THE DIORAMA:
Built as an early 19th Century Diorama, the property retains its Regency façade whilst accommodating office use within its open plan internal layout.

The property forms part of a detailed and uniform stucco façade and is inscribed at roof level with ‘Diorama’, sitting slightly taller than the rest of the terrace.

The property provides a grand, double height reception with elegant symmetrical staircases leading to the first floor and benefits from entrances onto both Park Square East and Peto Place.

Entering from Park Square East, the property leads into a three storey brick-built polygonal building which extends into Peto Place. A glass roof covers a triple-height central atrium extending down to the lower ground floor, providing excellent natural light to the centre of each of the three open plan floors. The property benefits from a passenger lift, together with on-site parking.

EXISTING ACCOMMODATION:
The building has been stripped back to a shell condition

PREVIOUSLY CONSENTED DEVELOPMENT SCHEME:
In 2021, The Diorama received a resolution to grant planning permission, subject to a Section 106 Agreement, for a comprehensive refurbishment and repositioning of the building, including change of use from Sui Generis to office use, the creation of a new third floor and roof terrace, and extensive internal remodelling works.
Although the consent has now lapsed, the scheme demonstrates the significant potential to sensitively reposition this landmark building. The consented proposals sought to “peel back” later alterations and reveal the original fabric and spatial hierarchy of the historic Diorama building.

ALTERNATIVE USE POTENTIAL:
Subject to the necessary consents, The Diorama offers significant potential for a variety of alternative uses including:

• Boutique Hotel
• Private Members’ Club
• Luxury Residential
• Educational / Institutional
• Hospitality & Cultural Uses

The building’s large floorplates, exceptional volumes and landmark architectural character provide flexibility for a range of repositioning strategies. Its unique setting opposite The Regent’s Park, combined with its Grade I listed status and historic significance, creates the opportunity for a truly distinctive Central London destination asset.
