Our services

Open the door to a space you love

Build or renovate your seasonal home with our in-house team and network of specialists who stand behind their work

Design and Build

Create a space where you feel at home, whether it's for a weekend, a season, or for generations to come. We design and build seasonal homes, boathouses, and bunkies that make a statement while staying true to the natural landscape.

Custom Build

Bring your blueprints, and let us turn them into a space you never want to leave. Our skilled and knowledgeable team of trades professionals will take your pre-designed plan and make it a reality you can walk into.


Update your home or secondary buildings so you can enjoy where you hang your hat more. Add bedrooms, change an existing layout, expand your space, or finally build the Muskoka room you’ve always wanted.

If you need an emergency restoration service, we are affiliated with a leading national property restoration company. We can complete renovations in cooperation with the repair work done by our sister company.
