The Training School for Deaconesses was completed in 1909, independently of the plan. Cram presented to the trustees an extensive plan for all the structures on the grounds in October 1911, and the trustees approved the choir school the same month. The following month, the trustees certified plans for the Synod Hall, bishop's house, and deanery, as well as the never-built diocesan offices and canons' residences. A heating plant at the southwestern corner of the cathedral close (added to the plan in 1913), and two structures planned for the western boundary and approved in 1920, were not built. A shelter was built in 2015 for the cathedral's three peacocks, Jim, Phil, and Harry, who lived on the cathedral close from the early 2000s to 2023. Ithiel Town Building The former Leake and Watts Asylum building, designed by Ithiel Town and completed in 1843, is located south of the crossing, where the south transept would have been located. The building, designed in the Greek Revival style, was originally composed of five parts. There was a central pavilion with Ionic-style porticos to the south and north. The front entrance, located within the south portico, was approached by a wide granite staircase. The only decorative element was at the south portico's pediment, which was supported by six stucco-covered brick columns, topped by capitals made of wood. Brick wings flanked the central pavilion to each side, and originally contained wooden porches along their facades, replaced with iron balconies in 1888. Originally, there were common areas and staff rooms within the central pavilion, and dormitories for 300 children in the wings. When the Episcopal Diocese of New York acquired the site, the former asylum building served several functions for the cathedral. Between 1892 and 1899, it was used as an employee dormitory and construction offices, while the parlor hosted worship services. Afterward, the former asylum's west wing was used by the day school for the cathedral's choirboys between 1901 and 1913. Cathedral leaders had proposed demolishing parts of the asylum building, since it was in the way of the proposed southern transept, though these demolitions did not happen. Subsequently, the west wing was used by the Diocese offices, and the east wing by Cathedral offices until 1949. The building then became the "Exhibit Hall" and the top stories were removed sometime afterward. The structure was renovated in 2004–2012, becoming the "Ithiel Town Building". The Ithiel
