Completed in 2018, the building has been redeveloped and refurbished to the highest of standards, blending the design of the Grade I listed façade and modern architecture.

The property, 20-21 St. James's Square comprises two interconnected buildings: a historic 1774 section designed by architect Robert Adam, and a 1930s extension with a 1990s addition (originally designed in the 1930s by Mewes & Davies, who also designed The Ritz). The Robert Adam-designed building is a Grade I listed structure, the highest level of landmark protection afforded.

61,381 sq ft (5,702.5m2) of Grade A offices arranged over lower ground, ground and six upper floors.

The 6th-floor benefits from a private 763 sq ft roof terrace, and the ground floor from a private courtyard.

Amenities include six underground car parking spaces, 82 secure cycle spaces accessed separately from Cleveland Place, 136 lockers, drying room and shower facilities.

Located in the heart of London's West End, St. James's is one of the most valuable real estate areas in the U.K. and is widely regarded as one of London's most prestigious headquarters office addresses. 20-21 St. James's Square benefits from substantial frontage on St. James's Square and proximity to the Piccadilly and Green Park Underground stations, as well as the Jubilee, Bakerloo, Victoria and Piccadilly subway lines.
