Prideaux House was built in 1808 for Sir John Colman Rashleigh. It is a square granite block of three by three bays and has a double depth plan. Above the stairwell is a rectangular lantern. The service wing to the rear is of the same date. Behind the house on higher ground is the earlier Prideaux manor house, Prideaux Old Manor. It was built in the 16th century but has been much altered since then and in the 19th century was used as stables.
