Set on a quiet cul-de-sac in the sought-after community of Eastborough, this architecturally significant mid-century modern residence offers exceptional space, preserved design, and exciting future potential. Built in 1959 and meticulously maintained by the same family for more than five decades, the home features six bedrooms, five bathrooms, and over 5,000 square feet of finished living space. A circular drive, covered entrance, and durable DaVinci roof create an impressive arrival. Inside, the stone-walled foyer with slate flooring and a vaulted ceiling opens to spacious formal and informal living areas. The dramatic family room features exposed beams, rich wood details, a statement stone fireplace, and expansive glass doors connecting the interior to a private courtyard. Originally designed to accommodate a pool, the courtyard remains well suited for that vision and includes a covered patio for shaded outdoor living. A former bathhouse has been converted into a private office with custom granite tile counters. The authentic mid-century kitchen combines distinctive style with thoughtful function, featuring terrazzo flooring, custom cabinetry, built-in storage, a vented indoor grill, warming drawer, dedicated coffee bar, and both gas and electric cooking options. A domed dining area surrounded by floor-to-ceiling windows provides panoramic courtyard views. The spacious primary suite includes built-in shelving, courtyard access, dual vanities, a separate powder area, and a walk-in closet with built-in organization. A private accessory dwelling unit completed in 2020 adds flexibility with its own entrance, full kitchen, laundry, living area, bedroom, and bathroom. The finished basement was extensively updated in 2022 and offers luxury vinyl flooring, updated lighting, a wet bar, full bathroom, office, hobby area, and additional flexible living space. Eastborough's winding streets, scenic lakes, walking paths, playgrounds, and gathering pavilions complete this rare opportunity to own and thoughtfully evolve a well-preserved piece of architectural history.
