Welcome to one of New England's most architecturally significant and captivating properties, tucked away on 5.5 completely private, wooded acres in Cornwall Bridge, Connecticut. This iconic monolithic foam-dome residence breaks free from traditional design, offering a futuristic, sanctuary that blends seamlessly into its natural surroundings while providing exceptional structural strength and thermal performance. Inside, the sculpted, sun-drenched interior features continuous flowing lines, sweeping curves, cave-style built-ins, geometric window frames, multi-level lofts, peaceful bedroom suites, expansive living areas, and a spacious attached garage. The property offers 5 bedrooms, 41/2 bathrooms, a welcoming living room centered around a fireplace, and flexible spaces designed for privacy, comfort, and relaxation. The main residence is complemented by a separate guest unit, which is currently rented for $1,900 per month, offering an attractive income opportunity for the next owner. The crown jewel of this architectural marvel is its self-contained wellness wing, featuring a 40-foot heated indoor lap pool, integrated custom hot tub, dedicated sauna, and cold plunge pool-an exceptionally rare amenity in the heart of Litchfield County. A spectacular solarium with an adjoining stone patio provides a bright and inviting setting for entertaining, unwinding, or enjoying the peaceful countryside.
