This beautiful home offers six bedrooms, or five with an office, with ensuite bathrooms, a gym, a wine room, and a basement. This house has thoughtful additions and upgrades beyond its original build, offering a turn key home with transitional aesthetics. A seamless, meticulous renovation has made it a calm, sophisticated retreat, with high ceilings, Karastan carpeting throughout, Wolf appliances, high-quality stairs, and a fireplace in the living area. An elevator runs from the three-car garage to the top floor. The HVAC and AV systems have been updated by Cascade Integration and High Tech Living, including a brand-new security system with 24-hour recording. Views abound, and the kitchen patio is a must-see. The backyard is level and lush, fully landscaped with Wells Medina plants and designed for privacy, with sound barriers and raised beds. Six-foot fencing with privacy trees as well as several specimens of magnolias make for a peaceful home life adjacent to two urban corridors. With easy access to East Mercer Way and I-90, the home is 15 minutes from downtown Seattle and 10 minutes from downtown Bellevue. SHARED WATERFRONT: 25% fractional waterfront ownership with private pathway to personal beach access for swimming and kayaking.
