An upstairs room in the tower was provided for the keeper, who was required to stay at the light at night and in rough weather. This situation was not ideal for the keeper as he was forced to also maintain a home on shore for his family. A formal dwelling on the cribwork was finally constructed in 1885, and this structure was transferred to a new concrete and steel pier built in 1892.
On January 15, 1907, a second lighthouse was established on Bunker Island to aid vessels around the northwest extremity of the island. This wooden pyramidal tower, twenty-two feet tall from its base to the top of the ventilator atop its square wooden lantern, was known as the Bunker Island North End Light and is no longer standing.
Keeper Jules Cottreau and his wife raised six children at the Bunker Island Lighthouse between 1930 and 1959. The top of the pier where the lighthouse stood had a diameter of just 11 meters, which didnít provide a lot of play space for the children. After Jules Cottreau retired in 1959, the present lighthouse, which does not have a living space, was erected. The beacon was originally exposed until a lantern room was added in 1984.
