piggie I would also love to know where the table is from. I am in DC area but would buy and ship. I just finished a house and did a copy of one of your big stone fire places with generous hearth and mantle. I LOVE IT
If the screen porch was more like an outdoor room addition, then area for large dining experience with this type of table and seating for 18, as well as normal outdoor living room with fireplace is a great combo for 2-3 season usage
