Exceptional Development Opportunity on Mercer Island. A generous 22,000 sq ft corner lot in one of MI’s most desirable neighborhoods. Pre-app with the City is complete with preliminary subdivision approval granted—ready to be divided into two lots. The lot’s regular shape supports optimal design flexibility, allowing future homes to maximize the 40% FAR. Enjoy an unbeatable location just minutes from the lake, parks, shopping, and top-rated schools—all within walking distance. An existing home on the property has been modestly updated. Whether you’re a builder, investor, or homeowner with vision, this is a prime opportunity to capitalize on the scarcity of developable land on MI. Bring your team and start the permitting process.
