In June 2020, the Government announced an update of The Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended) (GPDO) in a new 20th Part, allowing for the construction of new flats in airspace on a variety of buildings throughout England.
For developers and landlords looking to capitalise on the opportunities available to existing housing stock or commercial premises, permitted development rights (where planning permission isn't required) has created new possibilities to quickly unlock the potential of buildings - especially in our urban centres.
Airspace developments refer to the construction of homes built within the 'air rights' of existing buildings, typically extending around two levels up from the current building. In simple terms, this means an upwards extension on the roof of a building.
Part 20 of the GPDO permits the construction of new flats in the airspace of different types of commercial and residential buildings, providing additional opportunities to create dwellings in built-up areas.
Here are the key criteria to keep in mind:
So it’s eyes off the ground and into the sky as we explore the hidden opportunities that can be found in the space above buildings.
Here’s a quick overview of the six permitted development types that allow airspace development:
Class ZA allows for the demolition of a commercial building or a block of flats to be replaced by an individual block of flats or a detached house within the footprint of the old building, with an upward extension of up to two additional storeys in the airspace.
Class A permits the construction of two additional storeys of new flats in the airspace above detached blocks of flats.
Class AA permits the construction of up to two new storeys of flats in the airspace above detached commercial or mixed-use buildings.
Class AB allows for new flats on terraced or semi-detached commercial buildings - even those that already have flats above.
Class AC permits the construction of new flats in the airspace above terrace homes (including semi-detached houses).
Class AD permits the construction of new flats in the airspace above detached houses.
While each PDR Class differs, it's worth noting that none are permitted on Article 2(3) Land - including conservation areas. Additionally, all prevent the creation of HMOs in the future without full planning permission and do not apply to properties that already contain an HMO.
