Does your house qualify for a Century House Plaque? It is an excellent way to give your house the honour it deserves. Due to continuous increases in our cost to produce the century plaques, we must increase the price to our cost +10%, which will be approximately $225 (tax is included). Send a request to oakbayheritagefdn@gmail.com with Subject Century Plaque. Include your name, house address and date of construction. We will ensure you receive a plaque with the date the house was built.
