Jacob and Frederick T. Youngs. After the 1947 Diocesan Convention, the bishop moved into the upper two floors of the deanery, and the old bishop's house was turned into administration offices. Residential buildings In 2008, the cathedral leased the southeast corner of its property, which contained the cathedral's playground and Rose Garden, to the AvalonBay Communities, which built a luxury apartment building called the Avalon Morningside Park. The project includes 295 apartments, of which 20% are affordable housing units, as well as replacement rose garden. The cathedral leased the northeastern edge of its property, formerly a parking lot, in 2012. The lessee was the Brodsky Organization, which built a residential building called the Enclave between 2014 and 2015. The Enclave consists of 428 rental apartments in two 15-story buildings, separated by the passageway leading to the northern transept; an underground gallery connects the two buildings. Both developments leased the land from the cathedral for 99-year terms. The lease on the land under the Enclave pays the Cathedral about $3 million a year; the lease on the Avalon, about $2.5 million. Art, activities, and exhibitions Concerts and special events The cathedral's interior is frequently used for concerts, performances, and other special events. Recurring events The cathedral has an annual New Year's Eve Concert for Peace. The Postlude to Act I of Leonard Bernstein's opera Quiet Place received its New York premiere at the 1985 concert. The 1990 concert was a tribute to Bernstein himself, who helped found the event and had died two months earlier on October 14. Paul Winter has given many concerts at the cathedral, and the Paul Winter Consort are the artists in residence. Among the major musical events that takes place every year is a celebration of the feast day of St. Francis, when the Paul Winter Consort participates in a liturgical performance of Winter's Missa Gaia (Earth Mass). The musical group also performs at the annual Winter Solstice program. One-time events The cathedral has also been used for several individual events: Duke Ellington's Second Sacred Concert, of his original sacred music compositions, premiered at the cathedral on January 19, 1968. When construction on the south tower restarted in 1982, French high-wire artist Philippe Petit walked on a tightrope stretched across Amsterdam Avenue. Petit was also the artist-in-residence at St. John's starting in 1982. In 1990, the avant-garde musician Diamanda Galas performed Plague Mass, a culmination of
