The three large towers on Tudor City Place (Prospect Tower, Tudor Tower, and Windsor Tower), Woodstock Tower, and Hatfield House were built as apartment hotels – legally permitted to be taller than conventional apartment houses – most of whose units, including many single rooms called "efficiency" studios, had Murphy beds and serving pantries but no stoves. They were marketed to single people and childless couples, young people who in the past would have lived in brownstone boardinghouses, and as "pieds-à-terre" for businesspeople and professionals who, rather than commuting daily, would spend one or two nights in town each week. At one time these efficiencies developed a reputation as "love nests" for mistresses and prostitutes. As co-ops, some have been combined into larger apartments. These buildings also included a few apartments with full kitchens, and penthouses with roof terraces. The Manor, The Hermitage, The Cloister, Essex House, Haddon Hall, and Hardwicke Hall were all built as traditional apartment buildings with units ranging in size from studios to six rooms.
