The finished terrace level is ideal for entertaining, offering a full kitchen with its own newly installed ice maker (2025), a large recreation area, climate-controlled wine cellar, gym, 16-seat home theater, and two additional bedrooms.
Recently painted inside and out, this home also features oak hardwoods on the main level, 12'+ ceilings on main and terrace, exquisite 5-piece crown molding, and rich architectural detail throughout. Seven gas fireplaces add warmth and ambiance across the home.
Functional upgrades include a new whole-home 30-KW generator (2023), Leaf Filter guards installed in April 2025 at key roofline sections, and all seven HVAC systems replaced within the past two to five years—ensuring comfort and peace of mind for years to come.
The outdoor living spaces are equally impressive with two large covered back porches, a screened porch with fireplace, and two separate outdoor seating areas with fire pit and grill. The beautifully landscaped and fully irrigated grounds include level sodded land, a fenced pasture, and a detached carriage house (with garage door previously used for a boat)—offering excellent potential for a hobby or small-scale horse farm.
