First depicted on the 1984 1:10,000 mapping as colonized by small sheds which are most probably light industrial units. This area retains the grid pattern of streets first laid out in the later 19th century during the heyday of the industrial Don Valley (hence fragmentary legibility is recorded for this area). Victorian houses appear to have been cleared in this area as the economic decline of the Don Valley gathered pace through the 1970s and early 1980s. Liddament (in Hey et al 1997, 99) quotes the following statistic, "Between 1975 and 1988 the Valley suffered a reduction in employment from 40,000 to 13,000 jobs. By 1988 fewer than 300 residents remained and 40 % of all the available land was vacant, derelict or underused." The area covered by this polygon was formerly a mixture of high density terraces and back to back 'courts'. These in turn had been built within the area shown on the 1851 OS 6 inch mapping as garden plots behind settlement along the main pre-existing road pattern. This area is likely to have been associated with burgage plots behind the medieval settlement of Attercliffe.
