Description

Perched on the shores of Lake Washington, this distinct Italian estate extends over 100 feet of private waterfront. Striking walnut floors, custom woodwork, and imported Italian Albertini doors and windows display impeccable craftmanship. A timeless beauty elevated with modern convenience, as seen in the lavish dining room overlooking the lake with exquisite crystal details. Designed for a chef, the stunning epicurean kitchen is equipped with the finest appliances. The primary suite affords a sitting room to sip coffee fireside while taking in sunrise views and a spa-inspired marble bath to relax and recharge. Spend summers outdoors on the decks or gazebo and on the lake with a private dock. The pinnacle of living in the Pacific Northwest.
