Description
Tucked behind gates on two private acres in Villanova, Au Vallon reveals itself slowly, like a secret estate in the French countryside. The 150-year-old carriage house, whose name translates to “In the Valley,†has been expanded and reimagined with a sense of restraint and reverence. Its original stone walls and hand-hewn beams remain the anchor, while light-filled glass courtyards, sweeping terraces, and finely detailed additions create a home that feels both historic and current. The present owners have undertaken a thoughtful transformation, guided by the principle that every improvement should be worthy of the home’s origins. Their work—ranging from a newly built pool house with outdoor fireplace to a three-car garage fitted with sculptural hydraulic doors—was carried out with the same level of craftsmanship that defined the original construction. The result is an estate where modern comforts are seamlessly integrated into the existing architecture, and where new layers of design feel sympathetic rather than imposed. Inside, the rooms unfold with a natural rhythm. The formal living room, with its built-in shelving, elegant fireplace, and French windows opening to the gardens, sets a tone of understated grandeur. Beyond a hidden bookcase door lies the dining room, where a carved mantel and French doors connect the space to the slate terrace and Linden allée. The family room, crowned by vaulted beams and a stone fireplace, is paired with a country kitchen of true scale: granite countertops, dual Sub-Zeros, a Wolf range, two dishwashers, heated floors, and a walk-in pantry designed to support both intimate meals and large gatherings. The private quarters are no less compelling. Each of the five bedrooms is en suite; several include fireplaces, balconies, or terraces overlooking the landscape. The primary suite, a study in proportion and light, offers beamed ceilings, a Juliet balcony with views of the pool, and a bath conceived as a retreat—freestanding tub before the fire, glass-walled shower, cedar sauna, and dual vanities discreetly divided for privacy. A wood-paneled bedroom with Mercer-tiled bath speaks to the home’s history, while the lower level extends the living experience with a guest suite, second sauna, gym, and direct access to the pool. Outdoors, the gardens are composed with an eye toward both structure and romance. Specimen plantings dot the grounds, while clipped Linden trees form a shaded dining canopy reminiscent of Provence. Slate patios, balconies, and roof decks create multiple vantage points to experience the property. The pool, recently restored, is a focal point, animated by a sculptural fountain and complemented by the pool house. At Au Vallon, the past has not been preserved behind glass but rather allowed to evolve—its early 19th-century bones guiding a vision of 21st-century living. The estate stands as an architectural dialogue across centuries, offering privacy, beauty, and a sense of permanence that is increasingly rare.

Climate and Weather
The Temperature chart displays average high and low values for January and July, and is designed to provide an indication of both seasonal and daily temperature variability. The Weather Risk Index indicates the calculated risk of each type of weather event occurring in the future. This risk is based on historical localized storm events and weather patterns. The national average for each type of weather event equals a score of 100, so a score of 200 would represent twice the risk as the national average, and a score of 50 would represent half the risk of the national average.
