The building was demolished in 1970 (good riddance) and replaced by an office block called Station House, that housed The Institution of Electrical Engineers. (The IEE).
I worked at the IEE around 1977, and recall tapping away on what must have been one of the first electric Olympia typewriters. Goodness only knows what I would have done without my book of tippex paper. I think I got through about ten packs a week. How did we ever cope before computers? Although we did have them back then, it's just the CPUs were the size of mountains. I remember those days with great affection, although I left long before the offices closed and the IEE moved to Stevenage. The building was later demolished and an Audi garage is now where the two buildings once stood.***
