Sydney is in the middle of a granny flat boom and it is showing no signs of slowing down. Across the Hills District, Western Sydney, and the city’s outer suburbs, homeowners are converting their backyards into secondary dwellings at a pace not seen before. Easing interest rates, rising property values, and a series of NSW Government planning reforms that have made it significantly easier to approve and build secondary dwellings have all combined to create a surge in demand that is changing the residential construction landscape across the city.
For bricklayers in Sydney, this boom represents one of the strongest pipelines of residential work in years. And for homeowners planning a granny flat build, understanding why brick is the smartest material choice is one of the most valuable decisions they can make before construction begins.
The NSW Government has progressively relaxed planning rules around secondary dwellings over the past few years, reducing minimum lot size requirements and streamlining the approval pathway for complying development. For homeowners sitting on a block of land in suburbs like Rouse Hill, Penrith, Castle Hill, Blacktown, and Parramatta, the ability to add a rentable dwelling to their property without a lengthy council battle has made the decision far easier to act on.
Rental yields from granny flats across Sydney remain strong, and with the cost of living continuing to climb, multigenerational living arrangements are also becoming increasingly common. Grandparents moving onto the family property, adult children returning home, and homeowners looking to offset their mortgage with rental income are all driving enquiries for granny flat builds across Sydney right now.
When it comes to material selection for a granny flat, brick consistently outperforms the alternatives over the life of the dwelling. Lightweight construction methods using timber frames and fibre cement cladding are faster to build and cheaper upfront, but they come with ongoing maintenance costs, lower acoustic performance between the main dwelling and the secondary structure, and a significantly shorter lifespan before major remediation is required.
A brick granny flat, by contrast, delivers the same performance advantages that make brick the preferred material for larger residential and commercial builds. As we explored in our piece on why brick is still the best building material for commercial projects in Australia, the thermal mass of brick keeps internal temperatures stable year round, acoustic performance between spaces is far superior to lightweight alternatives, and a well built brick structure requires minimal maintenance for decades. For a granny flat that shares a property boundary with a main residence, those acoustic and thermal advantages are not abstract. They make daily life noticeably more comfortable for everyone on the block.
The cost of a brick granny flat in Sydney varies depending on the size of the structure, the complexity of the site, and the specification of brickwork required. Our guide on commercial bricklaying costs in Sydney in 2026 gives a useful breakdown of current labour and material rates that apply equally to residential and secondary dwelling projects. Getting an accurate, itemised quote from a licensed bricklayer before you commit to a design is always the smartest first step.
