Granny Flat Designs

We're the experts in design and construction, so you don't have to be.

Hills Granny Flats is a local business that has been serving the Castle Hill and surrounding areas for over 25 years. We provide accurate designs, communicate throughout the process and offer modern options for layout and design. Our experienced team is familiar with property and building regulations so you don't have to be!

Our aim is for you not to feel constrained on space, functionality or aesthetics. We want all of your needs met without compromising aspects of your ideal Granny Flat.

We also know what it's like looking at a blank canvas when it comes to adding an extra dwelling—you have so many ideas and questions about how it'll look or what exactly it'll do for you. That's why we make sure there are no surprises along the way by maintaining open communication throughout the entire process.

DO you provide a detailed contract outlining the scope of work, timeline, and payment terms?
