Luxury basement finishing for Barrie homes. Free 3D design, an itemized price that locks before you sign, a lifetime workmanship warranty and a written finish date that pays you $200 for every late day.
Get a Free EstimateSee our projectsBarrie's newer subdivisions, Holly, Ardagh, Painswick and Innis-Shore, come with tall, dry basements built for finishing, and as one of Ontario's fastest-growing commuter cities, demand for in-law and income suites keeps climbing.
The city requires second suites to be registered, with fire and property-standards inspections, and a properly registered Barrie suite rents fast. Whatever you start with, you end with finished square footage your family uses every week, and a number your Barrie house carries at resale.
Theatres, bars, gyms and family spaces. Wood studs with metal tracks and moisture-resistant drywall as standard, finished to match the rest of your home.

Underpinning for ceiling height, waterproofing, and permitted separate entrances for legal Barrie second suites.
EXPLORE STRUCTURAL WORK →Barrie requires a building permit for basement finishing, and second suites must be registered with the City of Barrie, a process that includes fire and property-standards inspections so every unit is safe and documented. Suites need proper egress, fire separation, interconnected alarms and compliant ceiling heights. We design to code from day one, pull the permits, pass the staged inspections, and walk the registration through with you so your suite is finished, registered and legal.

We have not published a Barrie project yet, so here is a recent one from Bradford, built to the same specification and warranty we bring to Barrie.
Two bedrooms, a bathroom with a custom tiled shower, and a laundry room with washer plumbing and a sink. A slat feature wall with integrated LED, soundproofing, seven solid-core doors, window casings, 62 pot lights and a heat-pipe relocation, on an insulated DRICORE R+ subfloor. Built in two sections, which added about a week and a half.
