A rich history at a Central London conference venue
20 Cavendish Square is more than a conference venue, it has nearly 300 years of history. Built around 1729 by architect Edward Shepherd, it was one of the first houses on Cavendish Square. Over time, it was home to important residents like Lord Montford, Lord Barrington, and former Prime Minister Lord Asquith.
Today, this historic venue is home to the Royal College of Nursing and offers a special setting for conferences, meetings, and events. At its heart is Cowdray Hall, where original oak doors open into a grand room full of character. The hall has three stained glass windows by Dudley Forsyth. They show Love, Fortitude, and Faith — the values of nursing. There is also a carved Cowdray Coat of Arms by George Haughton.
Next to Cowdray Hall is the Council Room. It was first designed as a dining room by Sir Edwin Cooper. Now it is used for networking, catering, and exhibitions. These spaces blend history with flexibility, making 20 Cavendish Square a unique conference and event venue in central London.
