The last of roughly five boxes in Southampton. Redbridge road and Green Park Road. 1960s Probably built due to the near by substation closure.
The first was built at Warren Avenue near the corner of warren crescent, Shirley Warren in 1939.
Other were:
Within the grounds of Queen's Park, a very large box.
Corner of Highfield Avenue and Furzedown Road.
Golf Course Road corner of Bassett Avenue
Likely all these boxes where brick.
