Set above the fog line on Howell Mountain, this single-level residence sits on a quiet corner lot within Angwin's established Sunset Drive neighborhood. At approximately 1,500' of elevation within the Howell Mountain AVA, this property offers a distinct mountain setting just minutes to St. Helena. The grounds span just over half an acre of level, usable land, rare for the area, with mature trees, expansive lawn, trellised seating area, and pergola. French doors from the dining area open directly to the rear grounds for easy indoor-outdoor living. The home measures approximately 2,454 square feet across a single level with no interior stairs. The living room is anchored by a wood-burning fireplace with stacked stone surround. The kitchen includes granite countertops, center island, gas cooktop, built-in oven, and views to the rear yard. The primary suite features a walk-in closet, sitting area, and direct outdoor access. The en suite bath includes double sinks, soaking tub, and double-headed shower. A sunroom off the suite offers flexible space for an office, retreat, or convenient nursery. Two additional bedrooms, one full bath, and a powder room complete the main residence, along with ground-floor laundry. A detached two-car garage with covered breezeway and additional off-street parking provides convenience for guests. This is an uncommon Howell Mountain setting defined by level ground, privacy, and proximity to St. Helena.
