Our team will streamline your development application for a new granny flat build
When you design your granny flat with us, we’ll design your granny flat and facilitate its prompt approval through a private certifier or Council.

Whilst not being builders or quantity surveyors, being in the industry for 25 years, we can provide local industry construction knowledge of the proposed construction cost and external consultant fees.

FAQs about our granny flat designs in NSW
How long does council approval take?
Each Council & LGA differs; we generally advise at least 6 - 8 weeks for a Development Application approval.
How can I make my granny flat more appealing to renters?
If you’re planning on renting out your granny flat for additional income, we recommend adding in the extra effort to make it cosy, stylish and functional to attract tenants. Think of additional bedrooms, a carport or enclosed garage, on-trend colour schemes and finishes, and lots of storage. These are all appealing elements tenants will be looking for while house-hunting.
Can you design multi-storey backyard cabins in NSW?
Absolutely. Our granny flat plans are completely customisable and are unique to each client and site to meet your individual needs, whether adding an additional storey to the structure or expanding the floor space to accommodate additional bedrooms and living spaces on a single-level flat.
How long does it take to build a granny flat?
There’s no one-size-fits-all answer to this question, as it depends on the size and design of the flat, the approvals process, and how many changes or amendments are required to the design. The Construction process and time depend on the carpenter or builder engaged.
Can I build a granny flat on a sloping block?
Yes! We can create a clever floor plan that utilises the land's natural slope, ensuring there is ample drainage and no risk of flooding when it rains. We will also take advantage of the slope to maintain the views from your block, no matter which way the block slopes.
Can I build a granny flat in a flood or bushfire-prone area?
Yes, but there will be some additional considerations for the design and build, e.g. materials and construction. There may also be additional requirements seeking council approval to build in these areas, including the requirement of a flood report and/or Bushfire or BPAD Report. We will arrange this for you if required.
I want to move my elderly family members into the flat. Can you accommodate this?
Yes, we have extensive experience designing granny flats for older adults and people with disabilities. Please let us know if you have specific needs and requirements, like wheelchair access. Our designers will ensure all of these elements are included in the design, so your family members can live comfortably and independently in your new granny flat.
