I am considering enlarging my patio. Currently 6'x 12' with plans to extend to a 12'x 25' and enclose with extensive glass for a natures view. Which is the easier for me to try to tackle, a framing with T111 or a Metal enclosure with surround windows. Windows to be constructed at about two feet fromt the ground to about six feet from seven foot ceiling to maintain a pit on the roof. I am also seeeking the most economical means.
