08 6285 3123You don’t commission a six-figure structure for generic results. You do it because you expect craftsmanship, clarity, and a team that understands how to turn a blank block into a functional, high-quality space. At Armour Homes, we design and construct granny flats in Perth that do exactly that fit your property, suit your family, and increase long-term value with purpose.
Unlike most builders who treat granny flats as a side hustle, this is our core business. We know every regulation. We’ve worked across suburbs, councils, and block types. And we deliver each project with the level of detail you’d expect from a full-scale custom build. No pushy templates. No shortcuts. Just smart design, solid construction, and honest pricing.
It starts on your site. Always. We visit your property, assess the block size, boundaries, and setback limitations, and begin a custom design consultation based on who the flat is for: family members, future tenants, or a standalone home office.
From there, we guide you through granny flat designs that complement your existing home architecturally, spatially, and structurally. Our team handles all council approvals, planning submissions, and construction logistics. You won’t be chasing forms or arguing with certifiers. We manage the process end-to-end so you can focus on the vision, not the paperwork.
We deliver in 12–16 weeks, weather depending, using local tradespeople who are trusted, not subcontracted out blindly. All our granny flats are fully constructed to meet Perth’s codes for ancillary dwellings, maintaining structural integrity and energy compliance from the slab to the roof.
A compact studio design that combines minimalist charm with practical, open-plan living. Ideal for a backyard retreat, guest accommodation or independent living without compromising on style.
A smart 1-bedroom, 1-bathroom layout designed for comfort and efficiency. With its open-plan flow and modern finish, this granny flat is perfect for singles, couples or downsizers looking for their own space.
Spacious and private, this 2-bedroom, 2-bathroom design is suited to families, multigenerational living or those wanting extra room to relax. Enjoy the benefits of a full-sized layout with a contemporary edge.
We don’t force you into cookie-cutter layouts. Every Armour granny flat is designed around your block, your budget, and your needs. Want a granny flat that complements your heritage home? We match colours, lines, and roof pitches. Need to squeeze a functional home into a sloped site? We work with elevation, not against it.
Need disability access for older family members? Done. Want storage for tools, bikes, or gym gear? We’ll show you integrated storage solutions that don’t eat up living space.
This is where most builders get it wrong; they start with a brochure. We start with your block.
