Knighton Mill, Broad Chalke    

Knighton Mill is a replacement for a former C19th mill, not listed and not apparently of any great quality. A Wiltshire Council conservation officer, commenting on the proposed new building, felt that historic waterways on the site, and their associated structures, were of greater value than the old mill itself. Much food for thought was provided for the judges by the new mill being divided into two contrasting sections – a more prominent one in traditional stonework, and behind it a very contemporary structure in glass and steel. What helped make this arrangement successful was the quality of the Bath stone ashlar in the traditional part, very carefully executed and pointed up to make the joints barely visible. The design of this front part picks up on some elements of mill design, with a projecting bay at high level which traditionally would have been used for lifting, and prominent semi-circular windows at low level. Weathering of the stonework is likely to add to the character of this part of the building as time goes on. There are some nice internal features, including a high wall of flintwork, created with individual flints rather than cast flint blocks, and above all a cantilevered stone staircase, extending across three floors and a work of superb design and execution. The whole project had clearly been based on appropriate and careful treatment of the river Ebble as it flows through the site, and under the mill building, with historic structures repaired. The river was obviously a challenge during construction, an indication of the complexities of the project, whose mastering certainly justified an award.
