Nestled within nearly 36 pristine acres, this newly completed custom estate is a triumph of "quiet luxury" and environmental stewardship. Arrive through a private gated entrance to a meticulously secured property, offering absolute anonymity and thoughtful smart-home security. Built with eco-friendly, zero-VOC materials, the sun-drenched interiors feature a warm neutral palette, artisanal finishes, and a seamless flow. The primary wing serves as a private haven with a spa-like bath and private balcony. Below, a walkout lower level entertainer's dream hosts a wellness room, home office, and custom sauna. The estate grounds feature a pool, integrated spa, and an incredible 3,400 sq. ft. climate-controlled car barn outfitted with custom lighting and an indoor climbing wall. A rare fusion of architectural responsibility, advanced peace of mind, and elite private recreation. Private showings available by appointment.
