A spectacular blend of a significant nearly new home designed by David Mann, major internationally-acclaimed architect and principal of MR Architecture+Decor, combined with a fully-restored c. 1872 Antique Colonial - all presiding over 5.6+/- acres of pastoral property, positioned to capture vistas across the grounds of the Fairfield County Hunt Club. This much-admired custom residence offers beauty and flexibility in a prized, central location. The original section now serves as an attached, fully-equipped guest house ideal for multi-generational living or a home office. Authentic to the setting, the new section is defined by custom millwork and windows, gracious scale and the modern amenities that enhance today's lifestyle incl energy features/partial geothermal heating. The front-to-back foyer is introduced by a tall custom doorway surrounded with leaded glass and has views extending across the land; sunlight streams-in through glorious windows soaring to the 2nd level. The front-to-back living room has 1 of 6 fireplaces. The formal dining room with fireplace has French doors to the mahogany and stone balcony - as do many rooms. Stunning gourmet eat-in-kitchen adjoins the family room. The master suite has dual dressing rooms and marble bath with full slabs. Set on one of the largest single parcels of residential property in Westport, this home is replete with every amenity. A glorious pool, pool house, garden, expansive mahogany porches/balconies, stone patios and outdoor fireplace are only the beginning of the myriad features that will enchant you.
