The structure now known as the Workshop is believed to have been built as a summer kitchen associated with the original wood Assistant Keepers Quarters.  It has also been referred to as a “carpenter’s shed” or “paint shed.” Photographs indicate it has been located in its present location since the 1920s, but earlier photographic records are unclear, and it may have been moved to this location after the original wood assistant keepers’ dwelling was razed. Located in the center of the station, it was convenient for storing paint and tools used for maintenance.

The Workshop is a 14-foot by 18-foot wood-frame building is built on a concrete foundation with a cedar-single gable roof. The roof was restored in 2009. It has both front and rear doors, with fixed six-light sash on the east and south sides, and two single-light wood casement windows on the north side and fixed single-light windows along the remainder of the north side. The building is white with green trim.

A free-standing red brick chimney, work benches, and shelving populate its single room. The interior is light yellow with a gray floor.

The structure is a typical example of late 19th-century construction. The Lighthouse Board did not define designs for such ancillary buildings, so it lacks architectural significance specifically as a Lighthouse building. However, it offers a certain significance as part of the overall collection of buildings as stations often included several auxiliary buildings for storage, maintenance, and other purposes. It also has historic significance both in its original function and in its successive uses throughout the history of the station.
