Medieval settlement was mainly around the two hamlets. At Church Acton most of the farmhouses lay along the Oxford road or Horn Lane, with only a few outlying farms. Friars Place Farm at the north end of Horn Lane and the moated site to the west, occupied until the 15th century, were early farms. East of Friars Place farm were commons: Worton or Watton Green and Rush green in the 16th and 17th centuries, and Friars Place in the 18th century, where there was some settlement by 1664. To the north-west were Acton or Old Oak wells, known by 1613. In the parish's extreme south, a few farmhouses on the northern side of Acton common or Acton Green were mentioned as in Turnham Green until the 19th century and were linked more closely with that village than with Acton. "Gregories", mentioned in 1551 as a copyhold tenement with 30 a. near Bollo Lane and the Brentford high road, probably lay in Acton.
