Further afield, in what is now Cumbria, he designed country houses such as Holehird in Troutbeck (1854), Wynlass Beck in Windermere (1854), and Parkside in Kendal (1865). He also designed a school for his home town of Alderley Edge. Crowther was appointed as the diocesan architect for Manchester Cathedral. His restoration of the cathedral is considered by the "Buildings of England" authors as "his final great work", which was incomplete at the time of his death; this occurred in March 1893.
