17 Williams Street, Lewiston, MN 55952

Welcome to 17 Williams Street — a rare opportunity to own a well-built, energy-efficient duplex in a peaceful Lewiston neighborhood. Constructed with insulated concrete forms (ICF), this 3,300 sq ft home offers exceptional durability, quiet living, and year-round comfort. Each level features 3 bedrooms, 2 bathrooms, in-floor heat, mini-split A/C, vaulted ceilings, and an open-concept layout. Both units include private laundry and a smart, functional floor plan, plus a newer roof for added value and peace of mind.
