Studios, 1, 2 and 3 Bedroom
Free-Standing Designs

As the term indicates, Granny Flats were originally designed for the purpose of allowing an elderly family member to live with you... but still have some independence and privacy.

These days, they serve a whole host of other purposes. Teenage Retreat, Guesthouse, Extra Space, Workshop or Studio, Additional Income Source and perfect for the Home Office if you're working from home.

Regardless of the purpose of your Granny Flat, we seek to provide you with exceptional quality and service ensuring maximum return on your investment, following a pleasant and enjoyable building experience.

Simplicity, Style & Functionality

Simple by design... When working with a small space we need to ensure that we don't over-complicate things, so that we can avoid the feeling of a cluttered look and feel. 

Stylish by finishings... We believe that a Granny Flat is a reflection of your home. We want our customers to be proud of their Granny Flat; and this is ensured with your choice of finishes & fixtures, and our attention to detail.

Functional by nature... Definitely our most important principle. Your Granny Flat must suit its purpose (both now and in the future).

Remember that our designs are customisable... so if you don't see a design to suit your requirements, contact us now to discuss your options.

Minimal Bathroom

We engaged Wollongong Granny Flats to undertake Design, Planning, Approval & Construction of our 2 bedroom Granny Flat.


It was a pleasure to deal with a company that did what they said they would. I was informed throughout the design planning and construction stage of what was happening which allowed me to plan at my end. I found the Wollongong Granny Flats team to be honest and reliable. They did not charge unnecessary variations and actually completed additions works at no cost! I highly recommend Wollongong Granny Flats and have no hesitation in dealing with them again.

Grey Bed with Quilt

We are extremely happy with the team from Wollongong Granny Flats and how well they communicated throughout the build. The initial planning stage and throughout construction was an easy and hassle-free process and they always had time to answer any questions. We were kept up to date on each trade and knew exactly what was happening each day.

We highly recommend these guys and will definitely be engaging Wollongong Granny Flats for our next property!

Construction Manager Jack was keen to achieve a good result and all projects were successfully completed to both program and budget.
