Sonoran Desert Home, Scottsdale, Arizona
The Sonoran desert and its accompanying mountain views are merely the backdrop for entertaining at a Frank Lloyd Wright-style home on more than 16 walled acres in North Scottsdale, Arizona. The backyard perks include a 300-foot zip line and a chugging train custom built to resemble the Santa Fe railway for kids. Guests can also swing Tarzan-style from a rope tied to a tree into the million-dollar resort-style infinity pool, with waterfalls, grotto, slide and a spa for 10. Patrick Kirby, a senior marketing consultant at Grand Estates Auction Company, recently sold the home at auction for $4.6 million.
