What We Build

Construction Services for Your Calgary Project

Basements, legal suites, garages, and commercial build-outs across Calgary and Airdrie. Every approved scope runs on a written fixed-price agreement. Permit coordination, required inspections, and a documented 5-year workmanship warranty are planned around the work the property actually needs.

Built for Calgary Homeowners

Lifestyle Basement Development
Scope-DependentFixed-PricePermit-Aware

Lifestyle Basement Development

That unfinished basement is space you already own. We design it first, then build the rooms your household actually needs: home theatre, gym, guest space, rec room, or a legal-suite path where the property supports it. Scope, permits, and finish level set the final number.

Legal Secondary Suites
Rental PlanningPermit-AwareSSIP Status Checked

Legal Secondary Suites

A legal suite can create a rental or family-use option, but rent depends on the address, unit, finishes, and live market. The catch most homeowners miss: "legal" means a separate entrance, egress, cooking and bathroom facilities, alarms, and the approved City permit path, not just a kitchenette. We check current SSIP intake before you budget around a rebate.

Garage Construction
Scope-DependentHeated OptionsPermit-Aware

Garage Construction

A Calgary garage lives or dies on its foundation and site plan. We assess the existing pad or plan the required foundation, then scope detached, oversized, insulated, and heated options around the property and current City requirements. Permit coordination and site preparation are included where the approved scope requires them.

Commercial Tenant Improvements
Scope-DependentUse-DependentMinimize Downtime

Commercial Tenant Improvements

For landlords and tenants: retail, office, and restaurant build-outs, from a few partition walls to a full interior gut. We identify the use, landlord, permit, inspection, and handover dependencies before setting a schedule. Recent build-outs include an African grocery in Forest Lawn and an auto retail floor in Foothills Industrial.

City incentive pathways: SSIP may support eligible in-home suite safety work up to the current City maximum, but new applications are currently waitlisted. The Backyard Suite Incentive has separate construction, infrastructure, accessibility, and bylaw-related amounts for qualifying detached suites. Funding is limited; confirm the current City intake and eligibility before budgeting around either program.
