John Moore House is a pioneer home built in 1824 north of the village of Sparta, Ontario on land inherited from the builder's father, Samuel Moore U.E.. It is considered a good example of pioneer architecture and construction in Elgin County, and a valuable relic of early settlement days in Southwestern Ontario, if not in the province. It is an example of Georgian architecture, a two-storey structure of stone and brick, it features a symmetrical five bay front façade with a central door and two sets of flanking windows on the main floor, and five on the second storey.
