The chef's kitchen features an oversized center island, custom Allikriste cabinetry, a professional-grade Wolf range, built-in beverage drawers, and abundant prep space.

Value check
Is the price right?
The internet’s favorite home-value number comes from a single automated model that has never seen the street, the finishes, or the view — which is why it routinely misses by tens of thousands of dollars. The edgeAI estimate combines multiple independent data sources with our team’s on-the-ground expertise in this exact market.
