Great idea for a patio in a backyard with limited shade and space to garden. A covered patio with windowbox container garden as a creative use of backyard space and landscaping idea for vertical space.
two twin beds. A curtain hung from that cute heading would disguise your "bedroom" if you chose. A curtain would work above as well for either a bed or built in shelves and hanging space for your clothing; I really love the idea of deep, built-in beds
