Our Mayfair Events Venue
No.4 Hamilton Place is a beautiful Edwardian townhouse in the heart of Mayfair. Our Grade II listed building is steeped in history and was once home to the Duke of Wellington. As a venue, we offer a variety of versatile event spaces including a fantastic outdoor roof terrace, a conference room with in built AV and beautiful reception rooms as well as a grand sweeping staircase.
In 1938, No.4 became home to the Royal Aeronautical Society which is the world’s only professional body dedicated to the entire aerospace community. Established in 1866 to further the art, science and engineering of aeronautics, the Society has been at the forefront of developments ever since. As well as having their headquarters on site, the Society regularly hosts events at No.4 including conferences, meetings, receptions and dinners.
