Space for adult kids
Their own place while they save for one.

Why so many granny flat plans never get built
Build a second home the traditional way and you're looking at months of trades, weather delays and a quote that keeps growing. Go cheap and you risk a unit that isn't built or wired to Australian standards.
So most people put it off. They're not sure about council, not sure what it will really cost, and not keen to find out the hard way.
Making room for family shouldn't feel like a gamble.
Why Master Modular
A real house, built to last, with nothing hidden
The same three questions come up in our showrooms again and again. Is it a real house? What will it cost all up? Will it last? So we built the answers into every home.
Each one is a permanent Class 1a dwelling under the National Construction Code, built on an engineered steel frame. It's backed by a 10-year structural warranty, a 25-year foundation warranty and 7-year builders indemnity insurance. And every quote lists what isn't included, in writing, before you sign.
Class 1a permanent home
Built to the National Construction Code, not a temporary cabin.
Engineered steel frame
Won't rot, warp or feed termites.
7-star energy rating
Double glazing and full insulation keep it comfortable all year.
BAL-29 bushfire rated
Built for bushfire-prone blocks as standard.
Fisher & Paykel kitchen
Induction cooktop, combi steam oven and integrated rangehood.
10 / 25 / 7 cover
Structural warranty, foundation warranty and builders indemnity insurance.
Only with modular
Start with one bedroom.
Add the next when you need it.
Every Master Modular home is built on the same matched module system, with the structure, services and roofline engineered for extra modules from day one. Buy the space you need today. When life changes, we add a bedroom beside it. It's a scheduled install, not a renovation.
- Engineered for it from day one
- Installed in days, not months
- Only pay for the space you need now

Can I build?
Will it fit? Will council say yes?
Can I fund it?
Most granny flat plans stall on one of those three questions. We can help you answer all three.
Your block
Send us your address and our team will check your zoning, setbacks, easements, slope and access, then tell you which designs fit. It's free, and you'll have your summary within [2] business days.
Council
In WA, a granny flat up to 70 m² that meets the R-Codes can skip development approval. In Victoria, most small second homes up to 60 m² don't need a planning permit. Either way you'll need a building permit, and we can handle the paperwork for you.
Your block
We work with construction-loan specialists who know modular builds, with indicative deposits from 5%.
Figures are indicative only and not an offer of credit. Lending is subject to approval.
What changes when you do

Put it off and nothing changes. The spare room stays a storeroom, Mum stays an hour's drive away, and the plan stays a plan.
With
Picture Sunday lunch where nobody has to drive home. Your parent has their own front door, twenty metres from yours. Or a tenant is helping pay the mortgage. And when life changes again, you add a room instead of moving house.
