Why build a granny flat
One block, so many possibilities
A granny flat is one of the smartest ways to get more from your property — whether that's income, space for family, or future flexibility. Here's how Gold Coast homeowners are putting that extra dwelling to work.
Granny flat basics
Granny flats, explained
What is a granny flat?
A granny flat is a self-contained second dwelling built on the same lot as the main house. It has its own kitchen, bathroom and living space, so it can be lived in independently — making it ideal for family, rental income, a home office or downsizing without leaving your land.
Do I need council approval for a granny flat in Queensland?
Most granny flats need council approval, but the requirements vary by council and by your individual site. The good news is that KiaDom manages the approvals process for you as part of your build. You can also check your local council planning portals for area-specific rules.
How long does it take to build?
Build time varies with your design, site conditions and approvals. Rather than quote a one-size-fits-all figure, KiaDom gives you a clear timeline and a guaranteed handover date up front — so once your contract is signed, you know exactly when your new home will be ready.
Will it add value to my property?
A well-built granny flat adds usable living space and real flexibility to your property. That extra dwelling can house family, generate rental income or broaden your home's appeal at resale — letting one block work harder for you both now and into the future.

Reasons why
Real families, real reasons
There are many reasons you might build a granny flat. Here are just a few — told by the Gold Coast families who chose to build with us.
Reason 1
Downsize your home, upsize your lifestyle
Spending time with their little grandchildren was a major driver behind Shirley and Jim's decision to build a second dwelling in their own back yard. While their adult children raise their family in the main house, they'll always be close by so they don't miss a minute. Shirley and Jim also love that they can head off in their caravan whenever they like, knowing their pets and yard are being looked after.
Reason 2
A head start for a young family
With housing affordability becoming harder for young couples, Amanda and John wanted to help Emma and her partner Tristian. Together they built a beautiful addition to the home where everyone has their own privacy, and a young couple could begin their family and financial journey. The two-storey design has heaps of room for a full-size kitchen and bathroom, plus comfortable bedrooms and living areas.
Reason 3
Keeping loved ones close by
When Julie's mother Sandra found it increasingly hard to maintain the family home after her husband Phil passed away, Julie and Frank didn't want to consider aged-care facilities. Instead they built a custom-designed home on their own property, in keeping with the character of the estate. Julie worries less about Sandra's independence, Frank isn't maintaining two properties, and Sandra's health has improved — she treasures the time with her family, especially her granddaughter Ruby.
Reason 4
Dream mancave
Dennis wanted a personal retreat — an escape reminiscent of a turn-of-the-century alpine cabin. This award-winning mancave was constructed from reclaimed railway sleepers and salvaged roofing iron. It's the perfect space to take some time out and recharge the batteries.
Reason 5
Home office
The world is changing and there's a growing number of reasons to work from home. Reducing commuting time means more time with family, and not driving to work means a smaller carbon footprint. A well-designed home office, tailor-built to your needs, can be a comfortable and cost-effective way to work from home and run your business.
