50 Liverpool Street was the target of London’s first attack in WWI and was saved from demolition in the now famous 1979 conservation campaign run by Sirs John Betjeman and Spike Milligan. Design wise, think copper, steel mesh, stained timber and paneling - a good mix of classic and contemporary. Arched windows look into Liverpool Street Station itself and yes it's very easy to locate offices, a drop-in lounge, meeting rooms, event space and a prime virtual address.
