Walter Beauchamp House  The Walter Beauchamp House is a historic house at 492 Prospect Avenue in Hot Springs, Arkansas. Built in 1905, it is a "double decker" single-family house, unusual both for its setting on a spacious lot, and for the style, which is generally uncommon in Hot Springs. Houses of this type are typically found on narrow lots in densely-built urban areas and have two units; this one is set on a larger lot similar to others in the neighborhood and has a single large unit. Walter Beauchamp, the builder, was a conductor on the Chicago, Rock Island and Pacific Railroad. The house was listed on the National Register of Historic Places in 1994.
