WHAT WE DELIVER

Home Addition Design Services

Add space without leaving home. Adding on often costs less than moving — and you get to stay in the neighbourhood you love. Permit-ready drawings for: Rear, side, second-storey, family room, bedroom, garage, mudroom additions, sunrooms, and enclosed porches.

Home Additions

Home Additions That Blend Seamlessly Thoughtfully designed to extend your living space without sacrificing flow or character—whether you're adding a second storey, in‑law suite, sunroom, or rear expansion.

Second Storey Additions

Second Storey Additions Make the most of your existing footprint with a second-storey addition that avoids the cost and disruption of a full foundation. We design upward expansions that align with your home’s structure, from mastering bedroom suites to full-floor living areas, so your added space feels built-in—not bolted on.

Garage Additions

A garage addition that works as hard as you do — designed from the start around your specific use case, whether it’s a workshop, storage for toys and tools, a dedicated hobby space, or a clean, attached parking bay that ties into your home without looking like an afterthought.

Additions to your life

Framing that makes sense to a framer

We make sure our plans are laid out just the way a building crew would actually put them together—so there’s no head-scratching, just easy building.

Roof lines that shed water

A roof plane drawn at a desk can look great. Ours are designed so the water runs where it should, every time.

Connections that don't fight the existing house

Additions can feel like an afterthought. We detail the tie-ins so the new work reads like it was always there.

Windows placed for the view, not the grid

We put windows where they let in the morning light and frame the best sightline. Not just where a standard spacing puts them.
