M273 Treeshill, Bridge of Weir

This four-bedroom, detached, roughcast house was built in the prosperous Renfrewshire commuter village of Bridge of Weir for David Simpson Morton, of Williamson, Morton & Co., a Glasgow firm of oil merchants, paint and colour manufacturers.

Authorship: Treeshill was included on a list of Mackintosh's works compiled in the 1930s by Ronald Harrison, an early student of his architecture, who had access to the office records. Harrison evidently believed that Mackintosh contributed in some way to the design of the building, but no evidence has come to light to support this attribution. The drawings submitted for planning approval were signed by John Keppie.
