Sheppard Robson has won planning permission for its radical redesign of six buildings occupied by engineer Arup. The design links six 1960s buildings in London's 'Fitzrovia' to create a 20,600m 2'campus' for the engineering giant's 1,500 staff. One building will be demolished, while the rest will undergo a major reconfiguration. A series of coloured, curved 'hubs'will project through the 1m-thick triple-glazed facade to break up the rhythm of the structure. The hubs, located next to the existing stairwell and lift cores, will serve as meeting rooms, break-out spaces and cafes. Building work will be in three phases, with phase one set to begin later this year. 'We really wanted this job and were very honoured to get it, 'said design director Graham Anthony. There are also proposals to link the two main blocks with a third-storey bridge straddling Fitzroy Street, subject to further approval from Camden council.
