The remodeled kitchen shines with cherry cabinetry, matte granite countertops, stainless appliances, and a custom island. Retreat outdoors to a private gunite pool, hot tub, patio, and mature gardens. The primary suite offers a fireplace, skylight, and custom closets. A rare MIT-inspired drain-back solar heating system stores warmth for days, enhancing comfort and energy efficiency throughout the home. Central air conditioning and an attached two-car garage add modern convenience.Thoughtfully built with sustainability at its core, this is a one-of-a-kind private oasis.
