This polygon, which now features low density light industrial units, represents the area shown as residential Hillfoot on the 1851 OS plan. Hillfoot appears to have developed as a residential suburb on the outskirts of the growing city in the mid 19th century at the point at which the turnpike road to Halifax leaves the built up area. By 1891 the area was filled with high density, mostly back to back housing. Since the 1984 OS plan of the area Penistone Road has been re-routed along the western boundary of the Hillfoot area as part of the widening works that produced the dual carriageway known today.
