Corston Farm, Morton Reservoir, Muireston

2 storey 3 bay rubble farmhouse with ashlar quoins and dressings, and single storey extension to the side. The various ancillary outbuildings are of 1 or 2 storeys, most with their slated and pantiled roofs missing. A long L-plan complex comprising a 2 storey barn with 3 double door entrance bays, and a row of 3 single storey buildings, sits behind.

Appears in its current layout on the 1st edition OS map (1852) with a threshing machine abutting the West elevation. The Map of the County of Edinburgh by Greenwood, Fowler & Sharp of 1828 suggests the farm consisted of a U-shaped steading with separate farmhouse sited to the East. The current buildings may incorporate earlier structures or materials.
