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.

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.
