The square area of level 1 is: 540 feet by 720 feet = 388,800 square feet. Thats the size of outermost wall ( north-south) to outermost wall ( east-west) of the level. Its one of the smaller levels.
The entrance to Dwarf Home is on the right side of map 1A0.
Unless I specifically state otherwise in the room descriptions, the corridors on level one are 10 feet high.
