Many offices will contain large numbers of rooms, so it is important that specific rooms can be easily found. Conference room signs should be attached to the door using a plain coloured placard with a business-like font. There should also be directional signs showing where the room is located if the office area is large because whilst staff may know where to go, visitors will not. In addition to this, it can be helpful to have a board showing on which floor the room can be located and this is usually placed by the stairs or a lift. It can also be useful having directions to this room displayed in the lobby.
