Provan Hall has a boundary wall dating from 1647. The coat of arms of the Hamilton family, which at that time owned the estate, is found above the entrance arch of that wall. Across the courtyard to the south is Blochairn House, which today is occupied by the Greater Easterhouse Environmental Trust. Thought to have been built around 1450 Blochairn House was remodelled in 1760 by John Buchanan, a Tobacco Lord, to resemble the plantation house on his Jamaican tobacco estate. Both Blochairn and Provanhall are category A listed by Historic Scotland (1970). The houses were served by the now Provanhall Loch, now artificially banked and part of Provanhall Park. A formal parterre garden is to the north of both listed buildings. Provanhall is now the headquarters of the local preservation trust.
