Kit Set vs Site Built
Kit set garage: - Cheaper upfront ($28,000–$52,000 for double) - Faster to build (1–2 weeks once consent approved) - Limited design flexibility - Still requires consent, foundation, and electrical - NZ suppliers: Totalspan, Steel-Line, Ranbuild
Site built (custom): - Matches your house style and materials - Any size and layout - Higher cost ($42,000–$85,000+) - Takes longer (4–8 weeks construction) - Best for garages attached to or adjacent to the house
What Affects Garage Cost?
Size: Standard double garage (6×6m to 6×7m) vs oversized (7×8m+).
Cladding: Coloursteel/metal is cheapest. Weatherboard or brick veneer to match the house costs more.
Roofline: Simple mono-pitch is cheapest. Hip or gable to match the house costs more.
Floor: Plain concrete is standard. Epoxy coating adds $2,000–$5,000. Tiles add more.
Insulation and lining: An uninsulated, unlined garage is functional. An insulated, GIB-lined garage suitable for a workshop or conversion costs significantly more.
Services: Power (lights, power points, EV charger) adds $1,500–$4,000. Water adds more.
Consent Requirements in NZ
Garages generally require building consent. Exceptions:
- Exempt: A garage under 10m² may be exempt, but a standard double garage is well over this
- Most garages require consent — check with your local council
If attached to the house, it's part of the main building consent. Detached garages are a separate consent.
