Why Carpenter matters
Carpenter's body of work is the single most prolific in the 1920s Manhattan luxury cooperative cohort. Horsley enumerates Carpenter's broader corpus across 810, 907, 920, 988, 1030, 1070, 1115, 1120, 1150, and 1165 Fifth Avenue, plus 580, 625, 640, 655, 812, and 950 Park Avenue. Together these buildings anchor the contemporary Park Avenue / Fifth Avenue trophy market.
Carpenter at peak form produced the buildings widely considered the most architecturally consequential of the 1920s prewar luxury cycle:
- 1926 commission at 810 Fifth (boutique 12-apartment configuration; Rockefeller and Nixon)
- 1922 commission at 920 Fifth (his own residence)
- 1924-26 Carnegie Hill twins at 1115 and 1120 Fifth
- 1926 full-blockfront 173-175 Riverside Drive (Babe Ruth)
- 1925 / Kondylis 1998 condominium conversion at 610 Park
