This landmark on the south bank is a world-renowned multi-venue arts and culture centre, comprising the Royal Festival Hall, Queen Elizabeth Hall and the Hayward Gallery. While the latter two are currently undergoing significant refurbishment that will see them reopen in early 2018, the Royal Festival Hall is very much open for business, making an impressive space to host large-scale, special-occasion conferences and product launches. St Paul’s Roof Pavilion on the sixth floor is the place to book for smaller groups who want the views. There’s plenty of brutalist architecture to enjoy through the floor-to-ceiling windows, while its balcony provides a fetching breakout space. We like the idea of the intimate Weston Roof Pavilion which works well for laid-back business gatherings or brainstorming sessions.
