Can you post a picture? It would help. Thanks!

I'd love to but we are building--it's dirt now :). Basically an enclosed rectangle with a gate leading in and the front door opposite. Walls on either side, one witha door leading into a casita...I know that is difficult to visualize but it's all I have right now. Thanks

If you aren't planning to use it as an outdoor hang out space, all you need is the illusion of comfort. So a bench or pair of chairs and some potted plants. The floor can be vegetation with a path, or all covered in stone. Something hanging on one wall as outdoor art would be unexpected.
