An additional family room with fireplace offers flexible space for relaxing, movie nights, or a home office. A covered area between the home and spacious 2-car carport creates the perfect spot for hobbies, gardening supplies, storage, or a workbench.

Located across from Homestead Park and West Mercer Elementary, and just a few blocks from the heart of downtown Mercer Island—grab coffee, stroll Mercerdale Park, visit the summer farmers market, or hop on the new light rail.
