These are cabin plans from 15m² to 58m², with one or two bedrooms, framed in light gauge steel. They suit holiday sites, rural sections, backyards and short-term rentals, and owners who want a small, low-maintenance building that goes up quickly. SmartFraming supplies the steel frames only. Your builder supplies and installs everything else, including foundations, cladding, roofing, windows, doors and linings.
What's included
- Wall and roof framing, fully made up or as flat-packs when required
- Drafting changes to adjust opening sizes and positions
- Grommets for the service holes pre-punched through the framing
- Erection screws to stand the frames
- Detailed assembly plans
- Floor panel for small builds such as cabins and small sheds (on request)
- Engineering reports to support a council application, for sign-off by a third-party engineer (on request)
Not included: Cladding, roofing, windows and doors, linings, insulation, foundations and installation are supplied by your builder. Delivery is quoted separately, based on your location.

Sizes and uses
Most cabins in the range have one bedroom, and nine have two. Many are long and narrow, around 2.9 m to 3.6 m wide and up to 13.3 m long, which suits transport, narrow sites and a view along one side. Wider plans around 4 m to 5 m give a more open living area.
Roofs are mostly mono pitch at 3° to 8°, with some gable and hip options. For a small cabin we can also supply a steel floor panel on request, so the floor and walls come from the same set of drawings. Openings can be changed at the drafting stage.
Consent notes
Twenty-eight plans in this range are 30m² or under. A detached, single-storey building of up to 30m² can be built without a building consent if it meets one of the Schedule 1 exemption routes and every condition of that route. That exemption doesn't allow a toilet, shower or kitchen, though, and the cabin plans include a bathroom. A cabin with a bathroom or kitchen needs a building consent, or may qualify under the separate granny flat exemption if it's a self-contained home.
Our guide to the 30m² building consent exemption explains the routes and the conditions that catch people out. We can supply engineering reports for a consent application, for sign-off by a third-party engineer, and recommend cost-effective engineers.
