Impossible to date using available OS maps to any greater certainty than within the period 1949 - 1977 this part of the Birley estate is in a later style that the semi detached housing in polygon HSY 1651 to the immediate west. In this area the housing is of system built units similar to the 'Vic Hallam houses built elsewhere in the city in the early 1970s. This area of land was previously characterised by the sinuous subdivision of a larger enclosure unit (possibly a former common field north of Birley). The morphology of this enclosure pattern is clear on the 1892 OS six inch mapping and on Sanderson's map of 1835. Estate continues to the other side of Birley Moor Road. No legibility of earlier landscapes.
