How it works
Most of the work happens before we arrive, so the time in your backyard is short.
Free site visit
Week 1
We measure your block and check setbacks, crane and truck access, services and drainage, and talk through which design suits you.
Fixed-price quote and contract
Week 1 to 3
You get a fixed price in writing, with inclusions, payment stages and a timeline. We sign a WA home building contract and arrange home indemnity insurance where the law requires it.
Drawings and building permit
Usually a few weeks
We finalise the drawings and engineering and lodge the building permit, plus development approval if your design needs it.
Factory build
About 4 to 6 weeks, then shipping
Your granny flat is made as a folding steel-frame module with windows, linings, kitchen and bathroom fitted.
Site preparation
While the flat is being made
We pour the slab or footings and run sewer, water and power to where the flat will sit.
Delivery and install
1 to 2 days
The module is craned onto the slab and unfolded, then fixed down. It is weathertight almost straight away.
Connections and finishing
Usually 1 to 3 weeks
Licensed WA plumbers and electricians connect and certify the services, and we finish the details, steps and paths.
Handover
Final week
Final inspection with you, keys, and the certificates you need for insurance or renting it out.
Timeframes are typical estimates. Your quote includes a timeline for your site, and approvals, shipping and weather can change it.
Why factory-made is faster
On a traditional build the slab, frame, roof, linings and fit-out all happen one after another in your yard. With a factory-made flat, the building is made at the same time as your site is prepared. That cuts the time trades spend at your house, and the disruption for you and your neighbours.
Common questions
How long does the whole job take?
It depends mostly on approvals and your site. Design, permit and manufacturing come first. Once the flat arrives, the install takes one to two days and connections and finishing usually take a few weeks. Your quote sets out the timeline for your job.
What if the crane can't reach my backyard?
We check access on the site visit. Most Perth blocks can be reached by crane over the house or down the side. If yours can't, we tell you straight away rather than after you have paid a deposit.
