A two-storeyed rubble-built house with a central stair, dormered attic, and a cellar, Trygarn was probably built shortly before 1730 but has been alter later. The cellar extends under the south of the house with a wide fireplace at its southern end, perhaps incorporating an earlier, possibly thirteenth-century house.
