Located in the one of the most iconic and highly sought after addresses in the West End, Carlton House Terrace is an exclusive address formed by the John Nash designed grand houses fronting The Mall and St James’s Park with private Waterloo Gardens to the west and St James’s Park to the south.

St James’s is one of the oldest London districts with a rich history and boasts some of the capital’s most exclusive and internationally renowned retailers, restaurateurs, hotels and private members clubs. St James’s appeal is further contributed by the area’s expansive array of public green spaces provided by the Royal Parks, including St James’s Park, Green Park and Hyde Park.

Carlton House Terrance benefits from excellent connectivity, being located only an eight minute walk from the extensive underground and national rail connections of Charing Cross Station and easily accessible by a range of alternative transport options.



Internationally acclaimed architectural practice Rogers Stirk Harbour + Partners will enhance the 1970s St James building, delivering an additional three floors and offering a total 162,000 sq. ft. of commercial space across 11 storeys. Set to be delivered in 2023, the commercial build will introduce a future-proofed office environment that promotes a healthy workspace inspiring collaboration and creativity and in turn, caters for a post-pandemic market.


Upon arrival at the refurbished building, future tenants will be met by a 2,700 sq. ft. double height reception leading directly to a new glazed lift-group connecting all floors and overlooking a 1,200 sq. ft. triple-height top-lit atrium

The carefully considered scheme includes a landscaped courtyard open to both tenants and the public at level 1 and views over neighbouring Waterloo Gardens. Tenants of the three additional stories will benefit from floor to ceiling glazing and 8,000 sq. ft. of extensive garden terraces on levels 8 and 10 – a result of the building’s reimagined stepped form – providing panoramic views across central London.

Enhancing the calibre and performance of the existing office space, the adaptive reuse and office extension will make way for a wealth of amenity offerings. Reconfigured basement levels allow for the addition of wellness and gym spaces, dressing rooms, bicycle storage and underground car parking.
