This is a cool idea for an outdoor patio, porch, or deck. You can roll them down for privacy or when the sun is shining right in. It would look great if they were all closed at night and there was seating and soft lighting. - gazebo too
This outdoor fireplace and patio would fit prefectly under a deck. The use of tile instead of poured concrete gives the feeling that this is not simple a patio fitted under the main deck but rather a bonifide outdoor room, with a fireplace.
