Why Airspace Development?

Now a well-established approach to development, when coupled with the financial windfall it can create for property owners, there is significant all-round appeal.

Apex are the most experienced airspace developer and innovator in the sector, Our quality approach has been recognized through winning of a wide range of national property Awards: Best Innovation, Best Newcomer, In 2018, our innovative approach resulted in Apex being invited to a roundtable meeting with the Prime Minister on new housing innovations.

Airspace development combines strong environmental, logistical and quality proof points. It is sympathetic to the environment, relies on off-site construction methods that reduce disruption to the existing community and adopts an approach whereby quality is controlled and assured – all whilst creating new value. It helps address the funding gap associated with meeting housing targets through the re-purposing of existing assets which hold significant new value potential.


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

Combined with advanced offsite modular construction, airspace development offers a unique solution to develop new and affordable homes in urban areas of tight density and land supply, in almost half the time it would take to undertake a traditional build, with minimal disruption to the existing residents and local community.


New technology, meanwhile, can calculate both the extra weight a building can bear, as well as identify the most suitable rooftops for new homes of this type.

  • Windfall payment, linked to the market value
  • Reduction of maintenance expenditure, as a result of removal of the roof liability and associated communal costs
  • Improvements in kerb appeal, and external façade
  • New and renovated communal facilities including lifts, stairwells, entrances, storage and external landscaping
  • Creation of new ground rent income for the freeholder
  • Increase in capital values to Leaseholder properties underneath and a significant reduction in service charge costs
  • 50% reduction in construction time & 90% fewer vehicle journeys
  • Quick installation provides minimal disruption to local residents
  • Certainty of build delivery programme and cost
As a small organisation, we have very limited land and we don’t have vast reserves of money. Working with Apex helps us manage the risk around a large project like this. We hope this becomes a model for other small housing associations. when they see what we’ve been able to achieve

Our experience of working with Apex has been excellent. Building trust and implementing a transparent relationship is really important to us - that’s something we have had from the outset.
