It was designed by the prominent architect Martin E. Thompson. Its red brick walls contrast with stone lintels, enframements and a beltcourse, and its north entrance enframement is especially noteworthy.","narrative":"Completed in 1843 on Governors Island in New York Harbor, this two-story brick building was first built as quarters for the commanding general and later served as a hospital. It was designed by Martin E. Thompson, a prominent architect who had also designed the Second Bank of the United States and had been in partnership with Ithiel Town from 1827 to 1829. The nearly square building sits on a random ashlar basement, with upper walls of common-bond brick, a wide stone beltcourse and a simple dentiled cornice. Ten masonry steps with curving iron railings lead to an entrance with a plain stone frame and low pediment, and a cast iron balcony projects from the north facade. The nomination values it as a very restrained example of Greek Revival design, noting its disciplined scale and the contrast of red brick with stone trim. It remains in excellent condition on its original site and is used for officers' apartments.","period_of_significance":"1843","architect_builder":"Martin E.
