Designed by AFLS+P architects, the 10,750 m² rectangular Wycombe Sports Centre will be clad in copper and aluminium panels that have four different finishes to give it a highly distinctive look.
The centre will be home to an eight-lane Olympic-size swimming pool, 12-court sports hall, 150 station gym, four rink indoor bowls hall and two squash courts.
The current Wycombe Sports Centre will remain open while the new leisure centre is built adjacent to it, on the current site of the running track.
The appointment is the latest in a series of projects for Willmott Dixon to build leisure accommodation across the region. Other recent projects include Acton Town Hall and an East of England centre of sporting excellence in St Albans.
