The price to build a double garage varies widely based on size, materials, foundation needs, and local labor rates. For U.S. readers, the article quotes in USD and focuses on cost drivers that commonly influence a project of this scope, with per-unit and total estimates where relevant. The key driver is structure size, followed by foundation and roof type, doors, and finishing.
Assumptions: Midwest-style labor rates, standard concrete slab, basic pre-fab framing options, and typical access for a residential lot.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Double garage size | $18,000 | $28,000 | $40,000 | Typically 20×20 ft to 24×24 ft |
| Concrete slab | $4,000 | $7,000 | $12,000 | Include formwork and reinforcement |
| Framing and shell | $8,000 | $12,000 | $20,000 | Wood or steel frame; weather-tight shell |
| Roofing | $2,000 | $5,000 | $10,000 | Metal or asphalt, insulation options vary |
| Doors (2 panels) | $1,500 | $3,500 | $7,000 | Insulated overhead doors |
| Electrical wiring | $1,200 | $2,500 | $4,500 | Lighting, outlets, basic panel |
| Finishes and paint | $1,000 | $3,000 | $6,000 | Interior walls and trim |
| Permits and inspections | $400 | $1,500 | $3,000 | Local permit fees vary by region |
| Delivery/site prep | $600 | $2,000 | $4,000 | Site access and debris removal |
Assumptions: Project uses standard materials, no major site complications, and typical urban/suburban labor costs.
What Buyers Usually Pay For A Double Garage In South Africa
A typical project cost for a full double garage includes the shell, slab, roof, doors, and basic finishes. The total often lands in the $28,000–$40,000 range, with $18,000–$28,000 representing the shell and structure alone. Total price depends heavily on foundation type, chosen materials, and door systems.
Assuming a 20×20 ft to 24×24 ft footprint, a concrete slab and weather-tight shell are essential first steps. Per-square-foot estimates often translate to roughly $25–$70 per sq ft for the shell, with higher figures for steel framing or premium doors.
Breakdown Of Cost Components In A Double Garage Quote
Quotes break the project into major parts such as Materials, Labor, Permits, and Delivery. A typical breakdown would place Materials at about 40–50% of the total, Labor at 30–40%, and Permits plus Delivery at 10–20%. Concrete slab and framing dominate early budgets, while doors and electrical add finishing costs.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $12,000 | $18,000 | $28,000 | Wood or steel framing, sheathing, roofing |
| Labor | $8,000 | $12,000 | $20,000 | Frame, slab, rough-ins |
| Permits | $400 | $1,500 | $3,000 | Local building department |
| Delivery/Disposal | $600 | $2,000 | $4,000 | Material shipments and site cleanup |
| Doors and hardware | $1,500 | $3,500 | $7,000 | Insulated overhead doors |
| Electrical & lighting | $1,200 | $2,500 | $4,500 | Outlets, lighting, switches |
Key Variables That Change The Final Quote
Size and system type are the top price drivers. A 20×20 ft shell versus a 24×24 ft shell can swing costs by $5,000–$10,000. Material choice like timber frame versus steel, and roof type (metal vs shingles) also move the budget.
Other drivers include site access for deliveries, slope or drainage issues, and whether a full electrical panel upgrade is needed. A concrete slab with minimal reinforcement is cheaper than a heavy-duty slab for workshop use.
How To Trim The Price Without Compromising Safety
Scope control is the fastest way to save. Opt for a standard 20×20 ft footprint and a single-slope roof. Choose prefab or kit-form components where possible to reduce labor time and waste.
Seasonal demand and contractor availability can shift pricing by 5–15%. Scheduling in the off-peak season may lower rates. Consider staged work: shell first, then finish later if needed.
Regional Price Differences And Local Market Trends
Costs vary by region due to labor rates and permit fees. In higher-cost metro areas, expect the average to land toward the upper end of the ranges. Rural markets may offer savings but with longer lead times for materials.
Regional patterns also affect access to skilled trades and the availability of prefab components, which can influence both time and cost. A mid-range estimate in one locale could be 10–20% different in another.
Comparing Shell-Only Versus Fully Finished Garages
A shell-only build is significantly cheaper than a fully finished garage with drywall, insulation, and interior lighting. Finishing adds roughly 10–30% to the total project price depending on materials and QA requirements.
For budget planning, consider whether the space will be used as a workshop or a simple storage area, which drives finishing needs.
Labor Time, Crew Size, And Scheduling Impact On Price
Typical builds run 2–4 weeks for a shell, plus additional weeks for finishes. A two-person crew is common for shells, with an extra tradesperson for electrical and roofing when finishing. Labor hours and crew size directly influence the final quote.
Pricing Scenarios Based On Finish Level And Access
Scenario A: Basic shell with insulated panels and simple doors. Scenario B: Mid-range shell with drywall, paint, lighting, and upgraded doors. Scenario C: Premium finish with epoxy floors, climate control, and premium doors. Each scenario shifts cost by roughly $8,000–$20,000.
Scenario Details
- Scenario A: Shell only, basic doors, no insulation. Assumptions: standard access, no site complications.
- Scenario B: Finishes and mid-tier doors. Assumptions: standard electrical, lighting, and wall finishes.
- Scenario C: Full finish with premium doors and insulation. Assumptions: enhanced climate control and higher-end materials.
Three Real-World Quote Examples With Specs

Permits, Inspections, And Compliance Considerations
Permit costs vary by municipality and project size. Typical fees range from $400 to $3,000. Budget for potential inspections and code upgrades that may be required during the build.
SA-specific note: In areas with strict zoning or set-back rules, plan for longer approval times and possible design adjustments that impact price.
