Home Additions

Home Additions in Ottawa

Add space, light and value to the home you already love. We design, permit and build additions that feel like they were always part of the original house.

A well-planned addition can give you the space you need without the cost and disruption of moving. Whether you're growing your family, adding rental income, or finally getting the kitchen and living area you want, Branton Construction Group can extend your home from foundation to finishes.

We handle zoning checks, architectural drawings, City of Ottawa permits, structural work, mechanical tie-ins, insulation, exterior matching and interior finishing — so the new space blends seamlessly with the old.

What we build

Second-storey additions

Add a bedroom, bathroom, or primary suite above the existing footprint without losing yard space.

Rear & side extensions

Expand your kitchen, living room or dining area outward with a foundation that matches the existing home.

Sunrooms & covered porches

Bright, usable space you can enjoy three seasons a year — properly insulated and tied into the structure.

In-law suites & secondary units

Self-contained living spaces with kitchens, bathrooms and private entrances, built to Ottawa bylaws.

Built to match what you have

Additions shouldn't look like additions. We match siding, brick, roofing, trim, flooring and millwork so the new space reads as one coherent home — not a tacked-on box.
