J N Bentley New

Project Brief

Following the devastating floods in June 2007, J N Bentley were tasked with the new flood defence project. The museum shows a history of the area’s steel and cutlery industries and house’s the 12,000 horse power River Don Engine built by the Davy Brothers of Sheffield in 1905. The shocking floods of 2007 had threatened the exhibits with permanent damage and closed the museum for about 18 months.
