Not every shed is about machinery. A small, well-built steel shed can be an art studio, a home gym, a potting shed, a hobby workshop or simply somewhere to get away. The difference between a box and a room you love is in the details.
Use the 30 m² exemption wisely #
A single-storey detached building up to 30 m² can be built without building consent, if it meets every condition:
- at least 1 m from any boundary or house (since October 2025)
- no more than 3.5 m high above the floor, with the floor no more than 1 m off the ground
- no toilet, sink or drinking-water storage
- a kitset designed or checked by a chartered professional engineer, built or supervised by a licensed building practitioner, or a lightweight DIY build following the B1/AS1 solution
Under 10 m², there’s no boundary distance at all. The district plan still applies, so check your zone’s rules. See our consent post for the details.
Light makes the room #
Windows, a glazed door or roof skylights turn a dark box into a space you’ll use. Think about which way the windows face, and where the sun falls when you’ll be in there.
Comfort #
Insulation and lining make a small shed usable year-round and stop condensation dripping off the roof. Lined walls are also easier to hang shelves, art or gym gear on.
Power #
Lights, sockets and a heater make a hobby shed far more useful. Electrical work must be done by a licensed electrician. Running power from the house is easier to plan before the shed goes up.
Looks #
A she shed or studio usually sits close to the house and garden, so looks matter. Pre-painted steel colours can match the house, and roof shape, overhangs and trims all change the feel.
A note on sleeping #
The small-building exemption only allows sleeping in limited cases, and Steelspan doesn’t build sleepouts or sheds to live in. If you want a sleepout, talk to a builder who specialises in them.
Yes, we supply small sheds #
No two small sheds are the same in their needs or budget, so talk to us early and we’ll help you get it right. Even at this size, every Steelspan shed comes with an engineer’s certificate, PS1 and calculations and plans, the same as our bigger buildings, whether you build it yourself or we build it for you.
Windows and glazed doors #
We can supply aluminium joinery for small sheds, and these days it’s typically double glazed. Joinery doesn’t travel well over long distances, in price or because it’s fragile, so it’s best sourced as close to you as practical. We work with joinery suppliers around the country, so ask us about the options in your region.
