Experience unparalleled luxury living in Sereno Canyon with this extraordinary Toll Brothers estate, offered at ~$900,000 below replacement cost. Situated on a premium, boulder-framed lot, this highly upgraded home is a rare opportunity to enjoy refined elegance with breathtaking natural beauty. The streetscape features a massive paver driveway climbing through pristine natural desert to a groomed desert prelude. A limestone path leads you into the stacked stone front courtyard, where lush turf is accented by hibiscus, jasmine, lavender, and boxwood to create a serene oasis. Enter through the iron front door where the grand foyer draws your gaze to the central courtyard and the stunning backyard beyond. The expansive great room is a masterpiece of design, anchored by an oversized horizontal gas fireplace swathed in agate-inspired tile. The custom kitchen is equipped with top-tier Wolf, SubZero, and Asko appliances, complemented by a double-waterfall island wrapped in natural quartzite that continues on the counters and backsplash. For work or relaxation, the office pampers with double-door entry, views of boulder formations both in and out of the yard, and a striking soft-touch designer wall treatment. The primary suite is a sanctuary featuring the owners' private media room and an oversized bedroom, both with custom wood slat wall treatments. The opulent primary bath showcases tasteful tile and granite finishes, with back-lit floating mirrors. The guest wing offers a luxurious powder room, plus three additional bedrooms, each with its own custom bath en suite. Wine enthusiasts will appreciate the 102-bottle SubZero wine fridge paired with a custom wine-cork countertop and ample storage for stemware and libations. The five-car garage boasts epoxy flooring, extensive storage solutions, and a custom workbench with tool drawers. Step outside through custom 20' corner glass doors to discover your private paradise. The backyard features lush landscaping, a never-used grill station, and a dramatic 28' reverse negative edge waterfall cascading over iridescent glass tiles framed by stacked stone planters. The elevated spa is wrapped in matching glass tiles and spills over to the pool's baja shelf. Enjoy leisure time on the 4-hole putting green or gather around the granite-slab firepit and banco nestled into towering natural boulders. The central courtyard offers more surprises--covered and open patios share a two-way fireplace, while a lush side yard rivaling most backyards, is crowned with another custom banco with sweeping views of Tom's Thumb and the McDowell Mountains.
