Frequently Asked Questions
What if my land is too small for a granny flat?
You’d be surprised how often a granny flat can fit, even on smaller lots. We use professional siting software to map your block and check setbacks, access and services. In most cases, we can design a compliant layout that works within your available space and council rules.
Granny flats seem expensive, why do they cost that much?
A quality granny flat is a fully engineered, council-approved home built to the same standards as any new dwelling. Costs cover design, approvals, site works, connections and construction using certified materials. Our builds are fixed-price and include everything — no hidden extras or cut corners.
Where do I start if I’m thinking about building a granny flat?
Start by contacting our experienced sales team. We’ll map your block, discuss your needs and budget, and show which designs will fit. From there, we can provide an initial proposal and guide you through the Preliminary Assessment stage.
What’s included in your fixed-price granny flat builds?
Our builds include design, building approval, site works, and full construction. Each flat features a durable steel frame, hybrid flooring, 2550mm ceilings, 300mm eaves, and concrete piers up to 1200mm deep — all designed for Queensland conditions.
I rent my home — can I still have a granny flat?
Unfortunately, you’ll need to own the property to build a granny flat, as council approval must come from the landowner. However, if you’re planning to buy, we can help you assess potential properties to ensure they’re suitable for a future build.
Can’t I just build a DIY granny flat for cheaper?
DIY or flat-pack granny flats may look cheaper upfront, but they rarely meet building or council standards in Queensland. We provide fully certified, insurable granny flats that meet all local codes — protecting your investment and adding long-term value to your property.
Will I have to do a lot of work myself during the build?
Not at all. We manage everything — from design and approvals to construction and handover. You’ll have one point of contact throughout the process, so you can relax knowing your build is fully handled by experienced, licensed professionals.
