Devereux Architects has worked with LSHTM over the last 10 years on the strategy for its Grade II-listed headquarters in central London, which is arranged around two external courtyards. A seven-storey freestanding extension has been built in the north courtyard (phase 1), using existing facades on three sides as the primary enclosure. The aim was to deliver flexible, open-plan research accommodation with daylight for all levels. For the south courtyard (phase 2), Devereux has designed lecture theatres, teaching spaces, research offices and a café. The scheme includes the replacement of the existing 1920s lecture theatre with a new subdivisible 294-seat facility and a smaller 95-seat theatre within the heart of LSHTM.
