Modern Art Deco Revival Estate in The Country EstatesA rare architectural statement within the prestigious 24-hour guard-gated Country Estates, this Modern Art Deco Revival estate commands a private, resort-caliber setting with sweeping panoramic city-light and mountain views.Set behind a grand approach, the residence blends sculptural geometry with refined Contemporary symmetry, offering a lifestyle designed for both elevated entertaining and serene everyday living.The grounds unfold as a true private resort: a full-size tennis court, elevated pool and spa terrace curves along the landscape with sweeping views, putting green, gazebo, viewing deck, and curated gardens framed by mature fruit trees, including orange, guava, kumquat, tangerine, apple, dragonfruit, and rare Leon avocado. Every element has been thoughtfully positioned to maximize privacy and panoramic vistas.Dramatically extending from the upper level, an expansive viewing and meditation tower unfolds as a light-filled architectural aerie designed as a sanctuary above it all. Framed by sweeping panoramic vistas, the elevated pavilion offers a rare vantage point for sunrise rituals, sunset reflection, and stargazing under open skies.Inside, soaring ceilings, distinguished archways, expansive walls of glass create a luminous interplay of light and space. Floor-to-ceiling windows invite the outdoors in, while an expansive floor plan offers seven bedrooms, multiple grand-scale living areas, and a private executive office with its own entrance.The chef's kitchen is appointed w/ Sub-Zero refrigeration, professional-grade appliances, custom cabinetry, & an oversized island designed for gathering.The primary suite serves as a tranquil retreat, featuring spa-inspired amenities, a soaking tub, walk-in shower, bidet, & private lounge area. Six additional bedrooms provide generous accommodations for family and guests. Reinforced security glass & carefully selected finishes reflect a commitment to both elegance & peace of mind.Enhancing the resort experience is a detached wellness retreat, complete w/ sauna, dedicated shower suite, & private water closet, delivering spa-level amenities just steps from the pool terrace.Residents of The Country enjoy 24-hour security, clubhouse, equestrian trails, parks, playgrounds, & award-winning Walnut Valley schools.This is more than a residence, it's a legacy estate defined by architectural presence, privacy, & the highest standard of SoCal living.
