My employers have rented the office next to ours. As the annex is meant to contain senior management and regional services, while engineering grunts are in the main office, you could have said that, well maybe having two different offices coincidentally on the same floor would be acceptable.
Us being engineers, wanted to created a direct route between the two offices without mixing with the riffraff in the corridors, so our solution has been recorded for posterity on video
