 The interior of the building was termed " severely plain " and utilitarian for its simple design of two large rooms on each side with a central hall and stairwell . Each room was filled with natural light from the windows , and had a chimney for the iron stoves on the east and west ends of the building . The oak floors were installed in the early 20th @-@ century and the ceiling was covered with modern acoustical tiles . The third floor is a shallow attic that gives access to the cupola . The ceiling and roof framing is supported with two king @-@ post trusses at the ends of the main ridge . The basement is divided into halves and supported by summer beams that run the length of the sills and supported by posts on stone pedestals . By 1982 , the steel I @-@ beams were " recently " inserted under the floor joists and between the summer and the sills . The cellar also has an old furnace that is not in service due to the building using electrical heating .
