Welcome to 125 Hampstead Mews NW, a truly exceptional custom estate home located on one of The Hamptons' most prestigious streets. Offering over 4,730 sq. ft. of developed living space, this meticulously crafted residence blends timeless luxury, thoughtful design, and outstanding craftsmanship. From the moment you enter, the attention to detail is unmistakable. Soaring 10-foot ceilings on the main floor and basement, 9-foot ceilings upstairs, custom floor-to-ceiling windows, designer wainscotting, extensive millwork, and carefully curated finishes create a home that feels both grand and inviting. Natural light floods every room, highlighting the exceptional quality found throughout. At the heart of the home is a chef-inspired kitchen featuring a Sub-Zero refrigerator, Wolf appliances, built-in Miele coffee system, filtered water, premium cabinetry, and an oversized island designed for both everyday living and entertaining. The adjacent living and dining areas are anchored by a stunning custom stone fireplace, while dual oversized sliding glass doors seamlessly connect indoor and outdoor living. Designed to prioritize luxury and comfort, the upper level features two spacious secondary bedrooms, each with their own private ensuite, a large bonus room, and one of the most impressive primary retreats available in Calgary today. Encompassing approximately 723 sq. ft. including the spa-inspired ensuite and walk-in closet, the primary suite offers a freestanding soaker tub, steam shower with integrated lighting, heated floors, and an atmosphere more reminiscent of a luxury resort than a residence. The professionally developed basement offers expansive recreation space, in-floor heating, wet bar area, and rough-in for a future golf simulator. Whether entertaining guests, creating the ultimate sports lounge, or building a private retreat, the possibilities are endless. Built to an exceptional standard, the home features dual furnaces, dual air conditioning systems, dual HRV units, dual boilers, advanced comfort zoning, snow melt, hot water recirculation, water softening, filtered water systems, a 120-gallon hot water tank, EV charging rough-in, and future solar readiness. The oversized heated garage is equally impressive with 14-foot ceilings, epoxy floors, custom cedar shelving, in-floor heating, hydronic unit heater, and a 60-amp disconnect for a future swim spa. Outside, enjoy professional landscaping, irrigation servicing both gardens and the heated greenhouse, exterior architectural lighting, security cameras, and multiple outdoor living spaces. A rare opportunity to own one of The Hamptons' most thoughtfully designed luxury homes. (id:60457)
