Thank you for your question. Unfortunately there aren't any more photos. This has concrete block walls with a deck above, supported by joists run (in this picture left to right), which makes for more outdoor living space.

What did you utilize for deck flooring and how did you handle/treat rain run off?

This is an exposed concrete decking with rubber membrane and 5/4 cedar decking. For rain runoff, the roof has a gradual pitch, which allows everything to run off. Hope you find this helpful.
