Gattonside House is a 19th-century
country house in Gattonside, built between c.1808–1811 in the
Classical style. The earliest recorded owner is
James Brown (d. 1816), owner of a Jamaican coffee plantation. The house was occupied between 1821 and 1824 by
Sir Adam Ferguson, Deputy Keeper of the Scottish Regalia and close friend of
Sir Walter Scott. The following owner of the property, retired banker George Bainbridge (c.1788–1839), employed local architect John Smith to enlarge it. On Mungall's death, the property was sold to Edward Ebsworth (c.1848–1915) who commissioned
Robert Lorimer to extend and alter it. following which it was owned by Captain Francis Montgomerie (1887–1950), younger son of the
Earl of Eglinton and Winton, whose family left in 1951. Following a brief period of occupation by
John Morgan, the property was bought by the
Brothers of Charity, who ran the house as St. Aidan's Care Home for the Mentally Handicapped from 1953 until 2009. From the institute's departure in 2009, the property fell into a state of disrepair, and as of 2024 it was estimated that replacing the damaged roof alone would cost £850,000. The house was designated as a Category B listed building on 15 March 1971 as "a well-detailed early 19th-century Classical villa". == Notable residents ==
