Touch House is a country house located 4 kilometres (2.5 mi) west of Stirling in central Scotland. It stands at the foot of the Touch Hills, on the south side of the River Forth. The house incorporates a 16th-century tower house, but its present form dates to the middle of the 18th century when the south facade was added, described by Historic Scotland as “Probably the finest Georgian elevation in the County of Stirling.” Source – Touch House.
As I was in the area I went to have a quick look. It was raining so only managed a few photos. I don’t know if the house is open to the public though some of the buildings are used as a business centre.
Update – Touch House is a private residence though the stables are a business centre. The photos I took of the house are from the drive where I got a good view of the house without invading privacy.
