How do you get a modular home built in regional Western Australia? EcoPrestige runs a Domestic Program in two steps: Step 1 checks feasibility on your site, and Step 2 covers design, permits and the build by the practitioners WA requires. The modules are built in an offsite factory while a builder prepares your site, so time on site is shorter.
This page is for owners of land in regional WA: farming families in the Wheatbelt, retirees moving to the South West or Great Southern, and owners in the Mid West and Goldfields who cannot get a local builder to commit to a start date. The hard part is getting enough trades to a country block, in the right order.
Why modular fits regional WA
A conventional home on a remote block needs a long chain of trades to travel out, often more than once each. Weather, distance and trade shortages stretch that chain. A modular home moves most of that work into the factory. The frame, floor, walls, roof, linings and wet areas are finished under cover and checked before they leave. On site, the work shrinks to footings, services, the lift, the connections and the final fix.
That suits blocks where a local builder can handle the slab or stumps and the connections but cannot staff a full build.
If you only need a second dwelling, the WA Government removed the need for development approval on granny flats (ancillary dwellings) up to 70 m2 that meet the R-Codes deemed-to-comply rules, from 10 April 2024. A building permit is still needed, and your local government will tell you whether the exemption applies to your lot.
What EcoPrestige supplies
We design and draft your home, then coordinate engineering, the energy rating and certification. As the manufacturer, EcoPrestige is responsible for every module: built and inspected in an offsite factory to Australian engineering and QA, then delivered to site.
- Engineered structural steel modules with floor, walls and roof complete.
- Kitchen, bathroom and laundry fitted in the factory where your plan places them.
- Services roughed in and labelled for connection on site.
- A bill of quantities for the site works: footings, drainage, power, water and the deck or steps.
- A supply price quoted for your site, once Step 1 confirms access and footings.
EcoPrestige is not your builder. The builder on site is either your own builder or a local builder who prices the site works from our bill of quantities. That keeps local trades on the job and keeps the site contract with someone you can call. The two steps are set out on our Domestic Program page, including what Step 1 covers.
What does not fit
Modular is the wrong answer on some blocks. We tell you that in Step 1, not after you have paid for drawings.
- Tight blocks where neither a truck nor a crane can reach the set-down point.
- Steep slopes that need tall stumps or heavy retaining before a module can sit level.
- Flood-affected land or bushfire prone areas where the required rating changes the cladding, glazing or floor height beyond what the module allows.
- Heritage areas where the local government wants a form or material the module cannot match.
- Farm tracks that cannot carry a loaded truck in the wet season.
The approval path in WA
Building design is not a registered category in WA, so we can design and draft your home. Structural engineering is done by a structural engineer, and building engineers must be registered from 1 July 2027. A registered building surveying contractor checks the design and signs the certificate of design compliance. Your local government then issues the building permit. A home is typically Class 1a, confirmed by your building surveyor.
Planning is separate. Some rural and special zones need development approval for a new home. Check the local planning scheme with your shire before you commit. Confirm every signatory with your building surveyor or certifier. Our guide to building permits for modular buildings explains inspections and occupancy.
The programme
Step 1 is feasibility: the block, access, services, the planning position and a first layout. Step 2 is design, engineering, the energy rating, the permit and the build. Once the permit is issued, factory work and site work run in parallel. The modules are built and checked while your builder sets the footings and brings in power and water. The modules then travel by truck, a crane sets them, and the builder makes the connections before the final inspection. Our installation and crane guide shows what the site needs on lift day.
What to send us
- 1. The lot address and a copy of the certificate of title.
- 2. Photos of the block, the access track and the set-down point.
- 3. Bedrooms, bathrooms and how you plan to use the home.
- 4. Services on site now: power, water, septic or sewer.
- 5. Any letters from your local government about planning or bushfire.
- 6. Your builder’s name, if you already have one.

Regional WA modular homes: FAQ
Who builds my modular home on site in regional WA?
Your own builder or a local builder. They price the footings, services and connections from our bill of quantities and hold the site contract. EcoPrestige manufactures and delivers the modules.
Does a modular home need a building permit in WA?
Yes. A registered building surveying contractor signs the certificate of design compliance and your local government issues the building permit. Some rural zones also need development approval.
What happens in Step 1 of the Domestic Program?
We check your block, access, services and planning position and prepare a first layout. If modular does not fit your site, we tell you before you pay for full drawings.

Update, November 2026: WA’s draft R-Codes propose raising the granny flat limit from 70 m2 to 90 m2. The 70 m2 limit applies until the draft is finalised. See what the draft R-Codes propose.
