Brand-new, never lived-in estate located in the prestigious guard-gated community of Westcliffe at Porter Ranch. Situated on a premier 10,409 sq ft lot and offering approximately 5,200 sq ft of refined living space, this highly upgraded residence stands apart from typical resales. A grand entry framed by mature palm trees creates an elegant Southern California arrival. The open-concept floor plan features soaring ceilings, wide-plank flooring, expansive glass, a dramatic floating staircase, and a striking double-height glass wall. The chef’s kitchen is appointed with quartz countertops, an oversized island, premium stainless steel appliances, soft-close cabinetry, and a built-in wine refrigerator. The family room opens seamlessly to the backyard through multi-panel sliding doors. The newly completed backyard showcases a custom saltwater linear pool with elevated spa, professional landscaping, and mountain views — delivering a true resort-style setting. Additional upgrades include integrated surround sound and enhanced security system. Located within a secure guard-gated enclave, close to The Vineyards shopping center, reputable private schools, award-winning public schools, and convenient access to the 118 & 405 freeways.
Porter Ranch, located between Chatsworth and Granada Hills, is a hillside and master-planned Los Angeles neighborhood with wide canyon views and trail-lined open space. The scene concentrates around the Porter Ranch Drive and Rinaldi Street corridor, where patios, boutiques, and a steady café-and-errands rhythm set the tone. The Vineyards at Porter Ranch anchors daily life with an open-air plaza feel, while the Porter Valley Country Club and the nearby Getty Center’s Sepulveda Pass presence add cultural and recreational gravity. Streets climb into newer stucco-and-tile homes, with pockets of larger lots near the foothills. Aliso Canyon Park and the Santa Susana Mountains frame the edges with big-sky hiking. The pace reads polished and outdoors-forward, with commutes flowing toward the 118 and 405.
