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 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.
