Semi detached housing estate probably dating to the 1930s. The houses and layout plan is superficially similar to the municipal estates built by Sheffield Corporation at this time however the plots are generally larger and materials and design are of a generally higher quality with more embellishments in both house and garden. Architecturally distinctive Co-Op at Lees Hall Avenue and Carrfield Avenue. This part of the estate (which is contemporary with the part separately described as HSY 2051), was enclosed land in the mid 19th century - with settlement activity firmly nucleated at settlement cores at Norton Lees (to the west around 'Bishops House' and at Norton Woodseats to the south west. The 1877 25 inch OS plan of Derbyshire shows three large residences or farms at Norton Lees, perhaps indicating an early consolidation of local landholdings. Evidence of landscaping of small parkland around Thorpe House on 1898 Derbyshire Ordnance Survey. Partial legibility of earlier field boundaries which were partially retained and influenced the pattern of development of this estate. Earlier boundaries suggestive of piecemeal division of larger units.
