This is one of the few remaining examples of the Regency-Georgian tradition as it evolved in this area from the United Empire Loyalists. A two storey frame dwelling, the house sports several features indicative of mid-nineteenth century architecture. It retains its symmetry, fine proportions, small-pane windows, low gable ends, and its doorway with sidelights and transom.
Though it does not appear on Sandford Fleming's 1846 Plan of Peterborough, the house was probably built shortly thereafter: a two storey frame house appears in the 1851 Census, owned by John Williamson, merchant tailor. In 1866, the house was sold to James Campbell, a general merchant, who maintained ownership at least until 1880. In 1882 the property decreased in value as part was sold to the Midland Railway for their branch line between Peterborough and Lakefield. By the 1890s the house was owned by William Green, a painter, and Francis Green, both of whom were grandsons of Benjamin Green, the Soap and Candle maker of the 1850s.
Much later, during the 1950s, two of the windows on the west end of the building were converted into doors and an exterior stairway leading to the second floor was added. The porch, too, was probably added at this time. The door leading onto the balcony was originally a window. The house has never been painted - it retains its original stucco finish.
