All rooms should either be square or rectangle in shape.
Say you make the rooms in the shape of a circle, octagonal shape, at an angle or in the shape of a star to state a few examples. Do not set the rooms in shapes thinking that it will be unique and different from the usual layouts. You will lose your peace of mind.
