Don't let CSG subtract touch patches, bad things can happen. To make an section of corridor follow a 90 degree arc, first make two bevels for the inner and outer walls of the arc. Then make a brush into a 3x3 simple patch mesh , press V, and move the innermost and outermost vertices to coincide with the inner and outer bevels, respectively. The middle row of vertices goes in the intermediate positions between the two walls. That will be your floor, duplicate it for the ceiling.
