I'm not exactly sure what you are asking here. If it were me, I'd try to break up the concrete in some manner. Using a lot of flower-filled pots would help a lot and arranging your furniture in a conversation pit style would help. Also, consider looking for an outdoor rug to soften the environment and add color. They come in all types and last forever outdoors. You can see a lot of outdoor design ideas in our Decorating Gallery on the home decor section of bhg.com. We put over 50 photos of some of our best outdoor living locations in that Gallery.
