An historic building record of a range of agricultural buildings located to the east of, and formerly within the curtilage of, the Grade II listed house Northfield. It is also in the Belper and Milford Conservation Area and the Derwent Valley Mills World Heritage Site. The range began as a single cowhouse, built around 1835, which gradually extended eastwards developing into an outfarm comprising stable, loosebox, cowhouse, possible dairy and pigsty by the 1950s. In Derbyshire, notably the Peak District, outfarms are most common in areas of planned enclosure from medieval open strip fields, wastes and common. The outfarm to the rear of Northfield is no exceptions with a number of the fields immediately east being long and narrow which generally have reversed 'S' curved boundaries indicating that they were formed by enclosing pre-existing medieval open strips.
