"Son, I don't know about this Modern architecture." Our first guests, enjoying the open floor plan, but understandably concerned for our comfort during Iowa's long winters. Dad supports the door frame to the laundry room while Joanna serves as tour guide for Joyce, standing at the (future) bottom of the stairs.
This is an interesting detail of the floor joists underneath the main level shower. Rot-resistant wood under the bathroom--brilliant!
