About this home

The Sycamore is a gated, heritage landmark estate above Lake Washington in Denny Blaine—designed by famed architect Carl F. Gould and reimagined by Jean Jongeward—offering 11,530 sq ft on 24,000 sq ft of manicured grounds with Cascade views. The Georgian-inspired residence delivers museum-level scale and presentation, with a formal living room framed by lake-and-mountain vistas, a globally influenced dining room, and a private library with floor-to-ceiling shelving and a spiral stair to the primary suite. Two chef’s kitchens support everyday living and major entertainment, including a Viking range, double ovens, double Miele dishwashers, a Wood Stone pizza oven, espresso station, wet bar, and expansive catering pantries. A 16-foot reception hall hosts 120 for receptions or 75 seated, while a heated loggia with radiant floors and automated privacy screens opens to terraces designed for garden parties of 300. The primary suite features sweeping views, a custom dressing room, and spa-style rain shower; additional bedrooms include ensuite baths and private terraces. The lower level adds a gym, media room, office, cold plunge, and elevator access. A temperature-controlled wine sanctuary holds ~2,500 bottles behind doors salvaged from The Olympic Hotel. Modern systems include Sonos, solar blinds, smart climate control, and comprehensive security. Minutes to Seattle Tennis Club, Broadmoor Golf Club, Bush School, Epiphany School, Denny Blaine Beach, Downtown, and Capitol Hill.
