Windmill Hill is located in a rural setting of southeastern Dublin, on the south side of Windmill Hill Road. It sits on about of land, which slope steeply away from the road to the southeast, providing views of Mount Monadnock and the hills of Peterborough. It is a -story wood-frame structure built in a U shape with gabled roofs and shingled exterior. A rubblestone terrace wall provides a level grassy area behind the house. Its windows are six-over-six sash throughout, and there are gabled dormers piercing the roof of the central section.
