Frequently Asked Questions

But tiny homes can fit in very tiny spaces! We build small studios through to sizeable 3-bedroom homes to suit any parcel of land.

The minimum space required for a secondary dwelling is 30m2. We can visit your property to measure your land and work out the best-fitting granny flat, all free of charge with no obligation to go ahead.

Actually, granny flats are a frugal option because you don’t need to pay for the biggest expense: land! You’ll also save on stamp duty, rates etc. And, you could earn significant rental income every week!

We offer some of the best prices in South East Queensland but we never skimp on quality. We don’t believe in hidden costs and fees; the price you get from us includes everything, and we can incorporate extras that others don’t such as landscaping, decks and driveways.


Like any home build, the final price depends on size and inclusions. To give you an idea though, you could be looking at around $90,000 to $125,000.


However, when you compare that to the cost of a new home these days –approximately $300,000 – plus the savings on buying land and all the purchasing fees, settlement fees and so on, it’s a very small sum for the returns!

Well, it starts with one easy call! You’ll have a team leader who will help you from start to finish with sizing, choosing a plan, managing the build, and taking care of the paperwork.


We’ll visit your property to do a free measure and quote, and from there you can choose your favourite granny flat design and the fittings and fixtures. Our design team can help you if you need it. You’ll be assigned a team leader who will manage your project, give you updates on the build and complete all the inspections – and hand the keys over when it’s ready.

Building a sustainable granny flat doesn’t have to break the bank. By choosing eco-friendly materials like steel frames, incorporating energy-efficient features such as solar panels and smart home integration, you can significantly reduce long-term costs while helping the environment. Learn more in our detailed guide on Choosing a Sustainable Granny Flat Without Breaking the Bank, which offers practical tips for cost-saving strategies and maximizing energy efficiency.

That’s true, but you can add a granny flat to an investment property to quickly boost your yield. It can also make it easier to be approved for a loan if you can guarantee a higher rental return.

Once you factor all the extra costs like ground preparation, permits, labour, landscaping, fittings, fixtures, finishings and landscaping, you might find you’re paying a lot more (and taking far longer) to DIY than to have professionals do it.

People think DIY is better because it’s cheaper, but DIY kits focus only on the building materials. You’ll also need to have it assembled, run power and plumbing, pay for and pass inspections, add landscaping, fencing and concreting – the list goes on and on.

All told, the final price between DIY and custom-built is very small; it’s just that you did all the work instead of letting professionals take care of it for you! A DIY kit won’t include any kind of builder’s warranty either.

We include everything your granny flat needs, including driveways and landscaping. There are no hidden costs; your tiny home will be move-in ready complete with builder’s warranty.
