Cottage kitset questions
Does a cottage need building consent?
A cottage with a kitchen or bathroom is not covered by the 30 m² small building exemption, which excludes those facilities. Since 15 January 2026 a single-storey detached dwelling up to 70 m² can be exempt, but you must notify council before and after building, get a Project Information Memorandum first and use licensed practitioners. Resource consent and district plan rules can still apply. Sources: building.govt.nz and Waitaki District Council.
Can it be a granny flat?
Possibly. That is the 70 m² exemption above, which has conditions. Ask your council before you order.
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.
