Property Description

A private, cul-de-sac road leads to the highest point in Sewickley Heights, where “Hillside,” a William Boyd, Sr. design, feels timeless and enduring. On 11 acres of level ground, the estate reveals a tennis court woven into the landscape, while a sweeping vista is anchored by a lily pond and Italianate pool pavilion, lending both history and character. A shaded northern terrace invites long summer evenings, while the infinity pool with its kitchen, covered loggia, and outdoor fireplace creates a private retreat. The experience is defined by privacy, dramatic views, and a natural flow between home and landscape. Inside, ceilings rise 9.5 feet. From the grand entry, the main rooms extend with a rhythm designed for everyday living and entertaining. The music room, with hand-carved paneling from an English castle, embodies timeless craftsmanship and history. Upstairs, the expansive primary suite is joined by 4 additional suites, while a main-level guest suite includes its own living room.
