Spectacular Mid-Century Modern masterpiece by iconic developer Joseph Eichler! As you enter this sensational home you are greeted by a great room boasting expansive walls of dual-pane glass, soaring open beam ceilings, sleek concrete floors, & a floor to ceiling fireplace. To your left is a stylish kitchen featuring custom Kerf cabinetry, upgraded appliances, & amazing quartz countertops. The dining & living areas are bathed in natural light, & offer beautiful views of the splendid yard. Moving through the home you'll discover 3 guest bedrooms & a super chic guest bathroom. Next up is the extraordinary primary suite with a glass sliding door offering access to the rear yard. The ensuite bath is a veritable spa- natural stone floors with radiant heat, freestanding soaker tub, walk in shower & Duravit bidet. Finally, step outside to explore your very own private resort. Amenities include a shimmering salt water pool, spa & water feature, gas fire pit, Goodwin-Cole electric retractable awning, & convenient 1/2 bathroom. This secluded oasis backs up to the Willoughby Slough, which means no rear neighbors. The owner has made extensive additional improvements, too numerous to mention here, a complete list is attached. An incredible opportunity to call this architectural treasure home!
