Regally commanding postcard views of the western shore of Bellevue’s Lake Sammamish, the European vision resonates with romance. A majestic soaring entrance with sweeping staircase introduces a flow of main settings that take the breath away. Old World, yet startlingly high-style with African moabi and walnut floors and black-and-white dichotomies, it brims with delightful serendipity. Beyond the main rooms, three levels house a high-tech chef’s kitchen, wine room, theater, gymnasium, wet bar, and array of bedrooms highlighted by a palatial master haven with opulent spa baths and dressing rooms. But the favorite spot is outdoors, on terraces enjoying the sandy beach and lake.
