About This Home
Rarely does a home offer this level of flexibility, privacy, and opportunity. Lovingly maintained by its original owner, this custom residence features an attached accessory dwelling unit (ADU), an increasingly sought-after amenity for multigenerational living, extended family, or rental income. Conveniently located on the same level as the family room, kitchen, dining area, breakfast nook, and expansive backyard deck, the ADU also enjoys garage-level access, making daily living more comfortable for extended family members or guests. Set on more than an acre adorned with picturesque trees, the property is surrounded by the preserved native beauty of California landscape. Inside, the formal living room welcomes you with a dramatic wood-beamed ceiling and charming fireplace. Just below, the formal dining room is surrounded by windows that frame the landscape and make every gathering feel connected to the outdoors. The family room, kitchen, and breakfast nook continue the experience, offering sweeping views of the trees and hills beyond, along with a deck that runs the length of the home. Five bedrooms and four bathrooms are thoughtfully arranged across the tri-level design, with balconies off all of the bedrooms providing peaceful places to enjoy the scenery. A hallway nook creates the perfect space for a small library, office, or craft room, and the home offers abundant storage throughout. Update the interior to your preference and you will have the perfect forever home. Outdoors, the natural landscape showcases Pepper, Sycamore, and Live Oak trees along with the fragrant beauty of sage, monkey flower, buckwheat, California poppies, and orange trees. Bird lovers will enjoy the many colorful hummingbirds and various birds who also call this place home. An outdoor gardening room allows you space to continue preserving this rare native land, while an additional driveway provides extra parking for gatherings. Residents of Country Estates enjoy access to a heated swimming pool, badminton courts, basketball courts, tennis courts, pickleball courts, and scenic walking trails, all within the gated community.
