Victorian builders, civil contractors and councils need site offices, crib rooms, toilets and change rooms that work for the life of a project, and sometimes for years after it. Hire fleets suit short jobs. Long projects, council depots and multi-stage estates often need something better built and owned outright. This page explains where modular site offices and amenities fit in Victoria, and what EcoPrestige supplies.
Why modular site offices fit Victorian projects
Victoria has a long pipeline of regional work. Build Australia reported more than 350 modular social homes planned by mid-2028 across Geelong, Ballarat, Bendigo, Ararat and Gippsland. Projects like these run for many months across several sites, and each needs a site office, meeting room, crib room and toilets.
When a project runs long, owning a well built office can make more sense than paying hire every month. A steel framed module can be moved to the next job, or kept as a permanent depot office. Our site offices and temporary buildings page explains the difference between hire and purchase.
What EcoPrestige supplies
EcoPrestige supplies engineered structural steel volumetric modules, built and inspected in an offsite factory. For site use, typical modules are:
- Site offices and project managers’ rooms.
- Meeting and induction rooms.
- Crib rooms with kitchenettes.
- Toilet, shower and change room blocks.
- First aid rooms and store rooms.
Modules can be joined side by side or stacked to make a larger complex. Your builder or site team handles footings, the crane lift, services and connections.
What does not fit
We are not a hire company. If you need a single cabin for a few weeks, a hire fleet is the right answer. Modular supply suits projects that run long, need several linked buildings, or want a permanent office at the end. Sites with no truck or crane access also need planning before modules can be set.
The approval path in Victoria
Site offices and amenity blocks are typically Class 5 or 10a, confirmed by your building surveyor. A building permit is needed from a registered building surveyor unless the surveyor confirms an exemption applies to a temporary site building. Structural design is by a PERA-registered structural engineer. Commercial building design is not a registered category in Victoria.
EcoPrestige coordinates the module design with your consultants; permit drawings are issued by the practitioner the project requires. Confirm with your building surveyor or certifier whether the building is temporary or permanent, because that changes the footings and the permit. Our transportable buildings Victoria page covers relocatable and permanent use.
The programme
Site preparation, pads or footings and service connections go ahead while the modules are built and inspected in the factory. Factory and site work run in parallel, so time on site is shorter. For a site office, that means the team can move in soon after the modules are set and connected, rather than waiting on a site-built shed.
What to send us
- 1. Site address and site access details.
- 2. Number of staff on site at peak, and the mix of office and amenity rooms.
- 3. Whether the building is for one project or will move between jobs.
- 4. Water, sewer and power available on site.
- 5. Date you need the office in use.
Councils planning depots or staff buildings should read our regional council procurement guide.
FAQ: modular site offices in Victoria
Do site offices need a building permit in Victoria?
Often yes. A registered building surveyor decides whether a permit or an exemption applies. Confirm with your building surveyor or certifier before the modules are ordered.
What NCC class is a site office?
Typically Class 5 or 10a, confirmed by your building surveyor.
Can the modules be moved to the next project?
Yes, if they are set on footings designed for relocation and the permits allow it. Steel framed modules are built to be lifted more than once.
Do you hire site offices?
No. EcoPrestige supplies modules to buy. For short jobs a hire fleet is usually the better fit.
How is the price set?
The supply price is quoted for your site once we know the rooms, the services and the access.
