About airspace development

Apex Airspace Development converts unused ‘airspace’ above residential, commercial and public building rooftops into new homes – helping address London’s housing shortage.

We purchase airspace rights from private property owners, local councils and housing associations and convert the space into apartments – generating potential high returns for property investors and freeholders.

This development also adds value to the whole building through refurbishment of worn facades and improvements to the property entrance and common areas.

Why airspace

  • Sell the airspace above your property rooftop and earn a significant financial payment, linked to the development potential of the property
  • Generate potential additional ground rent
  • Improve the building fabric and kerb appeal – and value of the overall building
  • Eliminate future roof area maintenance and costs
  • Help remedy London’s housing shortage

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.
