Bringelly is home turf for us, and it is one of the most exciting places in Sydney to build right now. Granny flats in Bringelly and across Greater Penrith make great sense, with acreage and new estates side by side, and the Western Sydney Airport reshaping the whole district. Whether you want dual living for the family or a rental on a big block, this is a part of Sydney where a second dwelling really pays off.
At Hi-Tech Modular Homes we have built modular and transportable homes across NSW for more than 30 years, and our head office and display centre is right here at 1355 The Northern Road, Bringelly. Here is what local owners should know.
Bringelly sits at the heart of the Aerotropolis, the new precinct growing up around the Western Sydney Airport. The area is a blend of long-established rural acreage and fresh residential estates, and that combination is changing fast as infrastructure and jobs arrive.
For a granny flat, the acreage blocks are a dream. There is room to place a second home well away from the main house for genuine privacy, set it to catch the sun, and run a proper dual-living arrangement. The newer estate lots are tighter, so design and placement matter more, but the demand story is just as strong.
Dual living is one of the most popular reasons people in this area build. A separate, self-contained dwelling lets an adult child, ageing parents or extended family live close while keeping their own front door and their independence.
On a large block you can do this without anyone feeling on top of each other. If the second home is for older family, our notes on planning a granny flat for elderly parents are worth reading. A full two-bedroom design like the Snow Gum 60 with island bench kitchen and separate laundry suits family living, while the Banksia 60 with separate kitchen and deck is another comfortable choice.
The rules are set at the state level. Under the NSW Housing SEPP 2021 a secondary dwelling can be up to 60 square metres of internal floor area, with covered patios, verandahs and carports outside that 60sqm.
Most residential blocks of 450 square metres or more can be approved through the Complying Development Certificate (CDC) pathway, assessed by a private certifier in roughly 10 to 20 business days, which avoids a full council DA. Large rural or specially zoned acreage may sit outside the CDC criteria and need a DA instead. Our guide on how granny flat approval works in NSW covers both, and you can also explore house and land packages if you are building from scratch.
One of the perks of building locally is that you can walk through a finished home before you commit. Our display centre at 1355 The Northern Road, Bringelly lets you stand in the rooms, see the finishes and get a real feel for the size, which photos never quite capture.
Being based here also means delivery is as short as it gets. The home is built in our factory in about 8 weeks, then transported and installed on site in about 2 days, with our base just down the road. For acreage blocks, remember the two big regional cost multipliers: rock under the build, and how far services have to run if the connection point is some distance away.
Treat these as a guide and get a fixed quote once we have assessed your block. A complete granny flat in Sydney usually lands between about $120,000 and $300,000, with builds running roughly $2,200 to $3,300 per square metre depending on spec. On acreage, service distance is often the main thing that moves the number. Our cost guide for NSW in 2026 sets out every line item.

Usually yes. Large lots give plenty of room for dual living, though rural or specially zoned land may need a DA rather than the CDC pathway. We help you confirm which applies to your block.
Very fast, because our factory is right here. After the roughly 8-week factory build, install on site is about 2 days, subject to approvals being in place.
Being based in Bringelly, we are perfectly placed to help our neighbours across Greater Penrith and the airport district. Browse our granny flats and studios, then contact our team or drop into the display centre for a fixed quote and a proper look at what is possible on your block.
