Description
Blenheim House is a farmhouse that has been converted into a house. It dates from the early 17th century and was encased and enlarged in the late 17th century. The building features render on stone uncoursed rubble on the ground floor to the right, painted brick, and an old plain-tile roof that is half-hipped to the right. There is a brick ridge stack located to the left of the center.
The house is two stories tall and has a three-window range. To the right of the center, there is a four-panel part-glazed door that is sheltered by a 19th-century timber open porch. On the ground floor, there are two-light wood casements to the left and center, and a 20th-century single-light casement to the left of the center. To the right, there is a 19th-century three-light wood mullion and transom window. On the first floor, there are two-light wood casements to the left, center, and right. The interior has not been inspected.
