For generations, the quarter acre block has been at the heart of the Australian dream. In 1900, the average block was a whopping 1,200 square metres and the average house around 150 square metres.
Post-war, the quarter acre block (around 1000sqm) provided room for a family home of around 200 square metres and a substantial backyard, commonly filled with a chook house, shed, vegetable patch, fruit tree, a Hills Hoist and a decent patch of lawn to kick the footy or play cricket. The quarter acre block shaped our idea of home and neighbourhood.
By 1990, the average new block had shrunk to 600 sqm, while house sizes had increased to 250 sqm. In 2005, land size had decreased to around 400 sqm, whereas house size had grown to 325 sqm.
Based on recent sales within 20km of each capital city, about 91% of home sales were positioned on land blocks less than 1,000sqm. In the larger cities, the proportion is much higher, with 94% of home sales within 20km of the Melbourne CBD being on a block of land less than 1,000sqm, 93% in Brisbane and 92% in Sydney.
This reflects the growing scarcity of land, the rising need to create more affordable housing and our evolving lifestyle preferences where more households prefer lower maintenance, smaller blocks.
Average land areas will more than likely continue to fall across metropolitan areas of Australia. And even as average house sizes continue to rise and McMansions continue to be built, these days, on average, relatively few Australians live on the traditional quarter-acre block.
