In 2018, the current owners further elevated the property with the addition of a screened-in porch, pool, and pool house, seamlessly blending 19th-century craftsmanship with modern luxury.

All pool house, pool and patio furniture is included in the sale. Whether hosting intimate evenings or larger gatherings, the property accommodates entertaining with ease. Arthur was one of eight children of Charles William Richter, a German silversmith, and Anna Eliza Potter Richter, who emigrated from St. Croix and settled in Madison prior to Arthur's birth. He was raised just blocks away in the Richter Cottage, circa 1836, on West Washington Street. The Richter family played an active role in Madison's early commercial life, operating several businesses including a photography studio in the historic Richter Building, now home to the Coldwell Banker office at 168 South Main Street. Arthur's brother, Martin Luther Richter, owned the well-known Dovecote House on South Main Street. When Arthur purchased this one-acre parcel in 1871 for $500, it was considered the outskirts of town. There he and his wife, Frances Cornelia Fielding Richter, established a family home that would remain in Richter hands for three generations. His grandson, Charles Woodruff "Woody" Richter, Jr., became a beloved Madison figure as the town's longtime mail carrier. The property ultimately left the family in 1994, after which a series of thoughtful renovations enhanced the home's livability while preserving its historic character. In 2018, the current owners further elevated the property with the addition of a screened-in porch, pool, and pool house, seamlessly blending 19th-century craftsmanship with modern luxury. This is a rare opportunity to own a historically significant residence in Madison's esteemed Historic District-where preserved heritage, architectural integrity, and modern comfort coexist in perfect harmony.
