Our client had a deck off the back of her house and wanted a three season room. The room is 14x14 with a vaulted ceiling, knotty pine interior and vinyl sided exterior. The floor is a tongue and groove composite decking because she liked the look of it so 1/2" pressure treated plywood was installed under the new floor joists. There are eleven 3'x5' slider window and 4 trapezoid windows in the gable end
