At 123 Main Street in the Rockfall district of Middlefield is a Greek Revival house built between 1845 and 1847. It is unusual in that the entrance is on the west side of the house instead of on the front facade that faces the street. Originally, there was also a door on the east side. The multiple entrances provided access to what was built as a boarding house for workers employed at the mills along the Coginchaug River. Now a two-family house, the building was erected by William F. Boardman, who also built another boarding house just to the west.
