Enquire about this venue


This impressive Grade II listed venue, located in historic Whitehall, is one of London's most prestigious conference and banqueting venues. With various size event spaces, you have plenty of choice!


There are few venues in London as prestigious as One Whitehall Place. Our dedicated meetings and events facilities, adjacent to and connecting with The Royal Horseguards Hotel, offer a truly magnificent space and atmosphere. One Whitehall Place’s high ceilings, grand marble staircase, glittering chandeliers and spectacular views over the river Thames and the London Eye creates an unforgettable backdrop.

Our largest space is the dramatic Gladstone Library. An extravagant Victorian ballroom retaining a wealth of unique original features; it can accommodate up to 250 guests. We also have several large suites, plus further meeting and event rooms suitable for board and team meetings, training sessions, presentations, interviews and private dining. All rooms are air conditioned.

The Gladstone, Reading & Writing Rooms have subtle back lighting, while the Terrace Room has direct access to our outside terrace for alfresco functions. The Cellar provides a unique setting for an intimate party.

Your catering and refreshment choices are as vast and sumptuous as the rooms themselves, all of which are ideal for anniversaries, birthdays and other occasions; you can also hire the space and make your own catering arrangements.
