What is the biggest layout flaw in this NYC studio apartment?
Pre-war New York City studios built before 1940 frequently placed bathrooms at the interior of the unit, accessible only through sleeping alcoves, due to the era plumbing constraints and building codes. This layout was standard in tenement and railroad-style buildings where pipes ran through the center of the structure. Modern NYC building code requires direct hallway access to bathrooms, but existing units are often grandfathered in, leaving renters to deal with a layout that makes overnight guests or roommates practically impossible.
