The cost of renovating or developing a basement in Calgary depends on your needs, lifestyle, and vision. At AJ Construction Canada, our basement development packages start as low as $41,000 or $450/month* with financing for a standard build that includes a bedroom and a living room. While this option excludes a bathroom, we’re happy to accommodate if that suits your requirements.

We believe in quality without compromise. Every project, regardless of budget, is built using high-standard materials that stand the test of time. While some contractors may offer a lower upfront price, it’s often at the expense of lasting quality.

A typical basement with one bedroom, a bathroom, and a living room starts around $41,000. While this may seem higher than some competitors, we don’t cut corners. Our goal is to deliver exceptional value and a finished space you’ll love for years to come.

Not All Quotes Are Equal

When comparing basement development quotes, it’s important to ensure you’re evaluating the same scope of work and quality of materials. What may look like a lower price on paper often means missing details or downgraded products that will cost you more in the long run.

At AJ Construction Canada, we believe in transparent, all-inclusive pricing with no hidden costs or last-minute surprises. What we quote is what you pay—unless you decide to change something.
