This Gilbert, AZ backyard is built around a multi-tier rock waterfall that rises out of the deck and spills into a freeform pool below. A grotto passage runs behind the falls, boulder accents break up the waterline, and travertine decking wraps the entire shape, allowing you to access the slide from multiple angles. Landscape and underwater lighting carry the space well past sunset, and a full sport court off the side keeps the backyard working for the whole family.
