Three Doors, Endless Possibilities
A triple-car garage is the standard for Calgary estate homes and acreage properties. It’s not just about fitting three vehicles — it’s workshop space, toy storage (sleds, RVs, boats), and the foundation for a proper garage suite.
Standard Triple Garage Dimensions
| Config | Footprint | Fits |
|---|---|---|
| Standard triple | 30’x24′ (720 sq ft) | 3 vehicles |
| Oversized triple | 36’x28′ (1,008 sq ft) | 3 trucks + workshop |
| Tandem triple (2+1 deep) | 24’x36′ (864 sq ft) | 3 vehicles in a narrower lot |
| Shop-style triple | 40’x32′ (1,280 sq ft) | 3 vehicles + full workshop |

Attached vs Detached Triple
Attached: Direct home access, easier HVAC tie-in, counts toward home square footage. Preferred in cold climates like Calgary.
Detached: More design freedom, can go taller, easier to add a suite above, better for acreage lots. Costs slightly more per sq ft.
