2-Bay Cantilever Carport vs Double Brick Garage: Cost Breakdown Guide
Guide Type: Comparison guide
Compare a two-bay cantilever carport with a double brick garage: structure, foundations, roof drainage, electrical and finishing allowances for South African homes.
Quick answer
A cantilever carport is a focused external structure; a brick garage is an enclosed building element with walls, doors, slab, ventilation, drainage and finishing decisions. They should never be compared only by covered floor area.
How to compare the options
| Option | Best suited to | Include in the allowance |
|---|---|---|
| 2-bay cantilever carport | Covered parking where an open structure suits the site and security plan. | Engineering, posts or cantilever structure, footings, roof drainage, lighting and paving. |
| Double brick garage | Enclosed parking, storage or workshop use integrated with the dwelling. | Foundations, slab, walls, roof, garage door, windows, electrics, finishes and approvals. |
Cost and planning checklist
- Measure the actual bay dimensions and manoeuvring space; two vehicles need more than a nominal rectangle.
- Clarify whether paving, rainwater handling, power points, security and remote door motors are in the allowance.
- Check site coverage, boundary, municipal and structural requirements before fixing the layout.

Frequently asked questions
Can a carport become a garage later?
Sometimes, but the original structure, foundations, drainage, boundary position and approvals need to allow for it. Treat it as a design decision rather than a simple future add-on.
Why does a garage cost more per square metre?
Small enclosed structures carry concentrated fixed items such as a door, foundations, walls, roof edge details and electrical work.
Important
Confirm the final product, scope, installation method, drawings, approvals and professional requirements for the specific site before committing to work.
