Residential Extensions and Alterations Design Guide Supplementary Planning Document (SPD2)

The SPD seeks to provide updated advice specific to residential extensions. It takes account of extensive changes that have occurred to residential permitted development rights since the Council’s previous guidance was adopted in September 2002. It seeks to balance the demand and needs of homeowners who want to extend their homes, with ensuring that the character of Brent is maintained or enhanced.
