Reason for Designation

Historical Reasons

The Terwillegar House, built in 1857, is recommended for designation for historical and architectural reasons as it has been in the Terwillegar family since 1872. The house is a Georgian style fieldstone dwelling, considered to be the traditional style of Upper Canada and representative of the dwellings of its earliest settlers. The prominent façade of this simple example has three bays (two windows and a door) and faces south. It has a storey and a half extension to the north (rear) that created the T-plan design typical of the first half of the ninetheenth century. The rear extension is the original and served as the kitchen wing, reducing the risk of fire in the main dwelling.

The designation applies to the portion of the property containing the Terwillegar House, comprising approximately 0.4 hectares (1 acre) of land loacated at 3188 Grandview Street North and particularly described as Part 1, Registered Plan 40R22714. The designation is to apply to the entire original structure of the house.
