Builders delivering school projects in New South Wales are under pressure to add classrooms fast without shutting down a working campus. Many schools still rely on portable classrooms that were meant to be temporary. Modular classrooms offer a permanent alternative that is built mostly offsite, then set during a short site window. This page is for builders holding school contracts in NSW.
Why modular classrooms fit NSW schools
A school site is busy every term. Noise, deliveries and site fencing all compete with students. Building most of the classroom in the factory cuts the time and the trades needed on campus, and lets the big lifts happen in school holidays.
The NSW Government is also moving its procurement towards modular. Its “From factory to front door” plan, released on 21 Jun 2026 with the 2026-27 Budget, sets government procurement to favour modern methods of construction. Builders who can offer a modular option are better placed as that policy flows through.
Modular classrooms are not portable classrooms
In industry use, a transportable building is finished offsite and moved to site on a truck in one or more pieces. It is permanent or relocatable depending on its footings and approvals. A portable classroom is usually a relocatable hire unit. A modular classroom on permanent footings is a permanent building, and it needs approval like any other building. Our modular vs portable vs transportable guide explains the difference.
What EcoPrestige supplies
EcoPrestige supplies engineered structural steel volumetric modules, built and inspected in an offsite factory, to the builder who holds the school contract. Typical modules are:
- General learning spaces, in pairs or rows.
- Staff rooms and offices.
- Student toilets and accessible amenities.
- Store rooms and small group rooms.
The builder handles footings, the crane lift, covered walkways, connections and landscaping. Our modular supplier for builders page explains how we work with head contractors.
What does not fit
We do not hold head contracts with schools or the department, and we do not hire relocatable units. A one-term classroom for a short spike in enrolments is better hired. Large halls and gyms with long clear spans are better site built. Tight campuses with no crane access need a plan before modules can be set.
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.
Classrooms are typically Class 9b, confirmed by your building surveyor. Class 9b has no designer registration requirement under the Design and Building Practitioners Act. A registered certifier certifies. School works may follow a government approval pathway, so confirm with your building surveyor or certifier which route applies.
The Building (Approvals and Practitioners) Act 2026 will bring prefabricated buildings into the approvals system once its parts commence, according to MBA NSW. Builders should watch for the prefabricated building declarations and instructions to be set by regulation.
The programme
Footings, services and walkways are built on site while the classrooms are built and inspected in the factory. Factory and site work run in parallel, so time on site is shorter. We plan the set dates with the builder around school holidays, so the lifts happen without students on campus.
What to send us
- 1. School location and the campus plan.
- 2. Number and type of rooms needed.
- 3. The holiday window you are working to.
- 4. Crane and truck access to the set-down area.
- 5. Your consultants and certifier, if engaged.

FAQ: modular classrooms in NSW
Are modular classrooms the same as portable classrooms?
No. A portable classroom is usually a relocatable hire unit. A modular classroom on permanent footings is a permanent building and needs approval like any other building.
What NCC class is a classroom?
Typically Class 9b, confirmed by your building surveyor.
Can classrooms be installed in the school holidays?
Yes. Factory and site work run in parallel, so the set and connection can be planned for a holiday window.
Does EcoPrestige contract with the school?
No. We supply modules to the builder who holds the school contract.
How is the price set?
The supply price is quoted for your site once we know the room mix and access.
