A basement is the most underused floor of most Calgary homes, and the one with the most potential.
Done right, the lower level can become a family room, a guest suite, a home gym, a wine cellar, or all of the above. Done with care, it doesn’t feel like a basement at all.
At KoehnDesign, we approach basement renovations with the same design depth and craftsmanship we bring to the floors above. From layout planning through final styling, we shape lower-level spaces that genuinely earn their square footage.
Our Basement Renovation Process
Basements come with their own technical demands like moisture management, ceiling height, egress, lighting, and their own creative opportunities.
Our process is built to handle both.
01 Consultation & Discovery
We start with what you want the basement to be. Family room, secondary suite, home gym, wine cellar, guest space, or some combination? The answer shapes the layout, the finishes, and the systems that go in behind the walls.
02 Layout, Permits & Pre-Construction Planning
Basements require careful attention to egress, ventilation, ceiling height, and (for legal suites) City of Calgary secondary suite regulations. We handle all of it in pre-construction (drawings, permits, engineering, etc), so the build moves cleanly.
03 Material & Finish Selection
Basements live or die on lighting and materials. We select finishes that bring warmth and depth to a space without natural light, and design lighting in layers, not just overheads, so the room feels considered, not utilitarian.
04 Construction & Coordination
Our in-house team manages the build: framing, electrical, plumbing, HVAC, drywall, millwork, finishes. With every trade coordinated under one roof, the work stays on track and the design intent stays intact.
05 Quality & Completion
We walk through every finish, test every fixture, and address every detail before handover. The basement is complete when it would be hard to tell it apart from the rest of the home.
06 Styling & Final Layer
Furniture, art, textiles; the closing details that turn a renovated basement into a fully lived-in space.

Should You Renovate Your Basement?
A basement renovation is a different decision than a kitchen or a primary suite. You’re not replacing something tired; you’re creating something that hasn’t existed yet. The room you’re imagining is theoretical.
So the question isn’t should we update the basement; it’s what could the lower level become, and is it worth the build?
For most of our clients, the answer turns on how the family actually lives. If the upper floors are full but the basement sits half-finished or underused, you’re essentially carrying a floor of your home you don’t get to enjoy.
A well-renovated lower level in the form of a family room, a home gym, a guest suite, a wine cellar, a space for the kids that grows with them, can change the way the whole home functions.
Calgary winters make that especially true: from November through March, the basement is often the room a family actually lives in.
