Thanks to Walk@Wessex, I get to explore the area for the first time.
Built in the 1940s by the British administration Public Works Department (PWD), the houses were homes for non-commissioned British officers and soldiers from 1948 up to the 1970s. Aside from a designated number, each block was also given a name (e.g. PEGU, QUEBEC, NAMUR, BLENHEIM, ARABIA) that corresponded to military feats of British History, dating as far back as to the 18th century.
Lovely stairways too.
