An impeccably maintained single-owner residence offering generous square footage, thoughtful design, and enduring quality throughout—all in a practical layout. Rich solid ash hardwood floors, custom walnut woodwork, soaring ceilings, and statement chandeliers establish a standard of craftsmanship that carries through every room. Expansive, light-filled living areas open seamlessly to a tigerwood deck appointed for refined entertaining, with sweeping territorial views and exceptional privacy. The professional-grade kitchen features Viking, SubZero, and Miele appliances, slab granite countertops, a dedicated pantry, and abundant storage. A handsome study with custom walnut boxed ceiling and bookcases provides an ideal workspace or private retreat. The primary suite offers a serene sanctuary complete with a fireplace, spacious walk-in closet with an original Art Nouveau built-in armoire, and a five-piece bath. Three additional upper-level bedrooms—one with a large bonus room and separate entrance—along with a main-level guest suite or first floor primary provide versatile accommodations well suited to multigenerational living or live-in staff. The lower level is designed for both leisure and hospitality, anchored by a fireside recreation room with a zinc wet bar and wine cellar, complemented by a dedicated home theater. Additional appointments include zoned HVAC, integrated audio, backup generator, solar thermal water heating with recirculation, and an oversized three-car garage. Situated directly across from Pioneer Park in a quiet south-end neighborhood, the property offers convenient access to parks, recreational trails, retail, and highly regarded Mercer Island schools.
