Purcell Miller Tritton, Long & Kentish and BDP have made it onto the short-list for the £100,000 Gulbenkian architecture prize.

Purcell Miller Tritton’s £19 million transformation of the Weston Park Museum and the restoration of Kew Palace, George III’s country retreat, are competing against BDP’s £35 million New Century Project at the Kelvingrove Art Gallery, and an £8.6 million extension to the Pallant House Gallery in Surrey by Long & Kentish.

The winner of the coveted award will be announced on May 24.
