It features a full-height porch with Corinthian columns, a symmetrical facade and a side verandah with Doric columns. It was designed by the prominent Peoria firm Hewitt & Emerson, and no other Classical Revival residences are known in Pekin.","narrative":"Built in 1912 on a full city block at 420 Washington Street in Pekin, Illinois, this two-and-a-half-story brick mansion is a local example of Classical Revival residential design. Its hipped green slate roof, full-height entry porch with Corinthian columns, segmental pedimented doorway and symmetrical facade are typical of the style's early wave of popularity. A side verandah with Doric columns and a roof-line balustrade adds to the composition, and the original wide brick sidewalk remains. Inside are quarter-sawn oak floors, marble fireplaces, a ballroom in the attic and a large arched stair window. The Peoria firm Hewitt & Emerson prepared the plans in 1912, and the original blueprints were later returned to the house. No other Classical Revival residences are known in Pekin. The house later became law offices with few interior changes. A rear screened porch, a pool and a rebuilt garage are the main additions. The house was listed for its architecture.","period_of_significance":"1912","architect_builder":"Hewitt & Emerson","architectural_style":"Classical Revival","criteria":["C"],"status_note":"Rehabilitated for use as law offices (current function listed as Commerce - Professional); original interior largely retained.
