8357 E ARROYO SECO Road Live in one home and host in another. This Scottsdale estate in the private Sand Flower community pairs a beautifully updated 6-bedroom main residence with attached guest quarters that have their own full kitchen, bedroom, bath, laundry, TV room, and private entrance, so guests, extended family, or a home office get real independence without giving up a square foot of your own space. Set on a quiet cul-de-sac and a rare .83-acre lot backing to a private wash, this 5, 237-square-foot Spanish Mediterranean estate was extensively updated to a true luxury standard. A gated front courtyard with custom arched wrought iron and a serene koi pond opens to tumbled travertine flooring and a matching custom iron front door. The gourmet chef's kitchen is the heart of the home: granite counters, a gigantic center island, an abundance of custom cabinetry, a Wolf range, paneled Viking refrigerator and freezer, a deep prep sink, and dual paneled Bosch dishwashers. The oversized primary suite delivers a spa bath with dual-zone heated floors, two water closets plus bidet, dual walk-in closets, a floor-to-ceiling travertine glass shower, and a jetted soaking tub. Gather in the family room by the limestone fireplace at a custom bar with 700-bottle wine storage, a beverage fridge, and an ice maker. A separate, complete temperature-controlled wine room adds even more space for a serious collection. Step out to a resort-style backyard built for Arizona living: heated Pebble Tec pool and spa, wood-burning fireplace, built-in gas BBQ, and a rooftop observation deck with sweeping valley views. The backyard is fully enclosed by an extended-height block wall for added privacy. Behind the finishes, this home is built to save you money for years: an owned solar system, multiple EV hookups, and a temperature-controlled 4-car garage ready for a collector car or workshop. Additional upgrades are detailed in the documents tab. An updated Scottsdale luxury estate with true attached guest quarters, resort backyard, and owned solar, all on nearly an acre in Sand Flower.
