73 Waterloo at St John's is a Grade II* historic venue within the iconic St John's Church on London's South Bank, moments from Waterloo Station. Recently transformed by Eric Parry Architects, it combines soaring heritage features with modern infrastructure and flexible layouts. The spectacular Nave accommodates 500 standing or 270 dining guests, while the atmospheric Old Crypt, Forum, Foyer, and breakout rooms support multi-space events from conferences and product launches to corporate celebrations and receptions. Natural daylight, built-in AV, Wi-Fi and in-house catering are available throughout. Outdoor spaces welcome garden events and standing receptions. The refurbishment prioritises sustainable design, with solar technology and heat pump infrastructure supporting net-zero carbon ambitions by 2030.
