1 Kings 6:3-6

3The entry room at the front of the Temple was 30 feet wide, running across the entire width of the Temple. It projected outward 15 feet from the front of the Temple.

4Solomon also made narrow recessed windows throughout the Temple.

5He built a complex of rooms against the outer walls of the Temple, all the way around the sides and rear of the building.

6The 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.
