The deal will see Apex Airspace take forward the pilot project with limited financial input from the council in the initial phase of the what is being hailed as a new model for private airspace development in cities.

The public-private partnership ‘airspace’ project will deliver modular rooftop homes on two extra floors across seven existing three-storey blocks.

This will enable Harrow Council to increase affordable housing capacity at reduced costs, while providing minimal disruption to existing residents.

Together with affordable airspace homes, the proposed development works will include enhancement of the communal areas and improved amenities for all residents to benefit.

Harrow council’s first ‘airspace’ project will be at The Berridge Estate in Edgware.

Cllr Phillip O’Dell, Portfolio Holder for Housing, Harrow Council, said: “We’re excited to be working with Apex Airspace on this new project, helping provide vital new affordable homes using modular construction.

“We’ve submitted a bid to the GLA for funding for further airspace developments, at sites yet to be determined. We will be consulting residents on a local lettings policy for the scheme, which could allow existing tenants to move into the new homes.”

Arshad Bhatti, chief executive of Apex Airspace, said: “This is a sign of monumental progress in the use of airspace development for local authority affordable housing delivery.

As the need for affordable housing is on the rise, many providers – including Harrow Council – are seeking innovative opportunities and solutions to expand their portfolio without the need for new land or demolition.
