Frequently Asked Questions
What if my land is too small?
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.
Granny flats seem expensive to me?
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!
I rent, so I can’t have a granny flat
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.
Can't I build one DIY for cheaper?
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.
Can I build a sustainable granny flat without exceeding my budget?
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.
