Fair Lane was the estate of Ford Motor Company founder Henry Ford and his wife, Clara Ford, in Dearborn, Michigan, in the United States. It was named after an area in Cork in Ireland where Ford's adoptive grandfather, Patrick Ahern, was born. The estate along the River Rouge included a large limestone house, an electrical power plant on the dammed river, a greenhouse, a boathouse, riding stables, a children's playhouse, a treehouse, and extensive landmark gardens designed by Chicago landscape architect Jens Jensen.

The pool is now covered over and serves as an event and meeting space. It had formerly housed a restaurant. Landscape The powerhouse had its cornerstone laid by Thomas Alva Edison. The building included the estate's garage and, on the upper level, a laboratory where Ford worked on engine designs. It is also built of limestone in the Prairie Style. The hydropower not only powered the estate, but a part of the town of Dearborn as well. Jens Jensen employed his "delayed view" approach in designing the arrival at the residence. Instead of proceeding straight to the house or even providing a view of it, the entrance drive leads visitors through the estate dense woodland areas. Bends in the drive, planted with large trees on the inside arc of the curves, gives a feeling of a natural reason for the turn, and obscures any long view. Suddenly, the
