We ended up having to rip up the third level to add the roof above the middle level and weather proof it.
Back to the middle level....
The screened in porch is divided up into three areas. The TV couch area, Dining area and then the middle which we aren't really doing much with yet. Originally I bought two chaise lounge chairs. I envisioned us reading a book or having coffee looking out at the water on them. One arrived and we found out the other one was backordered for so long that we got our money back. So for now we have a kids table and are leaving it empty.
The dining area is used the most I would say. We constantly eat outside. I have had several girls nights, book clubs, cookouts and most recently the kids birthday party here. We have a large table leaf and 4 extra chairs so we can easily seat 10 here.
