About this home

Public Remarks: Impeccably maintained mid-century gem, on the market for the first time in 45 years! This fabulous 3-bed Ranch sits on a serene half-acre lot at the end of a quiet cul-de-sac in highly desirable New Berlin, adjacent to the NB Hills Golf Course. Timeless character shines throughout, with all original light fixtures, spacious original kitchen, and parquet wood floors in the DR. The inviting living room features a stunning floor-to-ceiling masonry wood-burning fireplace, perfect for cozy evenings. Downstairs, you'll find a partially finished lower level with a second WB fireplace and a generous family room, ideal for relaxing or entertaining. Every detail has been lovingly preserved, offering a rare opportunity to own a beautifully intact time capsule in a truly unbeatable location.
