Our Products
Since we're registered builders, we are not limited to the size or value of the shed we can build for you. This means you don’t have to find a registered builder to licence the shed you want, we do it all for you! And you can have peace of mind that you have a qualified builder not only designing your shed but also constructing it.

Yes. If you are handy and like a challenge, we can help you with your design, supply the kit, and you can take it from there.
If you feel out of your depth with shire applications, we can manage this for you. From shire approvals, through to the concrete slab and shed construction, you can have peace of mind knowing that you have a qualified builder not only designing your shed but constructing and managing your shed project from start to finish.
All our sheds are backed by the standard 20-year Bluescope steel warranty, and are custom engineered, comply with Australian standards, and are constructed using Australian made products. Our sheds are fully customisable and backed by Endurance Sheds and Structures, a Colorbond and Bluescope Steel specialist, Shedsafe Accredited, and manufactured right here in WA!
Before the construction of any new building, it’s best to check whether you will require a building permit first.
The following types of building work require a building permit:
- The construction, erection, assembly or placement of a building or an incidental structure.
- The renovation, alteration, extension, improvement or repair of a building or an incidental structure.
- The assembly, reassembly or securing of a relocated building or a relocated incidental structure.
- The changing of ground levels and site works associated with one of the above points.
The following types of building work do not require a building permit:
- Class 10a buildings (sheds or other non-habitable outbuildings) that are less than 10m2
and 2.4m in height. - Renovation, alteration, improvement, repair or maintenance of a building or incidental structure that does not affect the structural soundness of the building.
- Retaining walls that are smaller than 0.5m in height.
- Water storage tanks with a capacity of 5,000L or less.
When carrying out ‘builder work’ for another person, in most parts of Western Australia, registration as a building contractor is required.
A registered builder will have met the criteria and hold the relevant qualifications in order to obtain this registration. This registration is in the form of a number issued by and renewed with The Department of Mines, Industry Regulation and Safety.
What is ‘Builder Work’?
‘Builder Work’ is building work:
- For which a building permit is required;
- Is of a value of $20,000 or more and
- is carried out in the prescribed area of the state.
Alternatively, building works requiring a registered building contractor can be managed by you as an approved Owner Builder.
It’s important to not assume that your builder holds a current Registered Builders License. If you aren’t sure if your contractor holds a registered builders license, don’t hesitate to ask them.
