Design concerns
Westminster Council recently rejected a flat extension proposal due to design concerns, particularly its impact on a conservation area.
In October 2025, Westminster Council's Planning Sub-Committee rejected a proposal by Capital Services to extend a flat at 2 Chesterfield Street. The decision was made due to design concerns and the potential impact on the Mayfair Conservation Area, highlighting how aesthetic and functional aspects of proposed developments are scrutinised by planning authorities.
The application sought to create a separate lower ground floor flat, remove and recreate the roof structure, and add a sheer extension to the fourth floor. A separate listed building application also addressed internal reconfigurations, with the Director of Town Planning involved in the assessment.
