As we move further into 2026, the traditional quarter-acre block is increasingly becoming a thing of the past. With Australia’s national housing target of 1.2 million new homes, there is a growing shift towards three- and four-storey developments as a short-term response to housing shortages in Sydney, Newcastle, and Wollongong. At Flash Conveyancing, Julian and Renee are witnessing a rise in “vertical infill”, where new residences are constructed above existing apartment and commercial buildings. This approach is both innovative and necessary in addressing housing supply, provided that appropriate safety standards are maintained—particularly given concerns from the past decade.
The purchase of airspace involves developing above an existing strata building to add new apartments. The advantages are threefold: existing owners may receive funding for essential building repairs, cities can increase housing supply without expanding into greenfield areas, and modern construction methods—such as cross-laminated timber (CLT)—allow for lighter, faster, and more efficient building.
Recent regulatory reforms are also raising standards. New high-rise developments are expected to include stronger oversight, such as independent certification, enhanced compliance processes, and long-term defect liability measures. These requirements are designed to improve building quality and safety outcomes prior to occupation.
Infrastructure remains critical to supporting these housing targets. Transport-oriented development (TOD) hubs such as Rockdale, Lidcombe, Macquarie Park, Newcastle Interchange, and North Wollongong are expected to play a key role in supporting higher-density communities. With appropriate investment in infrastructure—such as transport, public spaces, and essential services—these emerging vertical communities can become more liveable, sustainable, and resilient.
Affordability may also improve through building upwards. Maximising height reduces the land cost per dwelling, while construction costs are shared across multiple units rather than a single dwelling. This can allow for better allocation of resources towards design quality and safety features, potentially improving outcomes for first-home buyers.
Recent developments in construction materials and processes are also contributing to efficiency. Modern lightweight materials are less prone to moisture and mould issues, and advances in construction methods are enabling faster project delivery. However, planning and approval processes remain a key factor in overall timelines.
Flash Conveyancing Advice
Legal protection is essential in emerging vertical communities. For strata and airspace purchases ensure appropriate insurance protections, including long-term defect coverage where available. Confirm that contracts incorporate clear contractual protections that remain effective through to settlement.
