Secondary Suites & ADUs in Oakville.
Basement, garden and laneway suites are the fastest way to turn a Oakville property into an income property — designed, permitted and built by one accountable team.
Oakville is built for this move.
Oakville’s premium values mean a well-executed suite or conversion moves the needle more here than almost anywhere in the GTA.
For suites, that means one thing: the permission question is mostly settled. What decides your project is design, servicing and execution — and that’s exactly what we own.

As honest ballparks: a basement conversion typically runs $90k–$145k all-in at standard size and finish, and a new garden suite roughly $215k–$280k. Your free report prices your actual project for your Oakville lot.
Under Ontario’s Bill 23, up to three units are permitted as-of-right on most residential lots in Oakville, with Halton’s standards shaping design details. Individual designs still need permits and can be shaped by lot specifics — which is what the free report checks.
Typically 2–4 months for design and permits, then 4–8 months of construction depending on the suite type. We set a realistic timeline for your project up front — and one team carries it to keys.
