How a home addition project works

What to expect when you get started.

Your designer stays involved throughout the project and coordinates the work, including licensed trades when they are needed.

Consultation

Meet with a designer to talk through the space you need, how it connects to your home, your budget and timing.

Design

We plan an addition that blends with your home's style and prepare the layout and material plan.

Permits

Most additions need a permit. We help with the process and coordinate the drawings and documentation.

Proposal

You get a detailed quote covering materials, trades and build, locked in once you sign off.

Construction

Our team coordinates the build and licensed trades, keeping your project on track from design to done.

Final touches

We complete the addition, clean up and walk the finished space with you.

When you choose us, you’re choosing an efficient, reliable team that uses the right materials for your needs. We give you personalized service on your schedule, keep you posted on every change, and treat your word as final.

A new bedroom, a sunroom, or a full second storey: we help you plan an addition that fits your needs and your home's style.

Materials and trades handled
