Home additions in Ontario

More space without moving. Galactic Renovation Inc. designs and builds rear additions, side extensions, and second storeys that look and feel like part of the original home.

Additions and extensions

Room to grow, built by one team

When your home no longer fits your life, an addition is often a better answer than a move. A new family room, a larger kitchen, a main-floor bedroom, or a full second storey can add the space you need while you stay in the neighbourhood you already like.

Because our tradespeople, project managers, and coordinators are all in-house, your addition is handled by one accountable team from the first sketch to the final walkthrough. There is no handoff between a designer, a permit runner, and a framing crew that has never seen your drawings.

How it works

A process you can plan around

Additions follow the same five-step process as every Galactic Renovation project: a free consultation and site visit, a design phase with a detailed estimate, permitting and planning handled by our team where the project requires it, construction by our in-house crew with regular updates from your project manager, and a final walkthrough backed by our warranty.

You get one point of contact and a clear schedule before work starts, so you always know what is happening on your property and what comes next.
