Across Melbourne and much of the country, a clear trend has emerged in how homeowners are responding to a property market defined by high prices, tight stock levels and elevated borrowing costs: rather than selling up and buying into an equally expensive market elsewhere, more Australians are choosing to stay put and extend the home they already own.
The economics behind this shift are fairly straightforward. Stamp duty, agent fees, and the cost of buying into a comparable or larger property in the current market often make moving a considerably more expensive proposition than renovating or extending an existing home, particularly for families who are otherwise happy with their location, school catchment or neighbourhood. For many homeowners, the calculation now favours investing in the property they have rather than absorbing the transaction costs of moving.
This shift has been particularly visible among growing families who bought a starter home years ago and have since outgrown it. Rather than compete in a tight market for a larger property, many are opting for home extensions that add a bedroom, a second living area, or a larger kitchen and dining space – effectively reshaping their existing home around a family’s changing needs rather than starting from scratch elsewhere.
There’s also a generational angle worth noting. A growing number of extension projects are being driven by multigenerational living arrangements, with families adding self-contained spaces or additional bedrooms to accommodate ageing parents or adult children who are choosing, or being forced by the market, to stay home longer. This kind of flexible, adaptable extension work has become a meaningful segment of the residential renovation market in its own right, distinct from the more traditional “extra bedroom” brief.
From a builder’s perspective, this trend has placed a premium on extension specialists who understand how to integrate new structures seamlessly with an existing dwelling – matching rooflines, materials and floor levels in a way that makes the addition feel like part of the original home rather than an obvious afterthought. That’s a genuinely different skill set to volume home building, and one that’s increasingly in demand as extension work grows as a share of the overall residential construction market.
Cost pressures in the broader construction sector haven’t made this easy. Material costs and trade availability remain challenges for extension projects just as they do for new builds, and homeowners considering this path are generally best served by builders with deep, specific experience in renovation and extension work, rather than assuming any residential builder can pivot easily between new builds and additions to an existing structure. As affordability pressures continue to shape household decision-making, extending rather than moving looks set to remain a significant and growing part of the residential construction landscape, rather than a temporary response to a difficult market cycle.
