Canberra builders, government agencies and civil contractors need site offices, crib rooms and amenities for jobs that often run for years: public housing, schools, health campuses and road works. Hire cabins suit a short fit-out. On a long programme, the hire bill keeps growing while the building never becomes yours. This page explains when buying modular site offices and amenities makes sense in the ACT.
Why modular site offices fit ACT projects
The ACT has a steady public pipeline. Region Canberra reported on 5 Jun 2026 that the 2026-27 ACT Budget funds 450 public homes. Programmes of that kind run across many suburbs and stages, and each stage needs a site team on hand with an office, a meeting room and amenities.
Canberra winters are cold, and many hire units are thin. A steel framed module with proper insulation and heating is a better place for a site team through June and July, and it can be reused for the next stage or kept as a permanent office or depot.
What EcoPrestige supplies
EcoPrestige supplies engineered structural steel volumetric modules, built and inspected in an offsite factory. Typical site and depot modules in the ACT are:
- Site offices and client meeting rooms.
- Induction and training rooms.
- Crib rooms and kitchenettes.
- Toilet, shower and change room blocks, including accessible rooms.
- First aid, plan and store rooms.
Modules can sit side by side or stack into a two-storey complex where the site is tight. Our site offices and temporary buildings hub sets out hire against purchase, and agencies planning a lasting building can read our modular office buildings page.
What does not fit
We do not hire buildings. For a short job, hire is the right answer. Inner-city sites with no crane set-down, or a site where the office has to fit under an existing structure, may need a different solution. EcoPrestige is not a builder: your team handles footings, the crane lift and connections.
The approval path in the ACT
EcoPrestige coordinates the module design with your consultants; permit drawings are issued by the registered or licensed practitioner the state requires. In the ACT, structural design is by a registered professional engineer under the Professional Engineers Act 2023, energy assessment is by a licensed building assessor, and a licensed building surveyor certifies. Building design is not licensed in the ACT. Confirm with your building surveyor or certifier.
Site offices and amenity blocks are typically Class 5 or 10a, confirmed by your building surveyor. If the office stays as a permanent building, the energy assessment and the footings need to suit permanent use from the start. For a site just over the border, the approval path depends on which side of the border the site is, and our Queanbeyan page covers that area.
The programme
Footings or pads and the service connections go in while the modules are built and inspected in the factory. Factory and site work run in parallel, so time on site is shorter. On a public housing or school job, that means the site team can be in a working office soon after the modules are set and connected.
What to send us
- 1. Site address and the set-down area for the office.
- 2. Peak staff numbers, including client and consultant visitors.
- 3. Room list and any accessible rooms needed.
- 4. Whether the building is for one stage, several stages or permanent use.
- 5. Services at the set-down point.
- 6. The date the office must be in use.
Builders working in both territories can compare our New South Wales site offices page, and Canberra projects more broadly are on our modular construction Canberra page.
FAQ: modular site offices in Canberra and the ACT
Do site offices need approval in the ACT?
Often, yes, particularly for long-stay or permanent buildings. A licensed building surveyor decides what applies to the site. Confirm with your building surveyor or certifier.
What NCC class is a site office in Canberra?
Typically Class 5 or 10a, confirmed by your building surveyor. Rooms used for training or meetings are checked as part of that.
Who signs off the structure?
A registered professional engineer under the Professional Engineers Act 2023 signs off the structure, and a licensed building surveyor certifies the building.
Can the same office serve a site in Queanbeyan?
Yes, but the approval path depends on which side of the border the site is. A New South Wales site goes through a registered certifier under New South Wales rules.
How is the price set?
We quote a supply price for your site after we see the room list, the stage plan and the crane set-down.
