The William English House is a historic farmhouse in the far western portion of the U.S. state of Ohio.

Located along State Route 47 northeast of the village of Versailles in the northeastern corner of Darke County,[1] the house was built in 1881 as the residence of William English, an astronomically-inclined farmer.

Besides farming, English operated a brickworks on his property, and his employees generally lived in the same house as his family.

Four doors and eight windows on the front (western side) of the house are placed to face exactly westward, and multiple doors on recessed porches on the southern side of the house are placed so that the sun's light illuminates them at noon on a certain day of the year.

The house's location atop a small hill overlooking State Route 47 ensures that the light of the sun is more frequently cast upon it.
