A rare opportunity to secure a ground floor retail unit within Radiant House, a striking Grade II listed building in the heart of Fitzrovia. The unit benefits from excellent natural light and strong street presence, with large arched windows providing an attractive frontage and creating an inviting retail environment. Inside, the space retains original timber flooring and generous ceiling heights, while a skylit rear section adds further brightness and flexibility to the layout. The character of the building, combined with the open and adaptable floorplate, makes the space particularly well suited to a premium retail concept, showroom or gallery, offering brands the chance to create a distinctive presence within one of the West End's most established and creative neighbourhoods.
