A reflected ceiling plan (RCP) is a plan view of the upper part of a room, showing fixtures such as lighting, air conditioning grills, and other equipment that are located on the ceiling. It reflects both ceilings and walls, which allows the viewer to gain an accurate idea of how the wiring runs throughout the house. This kind of architecture drawing can be used to show the division between an open-plan living room and a bedroom by showcasing their respective ceiling designs or elements.
