has been followed by other architects. His father designed St John's Methodist Church, and he was responsible for many of the school's buildings, as well as others in the vicinity, and further afield in North Wales. This led to the area that includes the school being designated as Colwyn Bay's first conservation area. Evacuation of Rydal School During the Second World War, the main campus of Rydal was occupied by the Ministry of Food. The school was evacuated to Oakwood Park, a small country estate 2 miles west of the town of Conwy. The school returned to Colwyn Bay in 1946. Evacuation of Penrhos College During the Second World War, the Penrhos College site was taken over by the government for Ministry of Food use. The Duke of Devonshire, anticipating that schoolgirls would make better tenants than soldiers, offered Chatsworth House for the use of the school. The contents of the house were packed away in eleven days and 300 girls and their teachers moved in for a six-year stay.

The girls grew vegetables in the garden as a contribution to the war effort.

The former Penrhos Junior and Lyndon campuses were disposed of and staff and students were relocated to the larger existing Rydal Preparatory School campus. In 1999, Rydal School and Penrhos College agreed to merge as Rydal Penrhos School. Initially they were run as three separate divisions: "preparatory", "girls" and "co-educational", reflecting the three formerly separate incarnations.

The merger and integration was not without controversy, not least over the sale of the former Penrhos site and the restructuring of the staff.
