Heres the 2 story version. Carport to the side along with the clothes washer and dryer. Stairs up to the entrance of the living part of it. Kitchen, bathroom, tv, dining room and bed will fit in the top storey. Fish room as before down stairs. Cover up the stairs with a small/medium patio just out side the front door. 3 large windows up satirs, 3 small down stairs.
I think you need more windows on the backside of your living quarters. The back wall of your new house looks too blah.. and I think you own a jeep grand cherokee! LOL
