More than 15,000 visitors to a regional roadshow were polled on their favourite new buildings from the past 50 years.
The roadshow, organised by the Royal Institute of British Architects (RIBA), stopped at 16 venues in the East Midlands over the past year.
Visitors were asked to pick their favourite buildings from examples put forward by the organisation.
Built in 1963, Nottingham Playhouse was one of the oldest buildings in the exhibition.
The theatre’s bold design has proved popular with visitors over several decades and was bolstered by the addition of Anish Kapoor’s Sky Mirror sculpture in 2001.
Stephanie Sirr, Chief Executive of Nottingham Playhouse, is delighted to be recognised in this poll: ““Nottingham Playhouse was an iconic building when it was unveiled in the early 1960s and we’re delighted to see Peter Moro’s groundbreaking design is still admired today.”
Mike Baulcombe, Regional Director of RIBA, said, “This exhibition has proved a tremendous success in raising awareness of the superb contemporary architecture we have here in the East Midlands.”
