There are plenty of opportunities throughout the capital but providers should understand it is not like building on a cleared site.

You can think of rooftop development as a new-build project with its foundations many metres in the air and as the extension of an existing building.

The solution requires an innate understanding of what is effectively regeneration of a building with occupiers still in place.

Pellings has created a 10-point plan to help social and private landlords to consider whether such schemes are viable.

A one-storey extension could provide as many as 180,000 new homes in London.
