Airspace Development

The shortfall in new housing supply in London and more widely in the UK demands new ways to deliver new and affordable homes.

Airspace in London

Airspace development provides an innovative option to create new value in untouched locations, and furthermore alleviate both the financial and housing pressures for local authorities – not just in terms of new supply but also in terms of saving on roof replacement programmes for both private freeholders and public bodies.

In 2016, we conducted comprehensive research on the market potential for airspace development, which identified that the London market alone has up to some 14.5 million square metres of potential space above its rooftops and translating this into development potential suggests the potential for up to 180,000 new homes.

Why airspace?

Airspace development brings a range of benefits to not only the freeholder of an existing property, but also the residents underneath and the local community, while providing both affordable and private new housing.

  • Freeholders can sell the airspace above their property rooftop and earn a significant financial payment, linked to the development potential of the property
  • Generate potential additional ground rent
  • Significantly improve the building fabric and kerb appeal – adding value of the overall building
  • Eliminate future roof area maintenance and costs
  • Help remedy London’s housing shortage
  • Cause minimal disruption to neighbours with offsite construction

A simple approach

A free, no obligation initial evaluation assesses the potential of your property. If your property is suitable, we purchase the airspace development rights, creating windfall cash paid to you at key project milestones:

1. Once contracts have been exchanged

2. On receipt of successful planning permission

3. Upon completion of the development project

Apex takes on full risk and responsibility for the lifespan of the project – including planning permission and project management. We specialise in advanced quality offsite modular construction – mitigating disturbance to you, your tenants and neighbours – speeding up project delivery.
