Following the war's conclusion, the structure was restored to its original condition. It was then occupied by banker Nathaniel Prime, possibly either between 1810 and 1831, or through the 1840s. The structure then became the Washington Hotel, which opened in 1854, although one source says that the house was used for entertainment as early as 1794. Sometime in the mid-19th century, the building was expanded: a drawing in the 1859 Norton's Handbook of New York City shows the hotel as being four stories tall. Adjoining the hotel was the residence of John Watts, built in 1750 on the site of the current IMM Building. It was connected to the Washington Hotel by a temporary bridge that was installed whenever the Watts family held large events. Washington Building In mid-1881, Cyrus West Field paid $167,500 for the Washington Hotel and $70,000 for Caroline W. Astor's adjoining house at Battery Place and Greenwich Street. The hotel's furnishings were sold off that December. The prior month, in November 1881, Field had announced that he would host a competition among six of the city's most reputable architects to design the Washington Building, a commercial building, on the hotel site. The winning architect would be paid $5,500, and the other architects would be paid $500 each for submitting a design. Edward H. Kendall won the commission and prepared plans for a Queen Anne style building on the site. The Washington Building Company was set up in June 1882, upon which title was transferred to said corporation. The structure was erected by W.H. Hazzard & Son and was completed in 1884 at a final cost of $900,000. The Washington Building was often referred to as the Field Building, after its developer. The Washington Building was originally a 9- or 10-story structure rising , covering . The building was faced with red brick and sandstone, and the main entrance was through Battery Place to the south. The corners contained five-story-high columns of overhanging oriel windows. The structure was C-shaped, surrounding an interior courtyard on its north side. It initially contained four elevators, but two more were added in the 1890s. As originally designed, there were to be 17 offices on each floor between the third and ninth floors, and there were "about 860 windows and 358 rooms" in total. Tenants included the Statue of Liberty construction committee, the Manhattan Hay and Produce Exchange, the Postal Telegraph-Cable Company,
