I built an overhead trellis for a climbing rose, with a bench, and at the top put a clothes' rod - used that to dry most clothes most of the year... back when I lived in Venice, California. If I did it again I'd use a clothesline so that I could use spring clips to hold the hangers, if there were a chance of wind (hangers twirl on a regular closet rod in the wind).
Here in Albuquerque I could do that again except my whole back patio columns and roof need rebuilding, and cost is a factor. Also, it's often windy or wintery here. But, the air is dry, so I often dry some stuff on the bathroom shower curtain rod, and the remainder in my gas dryer. I tend to take clothes out early and whap the wrinkles out and hang them up/closet immediately. No mold problem here.
