Nearly 4,900 square feet of beautifully curated living space unfolds with dramatic volume, sophisticated finishes, and an effortless indoor-outdoor flow that defines luxury living in the hills. Newer hardwood flooring carries throughout the home, enhancing the soaring ceilings and sundrenched interiors. The formal living room is a true showpiece framed by towering windows, bathed in natural light, and anchored by an elegant fireplace that sets the tone for both grand entertaining and intimate evenings. It flows seamlessly into the spacious family room, where another impressive fireplace, soaring ceiling, and stepdown wet bar create an exceptional environment for hosting. The expansive primary suite serves as a private sanctuary, complete with its own fireplace, a serene viewing balcony capturing sweeping mountain and city vistas, and a spa inspired bath featuring dual water closets and a bidet. Just steps away, a loft style office/den with custom built-ins provides an elevated workspace, while a second en suite currently serving as an office/library adds versatility for today's lifestyle. The main level hosts a welcoming guest suite, and beyond the laundry room and garage entry, a discreet staircase leads to a secluded en suite ideal for visitors seeking privacy or multigenerational living. The oversized 3car garage is outfitted with built-in cabinetry, offering abundant storage and convenience. Outdoors, a tranquil rear yard with a stylish pool invites relaxation amid nature. Walking trails are moments away, as is the Mountaingate Country Club renowned for its picturesque golf course, tennis courts, dining, and nearby clubhouse with pool and lounge amenities. This exceptional community delivers a serene, resort like lifestyle with the security and elegance discerning buyers expect.

Brentwood, located between Santa Monica and Bel Air, is a residential and commercial Los Angeles neighborhood with leafy streets and hillside views. San Vicente Boulevard sets the tone, with espresso bars, produce stands, and polished boutiques clustered around the Brentwood Country Mart. Architectural character ranges from mid-century ranch homes to contemporary builds tucked behind mature hedges. The Getty Center crowns the nearby ridge with galleries and gardens that shape the area’s cultural gravity. Brentwood Country Mart and the Skirball Cultural Center act as local pillars for shopping, dining, and exhibitions. Barrington Recreation Center and the wide sidewalks along San Vicente support an outdoors-forward daily rhythm.
