270 Maple St

About this home

Built in 1879, 270 Maple Street—historically known as the Frederick Harris House and more recently as Valentine Mansion—is a remarkable 30-room historic estate spanning 11,102 square feet. The largest single-family home in Springfield’s “City of Homes,” it features a 40-foot grand ballroom, ornate floor-to-ceiling hand-carved fireplaces, 12 bedrooms, 6.5 bathrooms, and what may be the city’s finest residential view. Set on 2.93 acres, with an additional 0.99-acre lot available, the property currently operates as an owner-occupied short-term rental B&B. Built for banker Frederick Harris and social activist Emily Osborne, the home offers multiple primary suites—including a rare adjoining his-and-hers suite—coffered ceilings, six sets of pocket doors on the first floor alone, and exquisite original woodwork, tile, brass hardware, and metalwork. Energy-efficient mini-splits, stainless steel appliances, a nine-zone sprinkler system, ample parking—this property has it all.
