Hidden behind majestic wrought iron gates along a legendary stretch of Potomac's Millionaire's Mile is 9421 Newbridge Drive, a neoclassical estate home constructed by master builder David Niroo and crafted by world-renowned designer Haleh Niroo of Haleh Designs. Approached by an elegant crescent-shaped drive, the estate represents a bygone era of fortress-like construction, meticulous workmanship, and an intertwining unparalleled quality with state-of-the-art technology. A triple set of glass and wrought iron entry doors reveal a palatial barrel-ceilinged reception vestibule, opulently lined with inlaid marble floors and Corinthian columns. To one end, a whimsical marble bifurcated staircase, bathed in light from the arched landing window and lined with intricate wrought iron railings, graciously winds itself to the upper level. As with all Niroo mansions, the floor plan is a masterclass in blending grandiose formal rooms with intimate informal areas. Twelve-foot ceilings throughout the main level impart an ethereal flow through the voluminous spaces. The grand salon, a showstopper with its double-height ceiling, soaring Palladian window, and a triple set of French doors, evokes sensations of lavish entertaining during the Gilded Age. The living room features a roaring fireplace, coffered ceiling, and terrace access, yet manages to remain usable despite its formidable scale and luxurious appointments. The dining room features exquisite moldings, a double set of French doors, and effortless flow to facilitate gatherings. A magnificent paneled library with a fireplace and bay window overlooking the grounds offers a post-dinner retreat. The country kitchen is a chef's dream with furniture-grade inset cabinetry and commercial-grade redundant appliances. The adjacent breakfast room is inviting with its fireplace and terrace access. A comprehensive butler's pantry and mudroom accessing the four-car garage complete the main level. Sharing an upper-level landing with the grand staircase is the private elevator. Six bedrooms, including a lavish primary suite, feature comforts such as dressing rooms and designer bathrooms befitting those of the world's most sumptuous five-star hotel rooms. The fully finished lower level is amenity-rich with a large recreation room, wet bar, and private cinema. Sitting above ground and consequently flooded with natural light, the space walks out to a cozy loggia. An additional bedroom suite offers multigenerational flexibility to the highest degree. Out back, the stone terrace looks out to unbroken, verdant vistas and 2.25 acres of level, usable space. Commercial-grade systems are discreetly hidden behind the scenes to ensure peace of mind, as are luxuries such as full audiovisual capability via a video surveillance system and whole-home audio. Unrivaled in workmanship and situated in a prime Falconhurst location, 9421 Newbridge Drive is undoubtedly one of the Capital Region's great estates.
