Two years ago, there was a drive to promote the utilisation of roof spaces for residential development, to help alleviate the shortage in housing supply. Reports and articles were written and feasibility studies undertaken. So what has happened since then and has the initial enthusiasm been overtaken by a reality of the difficulties these developments pose in providing a viable proposition.


Come and join us as our expert panel discuss:


  • What is the potential capacity of airspace development?

  • What types of development are viable?

  • What are the key drivers?

  • What are the key challenges?

  • What challenges are posed by the planning system?
