How much space do you need for a Granny Flat?

When deciding how much space you’ll need for a granny flat, this will largely depend on the size you’re looking to build and whether it’s a 1 bedroom or 2 bedroom granny flat. Ideally, we would recommend at least 20sqm for the Granny Flat itself and allowing for a minimum 1m space from any boundaries.

Can Fox Granny Flats organise demolition, pool removal and landscaping?

When looking to build one of our modular granny flats in Perth, you may require additional works to clear space and prepare the site. Works like this will typically be completed by external contractors that specialise in these areas. However, Fox can help arrange and assist with this.

What is the process of engaging with Fox Granny Flats?

The journey from initial enquiry to move in day is very simple and straightforward, which means the hardest part is choosing which of our designs you like best. Once you’re happy with the design you’ve chosen, we’ll send you a quote and arrange a site visit if needed. We’ll also liaise with your local council on your behalf and manage all the paperwork. After that, part of the joy of working with Fox Granny Flats is our quick build time. With our prefab granny flats going from factory to site in just 3 weeks, you’ll be moved in before you know it.

What are the benefits of building a Fox Granny Flat vs Traditional Brick and Tile?

The biggest benefit of a Fox Granny Flat is the ease and flexibility of installation and quick build times. Unlike traditional brick and tile, our prefab granny flats are built off site, so there are no tradies at your property until the site works are carried out. Because they are constructed in our factory before being transported to your home, they are unaffected by weather or other external factors which means you can move into your new granny flat in weeks, not months. Our modular granny flats can also be transported and installed practically anywhere, so if your circumstance changes you can relocate it with ease.

How much does a Fox Granny Flat cost?

Due to the customisable nature of our designs, our granny flats can vary in price, starting from $65k*. During the enquiry stage, we take the size, any inclusions or modifications to the design and location of transportation into consideration when producing your quote. If you would like any further information on pricing, please contact our office on (08) 6377 8335. Alternatively, please send an email to
