Builders, civil contractors and councils across New South Wales are running longer jobs in more remote places. Renewable energy zones, regional housing and road upgrades all need site offices, crib rooms and amenity blocks that last the full project. This page explains where modular site offices fit in NSW, the approval steps, and what EcoPrestige supplies.
Why modular site offices fit NSW projects
Large NSW projects now set up proper site compounds. EnergyCo reported a workers’ camp and site office at Merotherie Road for the Central-West Orana Renewable Energy Zone. Compounds like these need offices, meeting rooms and amenities built for years of use, not a few weeks.
Regional housing adds to the demand. Build Australia reported the Key Worker Housing Program delivering 290 homes for teachers and police in more than 90 regional towns. Spread-out programmes need site facilities that can move from town to town. Our key worker housing NSW page covers that programme.
What EcoPrestige supplies
EcoPrestige supplies engineered structural steel volumetric modules, built and inspected in an offsite factory. Site compound modules include:
- Project and site management offices.
- Induction and meeting rooms.
- Crib rooms and drying rooms.
- Toilet, shower and change room blocks.
- First aid and storage rooms.
Modules join side by side or stack two high. Your builder or civil contractor handles pads, the crane lift, services and connections. Our ancillary buildings page for industrial sites covers similar buildings for permanent sites.
What does not fit
We do not run a hire fleet. Short jobs that need one cabin for a month are better served by hire. Modular supply fits long projects, multi-building compounds and offices that will stay as permanent buildings. Very remote sites need a confirmed truck route and crane set-down before we can commit to dates.
The approval path in NSW
EcoPrestige coordinates the module design with your consultants; permit drawings are issued by the registered or licensed practitioner the state requires.
Site offices and amenity blocks are typically Class 5 or 10a, confirmed by your building surveyor. These classes have no designer registration requirement in NSW. A registered certifier issues the certificates where approval is needed. Some temporary site buildings may fall under exempt or complying development, so confirm with your building surveyor or certifier early.
The Building (Approvals and Practitioners) Act 2026 received assent on 14 Aug 2026, according to MBA NSW. It brings the manufacture, supply, transport and installation of prefabricated buildings into the approvals system, with detail to come by regulation. Our NSW prefabricated buildings law page tracks it.
The programme
Pads, footings and service runs are built on site while the modules are built and inspected in the factory. Factory and site work run in parallel, so time on site is shorter. The compound can be in use soon after set and connection, which matters when the main works are waiting on it.
At the end of the project, a steel framed module can move to the next site or stay behind. Councils often keep compound buildings as depot offices or amenities, which turns a site cost into a permanent asset.
What to send us
- 1. Site location, access route and set-down area.
- 2. Peak headcount and the room mix you need.
- 3. Whether the compound moves between sites or stays.
- 4. Power, water and waste arrangements.
- 5. Date the compound must be in use.
FAQ: modular site offices in NSW
Do site offices need approval in NSW?
It depends on the site and how long the building stays. Some temporary buildings are exempt or complying development. Confirm with your building surveyor or certifier.
What NCC class is a site office or amenity block?
Typically Class 5 or 10a, confirmed by your building surveyor.
Does the new NSW prefab law apply now?
Most of the Building (Approvals and Practitioners) Act 2026 starts on dates set by proclamation. Until then the Design and Building Practitioners Act still applies.
Can EcoPrestige supply a whole compound?
Yes. We supply the modules; your builder or civil contractor sets them and connects services.
How is the price worked out?
The supply price is quoted for your site once we know the room mix, services and access.
