A workshop garage in Calgary needs the right layout, electrical and heating to work as a real shop — dedicated circuits, good lighting, and insulation for year-round use. Here's how to plan one.
The Workshop Garage: Calgary’s Best Hobby Investment
For woodworkers, mechanics, metalworkers, and serious hobbyists, a properly built workshop garage is a life-changer. Here’s how we design and build them in Calgary.
Workshop Space Requirements
| Workshop Type | Min Space Needed | Ceiling Height |
|---|---|---|
| Basic woodworking | 400 sq ft | 9′ |
| Full woodworking shop | 600–900 sq ft | 9–10′ |
| Auto mechanic/restoration | 600–800 sq ft | 10–12′ (for lifts) |
| Metalworking/fab | 500–800 sq ft | 10’+ |
| General hobbyist | 300–500 sq ft | 9′ |

Electrical: The Foundation of a Good Workshop
A workshop garage needs dedicated heavy electrical from the start.
- Minimum subpanel: 100A (200A preferred for full shops)
- Circuits needed: 20A for general tools, 30A for table saw/planer, 50A for welding, 30A for air compressor
- 240V receptacles: At least 2–4 for large tools
- Outlets: Every 6 feet at workbench height and floor level
- Cost: $3,000–$8,000 for full workshop electrical including subpanel
Lighting
- Target: 50 foot-candles at workbench height minimum
- LED shop lights (4000K–5000K) flush-mounted or hanging
- 8-foot LED vapor-tight fixtures: $50–$150 each, very effective
- Task lighting at specific workstations
- Aim for no shadows in the primary work area
Air Compressor & Compressed Air Lines
For a serious workshop, run rigid copper or black iron compressed air lines along the walls with drops every 8-10 feet. Install while walls are open. Adding later means cutting into finished walls.
- 3/4″ main line, 1/2″ drops
- Include moisture trap and oil separator
- Cost to rough-in: $800–$2,500
Dust Collection
Plan your dust collection trunk lines during framing. A central dust collector with 4″ PVC branches to major woodworking equipment. Install before drywall.
Ventilation
Workshops generate fumes (finishes, welding, exhaust), dust, and humidity. Dedicated exhaust fan (300–600 CFM) and make-up air are important. Gas-fired workshop heating should be separated from finishing areas (explosion hazard with lacquer/stain).
Flooring
- Sealed concrete: cheap, functional, handles shop chemicals
- Epoxy: cleaner, easier to sweep, protects slab — $6–$12/sq ft
- Anti-fatigue rubber matting at primary workstations
