Following the industrial era, both Giffnock and Clarkston evolved as very pleasant, suburban housing areas. The Greenbank Estate on the edge of Clarkston is a National Trust property dating from the 18th century with a magnificent mansion house and walled garden.

The house, garden and estate were built for Robert Allason who was a local businessman who made most of his fortune after joining the Virginia Tobacco Merchants. He began the building in 1764 but it wasn't finished until 1771 because of design changes.

Robert Allason didn't enjoy the estate for long as he fell into debt in 1773 and the American War of Independence ruined his fellow Virginia merchants. By 1784 he was forced to sell Greenbank and move to a small property he owned in Port Glasgow where he died in 1785. 

Much of early Clarkston was in the hands of the Maxwell family and the very popular Williamwood Golf Course was originally part of their estate.

The houses on the Oval, Clarkston were built on what was the ground of Stamperland Farm in the 1930's as part of a housing boom, which transformed mainly agricultural land into a residential suburb. The land was also initially part of the Williamwood estate owned by the Maxwell family.
