Project Description
CoyEagle Architects advised on the planning application for 139 Piccadilly — Lord Byron's former home — a substantial Mayfair townhouse at one of London's most prestigious addresses. The approved scheme involved a comprehensive change of use from its former classification to a single-family residence under Class C3.
The scope of works demonstrates the complexity of consented development in this part of Westminster: sub-basement level excavation, a rear basement extension, lightwell extensions at second- and third-floor level, installation of a roof-level plant room with lift and overrun, and the creation of a new roof terrace and rear courtyard.
CoyEagle's expertise in navigating the planning and legislative requirements of a Central London listed and conservation context was central to securing a successful outcome for the client. The project illustrates the practice's ability to operate at the highest level of the residential market, managing complex consent strategies with precision and care.
