Perhaps you could utilize a desert style landscape and/or some type of water structure? As for the side area, if you are able to build a pergola off the side of the building that may work, or a smaller gazebo may work, as well. Possible photo ideas below.

An iron style gazebo could be planned for the center of your garden, with plantings, rocks, bird bath, pathways and stones for mulch so there is no grass could be as an option in your planning. If you are able to start with the gazebo first, then you can slowly build the garden and landscape, adding a little every year. At least you would get your seating area right away to sit and ponder what will come next, or to just enjoy being outside with a glass of wine. A fast growing flowering vine that spreads, suitable for your area could be your first planting. Scroll over picture to enlarge.
