How much does custom home building cost in Mississauga?

With Zigma Group, custom home building starts from $330 per sq ft. Prices are in Canadian dollars before HST, as of October 2026, and are confirmed after a site visit. The main factors are size and complexity of the design; finish level inside and out; and site conditions, demolition and servicing.

Should I renovate or rebuild?

It depends on the condition of the existing structure, how much of the layout you want to change and what zoning allows on the lot. We assess both routes and explain the trade-offs.

What approvals does a new custom home need?

Zoning review, a demolition permit if an existing house is being removed, and a building permit. A minor variance is needed if the design exceeds a zoning limit.

Yes. We work throughout Mississauga, including Port Credit, Lorne Park, Mineola, Streetsville, Erin Mills and Clarkson. Call +1 (647) 718-3913 to arrange a visit.

Custom Home Building in Mississauga

When renovating is not enough, we build new. One team takes the project from the lot and the first drawings to the day you get the keys. In Mississauga, the housing ranges from lakeside homes on large treed lots in Lorne Park and Mineola to 1970s to 1990s subdivisions further north.

Before you start

What to know.

Feasibility
Before design, we look at what the lot and zoning allow, what has to be demolished, and how that fits your budget.
Approvals
A new house needs zoning compliance, a demolition permit where an old house is removed, and a building permit. Some designs also need a minor variance.
One team
Design decisions and construction costs affect each other at every step. Keeping them in one team stops drawings being produced that cannot be built for the budget.
