Corston is situated towards the end of the unclassified road running east-west off the minor road between Hundleton and Castlemartin, and is 1.5km north-east of the latter. It is a whitewashed roughcast, small country house c.1800, with a slate roof and renewed brick end stacks. Corston has 3-storeys, a five-window front with dentilled brick eaves and 4-pane sashes to the upper floors. There is also a dentil cornice. The ground floor has two large later 19th century canted bays and at the centre a semi-circular open porch on four timber columns with moulded caps. There are double 3-panel doors with plain fanlights and a moulded wood surround. The north end service wing is of two-storey with similar eaves, a one-window range and brick north stack. The rear north-west wing has an end stack and there is a two-storey outshot between the two rear wings. Internally there are 6-panel doors, an elliptical arch to the hall with reeded pilasters, lion masks and rosettes in frieze. There is a spine corridor to the south end a plain dog-leg staircase with stick balusters and moulded rail and shaped brackets to the tread ends. The south-east front room has an elliptical-arched recess in the west wall. The house belonged to the Leach family from the later 18th century to 1936 and was probably built by Abraham Leach in 1799, when it became his residence though he did not inherit the estate until 1811. The last of the family at Corston was Brigadier-General Sir Edmund Burleigh Leach (1870-1936). It is now a hotel.
