The scope involves building new space that connects to your existing home. This could be a second-storey addition over the current footprint, a rear extension expanding the main floor, or a combination that changes the home’s overall profile.

Structural work is always involved. Foundations may need reinforcement or new footings. Rooflines change. Mechanical systems—electrical, plumbing, HVAC—need to extend into the new space and often require upgrades to handle the increased load.

The complexity comes from connecting new construction to existing structure while maintaining the home’s integrity and ensuring everything meets current code requirements.

Additions require coordination between architects, engineers, and the city before construction begins. Permits for additions are typically more involved than interior renovations because you’re changing the building envelope and footprint.

We handle this coordination so you’re not navigating permit applications, zoning requirements, and engineering reviews on your own. Before construction starts, we map out the full scope, lock in critical decisions, and establish a realistic timeline based on your specific project.

During construction, one point of contact manages all trades. The goal is delivering your expanded home on schedule, with seamless integration between old and new space.

Home additions in Toronto typically range from $300,000 to $800,000 depending on the size of the addition, structural requirements, and level of finishes. A second-storey addition over an existing footprint differs significantly in cost from a rear extension requiring new foundation work.

Timeline runs 6 to 12 months from permit approval to completion, depending on the scope and city approval process.

We work with homeowners who value predictable timelines and clear communication over the lowest possible price. If that sounds like the right approach, we should talk.
