MacCormac Jamieson Prichard has designed London's latest scheme of single-person key-worker housing, which was opened this week by London mayor Ken Livingstone and the Countess of Wessex. Friendship House in Southwark is developed and run by the London Hostels Association and provides 180 bedsits with en-suite bathrooms. Achieving a very high density of 969 bed spaces per ha, the six-storey building encloses a communal courtyard. It was built for £7.3m by Galliford Try Partnerships, with Butler & Young as structural engineer, Michael Popper Associates as services engineer and Hamilton H Turner as QS.
