Like many U.S. state capitols, the Georgia State Capitol is designed to resemble the Neoclassical architectural style of the United States Capitol, in Washington, D.C. Former Confederate general Philip Cook was a member of the commission that oversaw planning and construction of the building. The commission engaged architects Willoughby J. Edbrooke and Franklin Pierce Burnham, of Chicago to design the building and Miles and Horne of Toledo, Ohio for construction. Work completed in March 1889. Sculptor George Crouch executed all the ornamental work on the building. The Capitol faces west on Washington Street. The façade features a four-story portico, with stone pediment, supported by six Corinthian columns set on large stone piers. Georgia's coat of arms, with two figures on each side, is carved on the pediment. The Capitol's interior represents the 19th-century style of its time. It was among the earliest buildings to have elevators, centralized steam heat, and combination gas and electric lights. Classical pilasters and oak paneling are used throughout the building. The floors of the interior are marble from Pickens County, which still produces marble today. The open central rotunda is flanked by two wings, each with a grand staircase and three-story atrium crowned by clerestory windows. The Capitol building has undergone frequent renovations to adapt to the growth and change of government. Originally constructed from terra cotta and covered with tin, in a 1958 renovation the present dome was gilded with native gold leaf from near Dahlonega in Lumpkin County, where the first American gold rush occurred during the 1830s. For this reason, legislative business is often referred to as what is happening "under the Gold Dome" by media across the state. The statue Miss Freedom has adorned the dome since the building's opening. In 1997, the House and Senate chambers were restored to their 1889 appearance with replicated decoration and color schemes. This included the demolition of damaged plaster, the reinstallation of flat plaster at the dome, columns, and walls, and a decorative painting in the House and Senate Chambers.
