It is five stories tall and three bays wide. The eastern (front) facade is done in terra cotta with details in iron and glass. The latter two materials are combined to create the building's most distinctive feature, the proscenium-style[4]arched window across the bottom two stories.[1]
The building was constructed in 1904 during an early 20th-century building boom in downtown Troy. It originally housed the R.C. Reynolds home furnishing store. The store's grand opening on September 16, 1904 was attended by a crowd of thousands. An article in the Troy Times praised the building calling it "one of the most attractive show buildings in the city".[5] It was almost demolished during urban renewal efforts in the late 1960s, but protests from residents and its listing on the Register helped to save it. In the 2000s, it became home to Light & Power Communications Ltd., a Capital District media company.[6] In 2020, the McCarthy Building was converted to luxury apartments.[7]
