The Lake–Peterson House is one of the U.S. state of Illinois' finest examples of Gothic Revival architecture, specifically Victorian Gothic. The asymmetrical two-story residence is constructed of yellow brick and sits upon a stone foundation. Its steeply pitched roof is clad in slate tiles and each of the four sides of the original home features a decorative gable. The house also features tall brick chimneys with corbelled chimney caps, dormers, bay windows and a large veranda. The architect, if there was one, is unknown, though it is probable that Lake himself was the builder. One possibility is that John Lake obtained the architectural plans in England, his native land, where he had returned from as construction on the house began in 1873.
