Acid-stained Concrete Patio -- Looks like copper! Click the pic for a brief how-to video on doing this technique. I'd love to do this, although I wonder if the acid stain is bad for those plants around the patio.
This DIY built-in patio bench has storage space for pillows, propane tanks and other outdoor items. It even includes flower planters at both ends. Add an awning over it and it is a perfect outdoor social area.
