The shortlist for this year's Gulbenkian Prize, which awards £100,000 to the museum or gallery showing the most impressive display of innovation and imagination, has been announced.
Four finalists have been chosen from a mix of architectural practices, including international heavyweight BDP, conservation expert Purcell Miller Tritton, and Long and Kentish in association with Colin St John Wilson.
A list of 10 was whittled down to the finalists, including BDP's Kelvingrove Art Gallery and Museum in Glasgow, which saw a £35 million restoration of Glasgow's famous gallery that was also nominated for this year's Doolan prize.
One of two entries by Purcell Miller Tritton is a £19 million transformation of Weston Park Museum, part of Sheffield's Galleries and Museum Trust, which was created with the help of the local community.
The practice's second entry is a treatment of George III's country retreat Kew Palace, which has been fully restored and recreated for visitors.
The final firm up for the £100,000 prize is Long and Kentish for Pallant House, home of one of the best collections of Modern British art, which had an £8.6 million extension created and designed with Colin St John Wilson.
The winner of the coveted prize will be announced on 24 May at the RIBA headquarters in London.by Richard Vaughan
