Oh Man!!! This is sooo cool! it doesn't even kind of go with the style of my future pool, but I totally want it! maybe you can take it in and out of the pool as you please! Or maybe I'll just have it built in in the correct colors and style to match the pool but still be totally awesome because I'm in love with this idea!
Summer shade. Could probably find the wire and curtains at Ikea. Attach one side to the house and the other side to poles, slide the curtains across for shade and slide them back and secure during a storm.
