Smith Square City Of Westminster SW1P 3HA
The proposal seeks the refurbishment and alteration of the Grade I listed Smith Square Hall to address urgent conservation needs and secure its long-term sustainable use. The works will include structural masonry repairs to safeguard the historic fabric, the refurbishment of the Main Hall, and improvements to accessibility and circulation throughout the building. All mechanical and electrical services will be replaced to enhance energy efficiency and facilitate a transition from gas to electric systems. Smith Square Hall currently accommodates a Concert Hall, Restaurant, and ancillary uses. Within the building is a residential unit that is no longer fit for purpose. As part of the application, a minor change of use is proposed to allow this space to be reclassified from C3 Residential to Sui Generis community space, supporting wider public access and engagement.
