01 — About
A new Perth name, with decades behind it.
West Coast Granny Flats is the work of three builders who've spent their careers constructing Perth homes. We've joined forces around one focus — turnkey granny flats, built the way a home should be built.
Between us we've seen what works on a Perth block and what doesn't: the soils, the setbacks, the trades worth keeping on speed-dial, the shortcuts that come back to bite. That experience is what you're hiring when you hire us.
Every project starts the same way: a conversation about your block, your budget, and the people who'll actually live in the finished space. From there, we design, manage approvals, and construct — without subcontracting the relationship out.
"We'd rather build fewer granny flats and stand behind each one, than push volume and chase deposits."

02 — What We Do
One offering, done end-to-end.
i.
Site Assessment
We start at your block. Setbacks, services, slope, access — we'll tell you honestly what's possible and where the trade-offs sit before you commit to anything.
ii.
Design & Drafting
A floor plan tailored to your site, lifestyle, and end use — whether that's family, rental income, or downsizing. Plans drawn properly for submission, not generic catalogues.
iii.
Council Approvals
We handle the full approvals process — building permits, planning where required, demolition if needed. You don't chase the local government; we do.
iv.
Construction & Handover
Slab to keys. Trades we know, materials we trust, a single point of contact throughout. Final inspection, walkthrough, and a finished home — not a punch list of "we'll get to it."
