1 Kings 6:6, 10

The complex was three stories high, the bottom floor being 7-1/2 feet wide, the second floor 9 feet wide, and the top floor 10-1/2 feet wide. The rooms were connected to the walls of the Temple by beams resting on ledges built out from the wall. So the beams were not inserted into the walls themselves.

As already stated, he built a complex of rooms along the sides of the building, attached to the Temple walls by cedar timbers. Each story of the complex was 7-1/2 feet high.
