A rare custom-built gated estate in Northwest Ajax, 14 Fielding Crt sits at the quiet end of an exclusive 15-home cul-de-sac, embraced by mature trees on 2.36 private acres. From the automatic gate, stone exterior and expansive unistone drive, the property makes an immediate statement: a home built for scale, privacy and a life well hosted. Inside, approx. 8,500 sq. ft. of finished living space unfolds with hardwood floors, crown moulding, formal principal rooms and a dramatic floating staircase. The great room rises to an impressive 19-ft ceiling, creating a sense of volume and occasion, while the kitchen is the natural gathering point with granite counters, floor-to-ceiling cabinetry, a large centre island and walk-out to outdoor living. The main-floor primary suite offers ease without compromise, with a fireplace, dual walk-in closets and a 6-piece ensuite with jacuzzi tub and steam shower. Upstairs, three generous bedrooms provide comfort and separation, while the loft above the heated 3-car garage adds rare flexibility: a private studio, office, lounge, games space or retreat for family and guests. The finished walk-up lower level feels like a private club, designed for evenings that move from conversation to cinema to restoration. A lounge, wet bar with draft tap, wine cellar, recreation room, 6-seat theatre with surround sound, gym, two bedrooms and full spa area with steam room, sauna, change room and shower create a complete entertainment and wellness experience. Outdoors, the estate becomes a resort of its own, with a 60-ft heated pool and waterfall, hot tub, cedar deck, fire pit, landscaped grounds and treed privacy on every side. A detached 9-car garage/workshop adds exceptional utility for collectors, hobbyists, trades, storage or equipment, complementing the attached 3-car garage and extensive parking. A legacy-level property for buyers seeking estate privacy, refined function and a lifestyle rarely offered in Durham Region.
