Sale Notes
The Diorama presents a rare opportunity to acquire one of London’s most historically significant buildings, ideally situated on the southern boundary of Regent’s Park. This Grade I listed property offers the perfect blend of architectural heritage and modern flexibility, with planning consent previously secured for comprehensive redevelopment, including a new floor and roof terrace, allowing an investor to reposition and unlock the site’s full value.
Originally conceived in 1823 as Britain’s first purpose-built Diorama, the property retains a striking Regency façade, paired with an expansive internal atrium providing abundant natural light. The building spans six levels, incorporating triple-height space within a unique polygonal footprint, creating scope for both adaptation and contemporary design. Offered with full vacant possession and a long leasehold interest extending to August 2144 at a peppercorn rent, this asset promises exceptional appeal for owner occupiers, investors, and developers.
With alternative uses possible subject to necessary consents, this versatile property supports future repositioning into luxury residential, boutique hotel, members’ club, or cultural institution, capitalizing on its premier West End location and proximity to London’s knowledge and healthcare clusters. Positioned between Regent’s Park and Fitzrovia, it benefits from unrivalled transport connectivity, five Underground stations within walking distance, and a setting amidst London’s most prestigious addresses.
