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.
