An oversized bathroom brings in beautiful natural light and features a large walk-in shower. Both bedrooms offer high ceilings and thoughtfully designed storage, with the secondary bedroom featuring a built-in loft bed that maximizes space and adds charm. Downstairs, the full-size, full-height basement is a standout: pristine, wide open, and ready for workshop use or future finishing.
