20ft sleepout builds from ~$14,500 + container. High cube recommended.
Container sleepouts, built in Hawke's Bay
An extra bedroom without a building project. Our sleepouts start as 20ft or 40ft high cube containers and leave the yard insulated, timber- or poly-lined, wired with certified electrical, and finished with a ranch slider and proper windows — a warm, dry space that's ready the day it lands.
Teenagers, guests, boarders, home offices-slash-spare-rooms
Most sleepouts we build solve the same problem: the house is one room short. A 20ft sleepout gives you a genuine 13.8m² room; a 40ft version fits a bedroom plus ensuite or living nook. Because it's moveable, it can follow you to the next property — something a built extension can never do.
Built warm: insulation done properly
Hawke's Bay swings from frosty mornings to 30-degree February afternoons, so we insulate walls and ceiling before lining, fit double-glazed joinery options, and wire for a heat pump. The result holds temperature like a modern room, not a shed.
The consent question, answered honestly
Under NZ's building rules, a sleepout under 30m² without plumbing can often be built consent-exempt (Schedule 1), but district rules on placement, boundaries and flood zones still apply. We've delivered sleepouts across Napier, Hastings and CHB and can tell you what's typically been fine — final say sits with your council.
Sleepouts — common questions
How much does a container sleepout cost in NZ? +
Our sleepout fit-out starts around $14,500 on top of the container (new-build 20ft from $4,850+GST). A complete 20ft sleepout typically lands around $20,000+GST; 40ft high cube builds with ensuite more. Use the online configurator for a live estimate on your exact spec.
Do container sleepouts need building consent? +
Often not — single-storey detached buildings under 30m² without plumbing can qualify for consent exemption under Schedule 1 of the Building Act, and a 20ft container is well under that. Placement rules (boundary setbacks, flood zones) still apply, so confirm with your district council.
Are container sleepouts warm enough in winter? +
Ours are. We insulate before lining, and with a small heat pump or panel heater they hold comfortable temperatures year-round. Bare, unlined containers are not sleepable — insulation is the non-negotiable part of the build.
How long does a sleepout build take? +
Typically 3–6 weeks from deposit depending on spec and the engineer's queue, then it's delivered finished in a single truck movement.
