The David Laidlaw House consists of a one and a half-storey stone house in the vernacular “Rideau Cottage” style which became the most popular form for a farm dwelling in Ontario between c1840 to c1875. Begun in 1849 and completed in 1852 by David Laidlaw II from locally quarried limestone, it still stands today as an important landmark in the area. Its exceptional heritage value is seen in heavy, well-cut corner quoins, stone lintels over most of the windows, side-lights and transom around the front door, arched window beneath gable roof-line with radiating stone voussoirs, two chimneys and the symmetrical façade. The 1842 census records ownership by David Laidlaw, who had emigrated from Scotland in 1839 to farm in Ontario. Following his death, his son, David Laidlaw II constructed the stone house that stands today. David Laidlaw III retained ownership of the house until his death in 1905.
