Need a larger kitchen or living room? A bump-out addition is a cost-effective way to expand without major structural work. We handle foundation extensions, wall openings, and matched exterior finishes for a seamless look.
Save time and reduce disruption with a modular second-storey addition. Pre-fabricated components are custom-built and installed on-site, cutting build time in half. Fully engineered and approved to meet GTA zoning and building codes.
We convert basements and attics into warm, livable spaces with subflooring systems, moisture barriers, spray foam insulation, and proper ventilation. Maximize your home’s hidden square footage safely and legally.
Enjoy the outdoors year-round with a fully insulated sunroom or enclosed patio. We install low-E windows, structural framing, and weatherproofing for four-season comfort. Designed to blend naturally with your existing layout.

With Toronto’s housing prices rising, more families are choosing to renovate and expand rather than relocate. The various benefits of home additions in GTA include:
Skip the stress of real estate fees, moving costs, and bidding wars. A well-planned home addition gives you the space you need — bedrooms, offices, or a new suite — without leaving your neighbourhood.
Adding a second storey, an extra bathroom, or a rental suite can significantly boost your property’s value. Our custom home additions are designed with resale in mind and built to meet all GTA market expectations.
We create spaces that suit your lifestyle — open-concept kitchens, in-law suites, playrooms, and more. Every layout is thoughtfully designed and professionally engineered to integrate with your existing structure.
Home additions aren’t just bigger — they’re better. We use spray foam insulation, low-E windows, and energy-efficient materials that lower your utility bills while keeping your space comfortable year-round.
Whether it’s a kitchen makeover, exterior refresh, or complete home renovation, our team is here to bring your vision to life.
