I see an office one time with oddly long hallways 3 times the height and width one is used to. It had a marble floor that echoed loudly and ended in a Kremlin sized door with a single employee behind it. When I asked why it was that way they explained it was to force the visitor/coworker to repeatedly reconsider if his thing was really worth disruping that person with. To the question if that realy worked the answer was a description of the previous office where coworkers would fly in and out out of convenience. They would stick their head around the corner for 5 word sentences. Apparently productivity went though the roof in the new building.
