Prime 11,675 sq' lot on Mercer Island’s coveted north end, ideally positioned to enjoy both east and west sunlight. Dream big here: design a custom home with potential for a daylight basement and two stories (buyer to verify), plus the opportunity to create a beautiful, usable flat backyard. Existing 3,330 sq' home presents an opportunity for a full-scale renovation or new construction. Just a few blocks north on 80th and you’re in the heart of Mercer Island—grab coffee, stroll Mercerdale Park, visit the summer farmers market, or hop on the new light rail. Head a few blocks south to Homestead Park and West Mercer Elementary. Bring your builder, architect, or vision... this is a rare chance to create something truly special. *VIEW BY APPOINTMENT ONLY*
