Last week I happened to find a wooden playhouse on ebay. I bid on it and won. It is made of wooden Dutch-lap siding attached to 2X4's. It was constructed in panels so it can be easily disassembled and moved. The floor is made of 2X6 pressure treated lumber. It is about 54 inches wide and 60 inches deep. I plan to put hardware cloth on the windows for the summer. I'm not sure what I'm going to do with the door opening yet. I'd like to cut the deck off in the front even with the house and possibly raise the whole thing up off the ground a little. The windows are only large enough to accomodate 1 nest box, if I decide to go that route. Any suggestions? What are the potential problems of having pressure treated lumber for the floor, should I paint it? put vinyl flooring on it?
