Steel Frame Garage Kitsets NZ
SFML makes steel frame garage kitsets in New Zealand and delivers them free to your nearest Booths Logistics depot. Each kitset is the steel frame only: wall frames, roof framing and fixings, packed in bundles with assembly instructions. You add the cladding, roofing, doors and linings. Choose a DIY kitset you assemble yourself, or a pre-assembled frame, which is standard for the South Island and available for the North Island on request. Sizes run from 4.8 m x 5.8 m to 6 m x 18 m. If none fits your section, ask about a custom design. Call 0800 1 STEEL (0800 178 335), message us on WhatsApp or use the contact form for a quote.

Garage kitset questions
What is included in a garage kitset?
The steel frame and its fixings, including wall frames and roof framing. Cladding, roofing, doors, windows, linings and the concrete slab are not included. The listing for each size states exactly what comes in the box. See technical details and why choose steel.
Do I need a building consent for a steel frame garage?
It depends on the size, the use and your council. A single-storey detached building up to 30 m² can be exempt from building consent. For a kitset, the manufacturer or supplier must have had the design prepared or reviewed by a Chartered Professional Engineer. Plumbing work still needs consent. Most of our garage kitsets are larger than 30 m² and will need consent, so check with your council before you order. Source: building.govt.nz.
Should I choose a DIY kitset or a pre-assembled frame?
A DIY kitset arrives packed in bundles for you to assemble with instructions. A pre-assembled frame arrives already built. Pre-assembled is standard in the South Island, where we drive and drop it; the cost depends on distance and kitset size. North Island pre-assembled frames are possible but cost more, so we quote them as an estimate. See our process.
How does delivery work?
Delivery to your nearest Booths Logistics depot is free anywhere in New Zealand. You then arrange Booths to deliver to your site or collect it yourself. Dispatch takes about 14 days after you pay the deposit and approve the plans.
Can I get a size that is not on this page?
Yes. Call 0800 1 STEEL (0800 178 335), message us on WhatsApp or use the contact form and we will quote a custom design.
