For generations, the Australian dream was simple: big backyard, plenty of space between neighbours and enough room for a game of cricket out the back. But Perth’s housing landscape is changing.
Blocks are getting smaller, land is becoming more expensive and harder to secure, and future homeowners are having to think differently about how they use every square metre. Yet, Perth families still want the same things they always have: spacious living areas, multiple bedrooms, home offices, outdoor entertaining space, plenty of storage and sometimes even the space for multigenerational living.
The Block Size Shift
While the quarter-acre dream once defined suburban living in Perth, today’s reality is quite different. New land releases are getting smaller and established suburbs are becoming increasingly sought after.
Block sizes across Perth have changed considerably over the past 20 years. In the early 2000s, the average new block was around 564m². Today, it sits closer to 375m², a reduction of approximately one-third. Meanwhile, smaller lots under 300m² have become increasingly common as developers respond to affordability pressures and changing lifestyle preferences.
This trend is expected to continue as Perth looks for ways to increase housing supply and make better use of existing urban land, with recent planning reforms encouraging more infill development and subdivision opportunities across the city.
Why Infill Is Becoming So Important
Perth’s future housing supply will require a mix of building outwards, building upwards and delivering more urban infill housing. This shift is creating opportunities in suburbs where large blocks are being transformed into smaller, more efficient homes.
Areas such as Balcatta, Nollamara, Innaloo, Mount Lawley, Yokine, Doubleview and Osborne Park are seeing increased interest from future homeowners who want proximity to employment, schools, and established infrastructure without moving further from the city. For many, subdividing or developing an infill block can unlock value while creating housing that matches the modern lifestyle.
The Catch: Families Need More Space, Not Less
Although block sizes are getting smaller, many households are actually needing more space than ever before.
Rising property prices and cost of living pressures have contributed to changing living arrangements, with adult children staying at home for longer and multigenerational living becoming increasingly common. At the same time, many families now require home offices, larger kitchens with sculleries, additional living areas and more storage space.
It’s a modern housing paradox: while the amount of land available is decreasing, the demands placed on the home are growing. The challenge isn’t simply fitting a house onto a smaller block. It’s creating a home that can comfortably accommodate the way modern families live.
The Rise of Smart Home Design
As blocks become smaller and households’ needs become more complex, every square metre needs to work harder. Rather than sacrificing valuable outdoor space or compromising on the features families want, future homeowners are turning to smarter floorplans.
The solution isn’t always a larger home. For some, it’s a cleverly designed single storey home that makes better use of the available land. For others, it’s a narrow lot or two storey design that creates additional living space while preserving room outdoors. The key is designing a home around the block, budget and lifestyle requirements of the people living in it.
As Perth continues to embrace smaller blocks and more infill development opportunities, smart design is becoming less of a luxury and more of a necessity. It is no longer about how much land you have, but more how effectively you use it.
