Newcomb and designed by local architect Harvey Chatten with Ernest M. Wood. Its massive Indiana limestone walls, carved leafy ornament, copper trim and red tile roof reflect the Richardsonian Romanesque style. The interior is finished in oak, birch, mahogany, cherry, sycamore and butternut, with carved mantels, ceramic tile, gold leaf accents, and stained and beveled glass windows. A grand staircase rises through the center of the house. The home stands on two and one-half acres in what was Quincy's most prominent residential area, near other notable houses. It was built when Quincy was a booming commercial city, and Newcomb reportedly wanted to employ local architects and craftsmen. Later used as a college dormitory, it became home to the Quincy and Adams County Museum, which planned to restore its original character.","period_of_significance":"1800-1899","architect_builder":"Harvey Chatten, Ernest M.
