One of Europe's most eco-friendly buildings in Norwich has added to its impressive tally of awards.

The Enterprise Centre at the University of East Anglia has scooped a national accolade from the Royal Institute of British Architects (RIBA), after winning three RIBA East awards last month.

RIBA national awards are given to buildings recognised as making a significant contribution to architecture.

Judges said the Enterprise Centre 'exudes a sense of calmness' and is a 'tour de force in the exploration and use of sustainable materials but also a remarkable place to work and to enjoy'.

The building, which celebrates its second anniversary this summer, now holds 26 awards.

Prof John French, chief executive of the Adapt Group, based at the Enterprise Centre, said: 'Architecturally, RIBA are the most significant awards for us and even to have won the initial three regional awards was a huge achievement.'
