A sweeping 180-degree panorama stretches across the water to Seattle and Bellevue skylines, with views framing nearly every principal room. Exquisite finishes balance impressive scale with genuine warmth. A spectacular entertaining kitchen with a hidden scullery anchors the home for everyday living or large-scale events. The main-floor primary suite offers a private sanctuary with direct access to the outdoor Jacuzzi, while en suite bedrooms provide comfort and flexibility. A dedicated wine cellar, private sauna, library, expansive rec/media room, and dual offices balance the demands of daily life with the art of entertaining. A full apartment with elevator access provides a retreat for guests or multigenerational living. Outside, meticulously landscaped grounds unfold with layered plantings, and expansive lawn extending toward the water. A covered, heated outdoor room with a kitchen invites year-round enjoyment of the waterfront setting. A private dock with yacht moorage of approximately 75 feet, also accommodates a float plane, ski boat, two jet skis. The estate offers remarkable convenience, just minutes to the I-90 corridor. An extraordinary convergence of land, water, architecture, and view, this is an exceptional offering at one of Mercer Island’s most coveted waterfront addresses.
