Panoramic rolling-hill, sunrise and sunset views frame the setting, while custom entry, side gates and professionally designed landscaping with natural boulders, a decorative dry creek bed and stacked-stone retaining walls create a distinctive sense of arrival. Generous windows throughout the main residence draw in abundant natural light and carry views of the grounds into the home.

The kitchen boasts an oversized half-moon island with additional seating, new stainless steel appliances and flows into the family room, casual dining area and butler's pantry or coffee station. Three additional bedrooms each featuring full ensuite bathrooms and large windows overlooking the natural surroundings. The primary suite occupies its own wing with a retreat and access to a secluded outdoor sitting area surrounded by lush landscaping. Its spacious bath features a jetted tub, oversized walk-in shower with dual shower heads, two separate sink areas including a vanity, dual private commode rooms and a large pass-through walk-in closet. A dedicated office and two separate attached two-car garages provide four-car garage capacity. Recent improvements include fresh interior paint, new hardware, fixtures and new flooring in select areas. Exterior paint with a fire-resistant coating was completed on both structures in 2025. The grounds unfold from a Pebble Tec pool with waterfall, infinity edge and wading pool to a built-in gas BBQ and surrounding turf. Beyond, mature trees and winding pathways create a peaceful, woodland-like setting. Fruit trees, irrigation, RV access, a potting shed and additional storage structures enhance the property's versatility and equestrian potential.
