In 1977 a new addition was completed at a cost of $180,000, locker rooms and the upstairs bar and lounge were enlarged by 15 feet.

This allowed for the construction of a board room, a new bar, as well as a professional kitchen facility.

The club has five sheets of curling ice, lockers on the main level and a lounge upstairs that was refurbished in 2017.

The Chatham Granite Club has sent two teams to the Brier, in 1949 and 1953 when Peter Gilbert won the Provincial championships.

Peter Gilbert is the oldest curler to ever compete at the Brier, at the age of 73.
