Overview

Perched atop the sought-after hills of North County’s Twin Oaks Valley Farms, this exquisite split-level ranch-style estate offers an unparalleled blend of natural beauty, privacy, and elegant country living. Set behind gates on a serene 2.99-acre lot, this beautifully designed residence features an open-concept floor plan, soaring vaulted ceilings, and breathtaking panoramic views with unforgettable sunsets. Located at the end of a private cul-de-sac, the property exudes peace and tranquility amidst a backdrop of pristine nature. The main level welcomes you with a spacious, open-concept living, dining, and kitchen area that seamlessly extends to a full-length, covered balcony—perfect for entertaining or simply soaking in the stunning vistas. The kitchen is a true chef’s delight, complete with an expansive granite island, sleek granite countertops, maple cabinetry, and stainless-steel appliances.

Awaken to the soothing sound of a cascading waterfall just beyond your balcony and the peaceful glow of sunrise over the hills. Upstairs, you’ll find two generously sized bedrooms, each with sliding glass doors leading to a shared, covered balcony that invites nature in. A full bathroom with a soaking tub and an open loft area with built-in office space complete the upper level, offering functionality with style.
