Sion House just off the main street of Sion Mills was the home of the Herdman family,- owners of the mill and builders of the village. This illustration is based upon a 1950’s photograph. Today, it has lost its chimneys and glazed conservatory. The half timbered nature of the building is a result of a remodelling of a previous Italianate villa by London architect W. F. Unsworth in 1884
