About this home

A rare offering. This private, gated estate unfolds within a lush, enthralling landscape — serene, flourishing, and utterly its own. Inside, a well-curated floor plan balances gracious entertaining spaces with rooms built for everyday life, each one revealing quiet discoveries of beauty and craft. Minutes from Seattle, Bellevue, and the region’s finest parks, the estate feels a world apart — yet never far from it. More than a residence, this is a way of living — one maintained with the same care and devotion that shaped it. A work of art, and one that could not be replicated today.
