Granny Flats Brisbane
Mamet Homes builds granny flats and secondary dwellings across Brisbane and South East Queensland. Led by Adrien Mamet, we handle design, council approval, construction, and handover — on a fixed-price contract with a guaranteed build timeline. No variations. No surprises.
Imagine unlocking thousands of dollars in additional income while creating a beautiful, independent living space for family or tenants. Whether you’re looking to house aging parents close by, generate rental income, or add substantial value to your Brisbane property, a quality granny flat opens doors to financial freedom and multigenerational living solutions.
Too many Brisbane property owners hesitate because they’ve heard horror stories about building projects that blow budgets, drag on for months, or fail to meet council requirements. The reality is that most builders give rough estimates, charge endless variations, and leave you stressed about spiralling costs and uncertain timelines.
Every Mamet Homes granny flat is quoted on a fixed-price contract. Our detailed Bill of Quantities process means the price we give you on day one is the price you pay at handover. No variations, no cost surprises
We lock in supplier and subcontractor commitments before construction starts, so your build timeline is protected. Most granny flat projects are completed in 12–16 weeks from construction start.
Brisbane City Council and SEQ local councils have specific rules governing granny flat size, setbacks, height limits, and approval pathways. Mamet Homes manages the full approval process for every project — so you don’t have to.
Stay connected with daily updates, photos, and progress reports through your dedicated Mamet Homes app.
Our team has won multiple Master Builders and HIA awards for excellence. Every granny flat is built to the same standards with premium materials and superior workmanship.

A: Granny flat costs in Brisbane vary depending on size, design, site conditions, and council requirements. A Mamet Homes granny flat is delivered on a fixed-price contract — the price we quote is the price you pay, with no variations. We’ll give you an accurate cost indication after your free Discovery Call, once we understand your block and brief.
A: A Mamet Homes granny flat typically takes 18–26 weeks from initial consultation to key handover. Construction alone is generally 12–16 weeks. The timeline depends on design complexity and council approval pathway. We provide a guaranteed build timeline in every contract.
A: Yes — most granny flat projects in Brisbane require either a Development Approval (DA), Building Approval (BA), or both, depending on your block size, zone, and proposed design. Mamet Homes manages the full approval process as part of every build. You don’t need to navigate council yourself.
A: In most Brisbane council areas, granny flats (secondary dwellings) can be rented to non-family members. Rental income for a well-built granny flat in Brisbane typically ranges from $400–$600 per week, depending on size, location, and finish. We can advise on rental potential during your Discovery Call.
A: In Brisbane, secondary dwellings (granny flats) are generally capped at 80m² of gross floor area. Setback rules, block size minimums, and height limits also apply and vary by council area across SEQ. Mamet Homes assesses your specific block and council requirements before designing your granny flat.
A: Yes. Mamet Homes designs granny flats for all Brisbane site conditions — including sloped, elevated, and irregular blocks. Our designs are built primarily in an elevated format, which suits the majority of Brisbane’s hilly terrain and Queenslander-style blocks.
A: In Queensland, ‘secondary dwelling’ is the formal planning term used by councils. A granny flat is the common name for the same thing — a self-contained dwelling on the same lot as the primary home. Mamet Homes builds both under the full council approval process.
A: The first step is a free 20-minute Discovery Call with Adrien Mamet. We’ll discuss your block, your brief, and what’s realistically possible before any commitment. Book directly from this page — no obligation required.
A: Yes — we’ve built secondary dwellings used as music studios, home offices, hairdressing salons, and more. We can design and fit out the space for whatever purpose suits you, while still meeting council requirements.
A: No. Each local council has its own by-laws governing secondary dwellings — size limits, setbacks, and approval pathways differ across Brisbane City, Logan, Moreton Bay, Redland, and Gold Coast. Mamet Homes has experience across all SEQ councils.
A: Very. We select materials specifically for longevity and low upkeep — you’re not going to be repainting, resealing, or replacing things constantly. Easy to own is a design principle, not an afterthought.
A: Often yes. A secondary dwelling gives your kids independence on your block while you retain the asset. It can also generate rental income if their situation changes. We can walk you through the options on a Discovery Call.
A: Our designs are deliberately multi-functional. If your aging parent moves on, the dwelling can be rented out. If your situation changes again, it can be converted. The flexibility built into the design is part of what makes it a strong long-term asset.
A: For many Brisbane homeowners, yes — and here’s why. You build a granny flat on your existing property. You move into the granny flat, and rent out your main home. Under Australia’s 6-year absence rule, your main home can continue to be treated as your principal place of residence for CGT purposes for up to six years — meaning the capital gains tax changes to investment properties don’t apply in the same way. Meanwhile, a well-built, high-quality home in Brisbane commands strong rental returns — often enough to be positively geared without relying on negative gearing at all. That’s a meaningful shift from the old model of buying a cheap investment property and banking on losses. This is a strategy worth exploring with your accountant or financial adviser.
