Alan you've jogged my memory there. I worked at the DHSS offices on Soho Road for a short while in about 1974. I was there about 6 months I think. The offices were modern, low level (2 storey). There was a garage/shop at one end at ground level. It was almost opposite the Labour Exchange building.
By that time Soho Road was a fairly risky place to hang out. Us DHSS staff were warned not to go out alone along the road but to always go with someone else. Such a great pity as it's clear from old photos what a lovely neighbourhood it had once been. Consequently I never really got to know Soho Road despite having worked there. It was a matter of off the bus, into the office, then back on the bus home. No hanging around. Viv.
