts and their design guidelines
- Tree protection and site alteration by-laws
- The hours construction is allowed
- Whether the lot is on municipal services or on a well and a septic system
The zoning review at the start of a project answers these for your lot.
Have a lot, a house or a set of drawings? That’s where we start.
Tell us where the property is and what you’d like to build, and we’ll tell you what we need to see next.
