1120 lake sammamish se

Overlooking Lake Sammamish in a private, elevated setting, this custom residence captures 180-degree protected lake and mountain views—an increasingly rare vantage point preserved by the home’s sloped 17,188 sq ft lot. Designed as a refined treehouse retreat, the home offers an immersive connection to its surroundings with 10-ft ceilings and views on all 3 levels, filling the interior with natural light and a sense of tranquility. Crafted with clear architectural intent, the home features built-ins, custom cabinetry, window seats, multiple fireplaces, and integrated storage throughout. Multiple view decks are designed for entertaining and year-round enjoyment as spectacular scenery takes center stage. Thoughtful updates provide peace of mind: new roof (2025), zoned HVAC with 3 furnaces and 2 A/C units (2022-23), and 3 low-maintenance waterproofed decks (2020). The chef’s kitchen and great room form the heart of the home, where eagles at eye level, seaplanes, and expansive lake views create a setting that never feels static. The upper level offers a private primary sanctuary with library/office, spa-like bath, and versatile loft/wellness area. The lower level features a fully permitted 2-bedroom ADU with kitchen, living area, laundry, and separate entrance, offering exceptional flexibility for guests, multigenerational living, or income potential.
