Set on 10 breathtaking acres in Sewickley Heights, this extraordinary 1935 estate is one of the area’s most iconic properties. Thoughtfully reimagined, it blends timeless architecture with refined interiors and modern luxury. Beautifully scaled rooms feature high ceilings, exquisite millwork, and abundant natural light. Formal living spaces include an elegant library and gracious living room with limestone fireplace. A custom kitchen centers on a La Cornue Château range and opens to a light-filled breakfast and gathering room. A dramatic Great Room with vaulted ceilings and exposed beams provides a spectacular venue for entertaining. Outside, expansive stone terraces, formal gardens, a reflecting pool, greenhouse, bocce court, and resort-sized swimming pool create a private, resort-like setting. A six-car garage completes this exceptional property.
The Main House of this turn of the century Sewickley Heights estate, renovated with meticulous attention to detail, offers a six-car garage, pool, bocce court, greenhouse, and is completely enclosed by a nine-foot-high fence. One of the first three Sewickley Estates, this iconic architectural property boasts a luxurious, designer-quality interior, a Great Room that features soaring vaulted ceilings with exposed oak beams, and a Billiards room with a generous nine and a half foot-wide stone fireplace. The entire property set on more than 23 acres, also offers a newly renovated 2 bedroom Guest House; while more contemporary in feel it mimics many design details of the Main House such as Shaker siding, wood beams as well as a sun-filled kitchen with a La Cornue stove and rotisserie cook station. Just off the Guest House is a stone Artist Studio and four possible Building sites. Equestrians have plenty of space to add more pastures and refashion an unused existing riding ring.
