In the nineteenth century the area of Baileyville in Middlefield was an active industrial district. The building at 93 Baileyville Road was probably constructed around 1850 as an outbuilding for one of the mills along Ellen Doyle Brook. In 1876 it was converted into a residence by George W. Miller to house an employee of his phosphate mill. In 1921 it was purchased by the Lyman Gun Sight Corporation to house factory workers and their families.
Once part of the property of the Isaac C. Lewis Cottage in Branford is a small clapboard barn with a cupola. Built around the same time as the cottage (c. 1882), the barn is known as the Toolshed. It was originally behind the house, but has since been moved closer to Thimble Islands Road and has been adapted for use as a summer cottage.
Adjacent to the Rising Sun Tavern in North Haven is a barn on the same property that was originally located on Long Hill Road in Guilford. Built circa 1820-1830, the barn was moved to North Haven in 1999 and rebuilt. The original post and beam construction was maintained with few timbers needing to be replaced, although new siding was required as the original had deteriorated.
Currently owned by Planned Parenthood of Southern New England, the building at 45 Franklin Street in New London was built in 1892 as the carriage house of the Elisha Palmer estate. It originally stood at the corner of Broad and State Streets, behind the New London Courthouse, but was moved to its current address in 1982 to make way for a parking lot.
According to the barn survey information at Historic Barns of Connecticut, the barn at 41 Hebron Road in Andover dates to 1780. An English side-entry barn, it was moved to its current address from further up the road. Its owner dismantled and rebuilt it in 1998 to reflect its original period. The nomination for the Andover Center Historic District dates the barn to c. 1850. The barn is associated with the Phelps-Bingham House, a colonial house across the street.
On the northwest corner of the Bradley-Wheeler House property in Westport is a heptagonal (seven-sided) cobblestone barn with an octagonal roof. It is thought to have been built circa 1847 by Farmin Patchin, a mason and blacksmith who owned the house at the time. The original uses of the barn are unknown, but it was possibly a smithy. The northwest corner of the building was originally attached to a wood frame barn that is no longer standing. Renovated in late 1980s/early 1990s, the barn is now home to the Museum of Westport History run by the Westport Historical Society.
