Welcome to this exceptional new construction estate, privately set on over one-third of an acre in the heart of Westbury (Salisbury area). Now completed and ready for its new owners, this five-bedroom, six-bath home was built entirely from the ground up on a property where no prior home existed. From the systems and infrastructure to the designer-selected finishes, every detail is brand new.
Meticulously crafted by STM Complete Contracting Inc. and curated in collaboration with an interior designer, the home blends thoughtful design, comfort, and functionality. A private driveway offers ample parking for guests.
Step inside the vaulted foyer, where light white oak floors and designer lighting set the tone for the open-concept main level. The kitchen features dual-tone custom cabinetry in white oak and soft cream, Taj Mahal stone countertops and backsplash, an oversized island, a statement plaster range hood, and Thermador appliances. Designed for everyday living and entertaining, the space includes two dishwashers and two refrigerators: one in the kitchen and a second in the spacious walk-in pantry.
The living room features custom built-ins, a gas fireplace, and a custom bar with a Taj Mahal stone waterfall counter and wine refrigerator. Large sliding glass doors open to the patio and backyard, creating a seamless connection between indoor and outdoor living. A formal dining room with coffered ceilings, a versatile flex room with access to a full bathroom, and a mudroom off the attached two-car garage complete the main level.
Upstairs, four private bedroom suites each have their own bathroom. The primary suite features a vaulted ceiling accented in light oak, custom fluted wall panels, and designer pendant lighting. The spa-inspired primary bathroom offers organic neutral porcelain tile, an alabaster chandelier, marble sconces, and electric radiant-heated floors. A dedicated second-floor laundry room includes two stacked washer and dryer sets.
The fully finished basement offers eight-foot ceilings, egress windows, a full bathroom, and a separate entrance with six-foot sliding glass doors leading to the backyard. The generous space provides possibilities for additional living and entertaining.
Outside, privacy landscaping surrounds the property, while the expansive backyard offers a blank canvas to create your own outdoor retreat, with ample room for a pool and entertaining areas.
Additional features include a high-efficiency Lochinvar NKC combination boiler with on-demand hot water, two heating zones, two cooling zones, smart thermostats, smart irrigation system and smart exterior lighting. This completed home offers a rare opportunity to enjoy new construction, designer finishes, privacy, and generous living space in an exclusive location of Westbury.
