Charles Rennie Mackintosh’s most famous and beautiful domestic commission was Hill House. Set high on a hill in Helensburgh, this architecturally eclectic house overlooks the river Clyde. The building is unmistakable due to Mackintosh’s completely asymmetrical design. Consisting of numerous different roof levels and shapes, with the exterior derived from the interior planning – the house is truly unique. It was built for the Scottish publisher Walter Blackie as his family residence. Mackintosh was responsible for almost all aspects of the house from the exterior to much of the furniture and internal fixtures and fittings. The house is now maintained by the National Trust for Scotland. The Landmark Trust keeps the top floor available for holiday lets, well worth a visit!
