About This Home

612 Saint Lawrence Avenue

Rare Find! Impeccably restored Italianate home in Janesville's Courthouse Hill District. Named for one of the town's early business pioneers, the Lucius N. Williamson House was built in 1877 and is a contributing property on the National Register of Historic Places. Thanks to proud caring owners over the last 148 years, this 3,350 sf ft, 4 bed, 3 bath home has been immaculately maintained and updated. Tall ceilings and windows, decorative moldings, showpiece fireplaces, and original hardwood detail abound. Tastefully remodeled kitchen and bathrooms. Great outdoor living with large 2 tier composite deck. Beautifully landscaped and lovingly tended grounds reminiscent of an English country garden - complete with self-contained recirculating waterfall! Wonderful historic walkable neighborhood
