This housing replaced late 19th century high density terraces in the late 20th century (between 1967 and 1985). Fragmentary legibility of this phase survives in odd numbers 57 - 65 'Fir Vale' and 64, 66 and 68 'Whinney Hill' all of which escaped demolition. The northern and southern boundaries of this polygon preserve the lines of former strip enclosure boundaries.
