A small estate of houses first depicted on the 1972 6 inch OS map. Previously only a few larger detached houses had been built in the area. The first edition map of 1855 shows a few settlements, probably farms. The area is labelled as 'Upper Crabtree'. Crabtree first appears in the Sheffield parish registers in 1699 (Smith 1961; Scheduled Ancient Monument 215). Legibility is fragmentary as the development is bounded by old roads.
