We put in the temporary vertical beam to support the Loft floor and the removed the stone wall in the middle story.

Clark masoned the wall on the end of the lower room to straighten it, and we set a 12 x 12 beam on it to take the joists we would add for the floor.

You can also see the opening in the wall near the center of the picture that will be a passage at the bottom of a stairway.
