Unlock the Hidden Real Estate Above Your Building.

Airspace Connect — Australia’s Vertical Real Estate Marketplace.

Connecting building owners, strata communities, and developers to transform underutilised rooftops into sustainable housing.

What is rooftop & airspace development?

The idea in three parts — what it is, what could go there, and how owners bring a partner in.

The idea

Building up, not out.

Using the air rights above a building.

Many blocks are allowed to build higher than they do. Rooftop and airspace development uses that unused space — new homes above an existing building, with no new land.

What it takes

What could go there.

Extra floors, rooftop homes, amenities.

A storey or two, a rooftop home, a pool or a garden. Whether a roof can take it depends on the structure underneath, the planning rules above and the services running through it.

Owners & strata committees

Start with your building’s potential.

Assess the airspace, work through the 12-step Roadmap with your committee, then invite prospective joint-venture partners when your building is ready.

Developers & builders

Find the right building to partner on.

Explore assessed buildings, review zoning and height indicators, then investigate owner tenders. An assessed building is not necessarily available for a joint venture.
