Transportable granny flats, built for family.
Portable, transportable granny flats built in Motueka and delivered across New Zealand, including the South Island. New rules make building up to 70m² simpler, and we help with the council paperwork.
Granny flat rules in NZ just got simpler.
From 15 January 2026, a small stand-alone dwelling (a granny flat) of up to 70m² can be built in New Zealand without a building consent. It still has to meet the Building Code and be built by licensed professionals, and you still need a Project Information Memorandum (PIM) from your council before work starts.
A granny flat is a small, self-contained home on the same property as your main house. Ours are built in a workshop, then delivered and, in almost all cases, fixed to foundations on your property. The exemption does not cover a cabin kept on a trailer or other moveable base, tiny homes on wheels, container homes, or imported kitsets not built to the NZ Building Code.
General information only, not legal advice. Councils apply the rules differently and the guidance is updated from time to time, so check what applies to your property, or read the official granny flat guidance.

View all FAQsA transportable (or portable) granny flat is a small, self-contained home built in a workshop and delivered to your property, then, in almost all cases, fixed to foundations and connected to services. It does the same job as a site-built granny flat, with the building done off your section. It is not a tiny home on wheels.
Not if it meets the conditions. Since 15 January 2026, a new, stand-alone, single-storey dwelling of up to 70m² can be built without a building consent. It must be no more than 4m high, with the floor no more than 1m above the ground and at least 2m from boundaries and other buildings. It also has to meet the Building Code, with the work done or supervised by licensed building professionals. Tiny homes on wheels, container homes and imported kitsets not built to the NZ Building Code are excluded. Councils apply the rules slightly differently, so check yours.
Yes. You apply to your council for a Project Information Memorandum (PIM) before any building work starts. A PIM does not confirm that your granny flat meets the exemption, so it is important to check the conditions first. We can help you through it.
Possibly. Not needing a building consent does not automatically mean you do not need a resource consent. It can still be required if the granny flat breaks height, boundary or site coverage rules, or sits in a flood, coastal or other hazard area. Covenants on your title can also stop a second dwelling. Your council planner can tell you what applies to your section.
Yes. Councils can charge development contributions for a new dwelling, and your rates may go up. Delivery, foundations and service connections are also extra to the cabin price, and they depend on your site.
You can, but if you do, the Residential Tenancies Act and the Healthy Homes Standards apply, as they would for any rental. Talk to your council about any other rules for your area.
Every model above shows a live “from” price for the cabin. Use the instant price calculator to build an estimate for your cabin and your location, including delivery.
Not quite. A granny flat is a self-contained home. A sleepout is a smaller extra room for sleeping, usually without a kitchen or full facilities. Different consent rules apply to each, so check with your council which one fits your plans.
Yes. We build in Motueka and deliver across the South Island, including Canterbury and Christchurch, as well as the North Island. Tell us where your section is and we will give you a delivery estimate.
We deliver to most locations across New Zealand with insured transport, and manage site access planning, placement and setup. Tell us where your section is and we will give you an estimate.
From deposit to delivery, most projects run several weeks — the build itself happens in our Motueka factory while your site is prepared in parallel.
