Back to the playhouse. I designed the framing for the "loft" area. Here's a shot with all the framing, which makes the loft (in white) hard to see.
Here's a shot without the roof and the west wall to make the loft easier to see. I shaped the loft floor like and L. I did this to make the loft feel a little bigger, but now I think this requires additional support columns, which will interfere with the "first floor" floor space.
