How it works
Your basement development, step by step
The same four-step process as every Timeless Interiors project, applied to a basement specifically.
Free consultation
We assess your basement's ceiling height, existing windows, and layout, and talk through what you want the space to become — no charge, no obligation.
Fixed-price quote
You receive a fully itemized quote within 48 hours covering framing, permits, egress work if needed, and finishes — no surprise change orders later.
Permits, framing & rough-in
We pull the building permit, install egress windows where required, and complete framing, insulation, and plumbing/electrical rough-in before drywall goes up.
Finishing & final walkthrough
Drywall, flooring, and lighting come last, followed by a walkthrough together before we consider the project done.
Planning your project
What to consider before you develop your basement
A few practical things worth thinking about before your consultation.
Ceiling height affects what's possible
The City of Calgary sets minimum ceiling height requirements for finished basement space — this gets checked during your free consultation before anything is quoted.
Egress windows are non-negotiable for bedrooms
Any bedroom in a finished basement needs a code-compliant egress window for fire escape — if one doesn't already exist, cutting a new opening is a real line item in your quote, not an afterthought.
Secondary suites have their own requirements
If the goal is a legal secondary suite rather than just extra living space, that changes the permit, the inspection process, and the Secondary Suite Registry step at the end — worth deciding upfront.
