Description
The Mathieson House is located at 109 Wellington Street North, on the southeast corner of Widder and Wellington Streets, in the Town of St. Marys. The two-storey buff-brick residence was constructed in 1874.
The property was designated by the Town of St. Marys in 1989, for its architectural value or interest, under Part IV of the Ontario Heritage Act (By-law 80-1989).
Heritage value
The Mathieson House was constructed in 1874 for Dr. John Hugh Mathieson and his wife, Mary Mathieson. Dr. Mathieson was an outstanding doctor and visionary leader who made significant contributions to the St. Marys community. Mary Mathieson, John's wife, was the daughter of prominent pioneer settlers Milner Harrison and Catherine Howard.
The Mathieson House is a fine example of Italianate architecture. Constructed by local builder Robert Barbour, the house displays elements comparable to that of other Barbour-built homes, including Mount Pascoe, at 89 Ontario Street, which shares similar room arrangements and window and door surround details. Characteristic of Italianate architecture, the house features a projecting bay window and a portico on the façade, corner quoins and brackets beneath the roof eaves. Also of note is the veranda, which spans the façade and south elevation and features a decorative balustrade.
