Set on a beautiful corner lot along one of Onion Creek’s signature streets, this inviting home is full of personality, color, and thoughtful updates. It has the kind of welcoming feel where friends know to come to the back door, with a detached garage connected by a breezeway and outdoor spaces that feel both established and lovingly tended. The kitchen features a large island, stainless steel appliances, double oven, gas four-burner cooktop, custom cabinets, breakfast bar, breakfast area, and a garden window with views of the landscaped yard. The remodeled primary bathroom includes double vanities, a walk-in shower, bathtub, and walk-in closet, while the secondary bathroom has also been remodeled. Recent updates include HVAC and both bathrooms in 2023, water heater in 2022, dishwasher in 2025, plus a roof, sod, and sprinkler updates completed in 2026. The landscaping is a true highlight, with native and adapted plantings, a vegetable garden, a fountain outside the kitchen window, and mature trees that include Monterey oak, Montezuma cypress, Burr oak, Shumard oak, and a fig tree that delivers an abundance of fruit in late summer. Inside, the home offers an easy, comfortable flow with bamboo and concrete floors, double-hung windows, custom built-in bookcases, and a cozy gas fireplace in the family room. Distinctive, cheerful, and beautifully situated, this Onion Creek home blends mature landscaping, practical updates, and everyday livability in a setting that feels anything but cookie-cutter.
