The building had a substantial "refacing" of the glazed front A4 elevation, including much more rigorous double glazing. Phone number
01-759-6522 I recall (which appears thus to have been circulating uselessly in my brain these last 35 years ...).
Worked in BOAC purchasing department for a while 1970, we moved from TBA into temporary accommodation at Heathrow House before the final move to the offices top of TBC. Now that provided fantastic views for the approach for 28R. Including a birds eye view of the 707 engine fire whilst performing engine runs.
