New Permitted development rights - Building upwards

The new permitted development rights are set to change the building scenery in London.

What are precisely the new rights?


Starting from the end of August 2020, a brand new permitted development right is allowing homeowners to build up to additional storeys to an existing dwelling consisting of at least two storeys or an additional storey when the existing dwelling is already one storey.

-Where the existing house already been enlarged under permitted development or otherwise by an additional storey

Other restrictions:


-Total height with the extensions not to be more than 18m in total.

-For one storey the additional height not to be more than 3.m in total (in a bungalow you can build only one storey on top no more than 3.5m high including the roof).

-Build no higher than 3.5m from the highest part of the roof for semi-detached properties which shares a party wall and for terraces, every other building in the same row

-The structural elements should not be visible

-In walls or roof slopes no windows allowed and the pitch of the principal part must be the same

-As in every planning application, the condition is that the materials should match the exiting
