The information contained in the Residential Extension Guidelines (REG) underwent 6 weeks of public consultation prior to adoption as a Supplementary Planning Document in December 2017 to the Borough’s Development Plan comprising Hounslow Local Plan 2015-2030 and The London Plan and its associated Supplementary Planning Guidance.
The purpose of these Guidelines is to provide clear advice to our customers on what the Council considers to be acceptable forms of extension to residential properties.
These Guidelines expand on the Development Plan policies and explain the many types of residential extension that can be built. In most cases, drawings show both good and bad examples of the extension type.
The acceptability of any extension will of course depend on both its size, design and position and the size, type and age of your and nearby houses, and any other relevant material consideration.
