The building is designed in the shape of a cross. A large central rotunda with a glass domed ceiling connects the four wings. The structure is four stories high. The first floor houses committee rooms for the House of Representatives and the Senator. The second floor houses the executive offices of the administration. On the third floor, offices for the Indiana House of Representatives are on the east side, while those for the Indiana State Senate are on the west side. Offices of the Indiana Supreme Court are on the north end of the third floor.Statehouse Guidebook, p. 9–10 The seventy-thousand volume Supreme Court Law Library is located on third floor. The third floor also holds the House, Senate, and Supreme Court chambers, and the fourth floor holds the Indiana Court of Appeals courtroom and the offices of nine of the fifteen judges on the Court.State House Guidebook, p. 11–12 The building was constructed for the purpose of holding the entire government of the state. Indiana is one of a few states that still have all three branches of government operating in the same historic building. For several decades, all the government bureaus were housed within the building, until the government again outgrew the structure; most of the state's bureaus have gradually been moved out of the building. In front of the State House stands a statue of Oliver Morton, governor of Indiana during the Civil War.
