'Extension' in the Bible

He built an extension all around the walls of the temple's main hall and holy place and constructed side rooms in it.

The bottom floor of the extension was seven and a half feet wide, the middle floor nine feet wide, and the third floor ten and a half feet wide. He made ledges on the temple's outer walls so the beams would not have to be inserted into the walls.

He built an extension all around the temple; it was seven and a half feet high and it was attached to the temple by cedar beams.
