West Seaton House is a listed building of late Regency design, situated approximately one mile (1.6 km) to the east of Arbroath in the parish of St. Vigeans, in the county of Angus in Scotland.

In 1840 farmlands at West Seaton were owned by the trustees[1] of Thomas Renny Strachan of Tarry[2] who was a descendant of Sir David Carnegie of Kinnaird.

The trustees engaged the Dundee-based architect David MacKenzie I,[3] who was regarded as a very competent Gothic designer,[3][4] to produce plans and specifications for a house to be called West Seaton Farmhouse.

[citation needed] The house is of classic design with two-storeys, ashlar walls in the local pink sandstone, a slate roof and a projecting porch.

On 11 June 1971 the house was category B listed by the Secretary of State.
