A private, cul-de-sac road leads to the highest point in Sewickley Heights, where ‘Hillside,’ a William Boyd, Sr. design, feels both timeless and enduring. The estate is surrounded by eleven acres of rare, level ground that brings a sense of calm and freedom—space for gardens, play, or quiet reflection. A sweeping vista is anchored by a lily pond and an Italianate pool pavilion, lending both history and character to the estate. From sunrise to sunset, every room is filled with natural light, creating a rhythm that shifts gracefully with the seasons.Outdoor living remains central to life at Hillside. A shaded northern terrace invites long summer evenings. Nearby, the newer infinity pool and its covered entertaining area—with kitchen, fireplace, seating, changing rooms, and bath—offers a private retreat and unencumbered glorious sunset views. The tennis court sits tucked into the landscape, and stone staircases lead from the broad terrace down toward the lily pond and gardens designed for quiet reflection. Everywhere, the experience is shaped by privacy, dramatic views, and a natural flow between the home and its landscape.Inside, the home unfolds with equal grace. From the grand entry, the main rooms flow with a natural rhythm designed for both everyday living and gracious entertaining, enhanced by ceilings that rise nearly nine and a half feet. The Music Room, with hand-carved paneling from an English castle, is a showpiece of craftsmanship and history. Its floors include a section of intricate wood grating—originally designed to carry the sound of organ music from a room below—an extraordinary reminder of the home’s past. The adjoining library, living room, and dining room continue this sense of connection, each space anchored by working gas fireplaces that lend warmth and continuity throughout. In the dining room, a broad bay window frames views of the gardens, while an inlaid marble fireplace adds refinement to gatherings both intimate and grand. The architectural heart of the house is the grand foyer, where a sweeping staircase curves upward to a luminous round window that fills the space with light. French doors at the far end open to the gardens, underscoring the home’s seamless flow between indoors and out.Modern updates complement the historic character. An expansive kitchen, complete with a butler’s pantry set within the original hexagonal water tower, is complemented by a breakfast room and a sitting room, creating a natural gathering space, especially in the afternoon light, overlooking the garden. The tower’s second level holds a guest bath. The spacious laundry room, wrapped in windows with views of the gardens, makes even routine tasks a pleasure. Upstairs, the primary suite features a walk-in closet, a spacious bath, and an office overlooking the circular drive, framed by lush gardens—an arrangement that strikes a balance between privacy and beauty. Four additional guest suites upstairs, and a main-level suite with its own living room, provide comfort and flexibility for family and guests.Hillside is more than a residence—it is a rare sanctuary, shaped by light, landscape, and legacy. Here, every detail speaks to the enduring joy of home.
