Dalzell House is situated on a steep, rocky bank, above the Whinny Burn, about a mile from the centre of Motherwell. The original building would have been a wooden structure, followed by the stone Keep that was probably built during the 15th or early 16th century and was purchased by James Hamilton in 1647. The Keep was extended in 1649 with further substantial additions throughout the centuries that followed. A particular room known as the "the Green Lady's Bedroom" in Dalzell House is said to be haunted.
