The Classic Six Apartment is the most common New York City apartment type built before 1940 and is an iconic New York Apartment style. The Classic Six is generously sized, and designed for another era: one of tiny bathrooms, live-in help, and a time when cooking was not a family activity. There are six rooms, not counting bathrooms, foyers, or corridors:

  • Living Room
  • Dining Room
  • Kitchen
  • 3 Bedrooms


Apartment buildings began as an economic necessity and a fashion trend; more homes could be built on the same land (better value for the builder), and Paris was doing it! In New York City, the apartment building achieved the form we now consider “classic” between WWI and WWII due to massive economic and social upheavals resulting from international war. Before WWI, apartments were novel alternatives to row houses (a brownstone is a row house); the early apartments emulated houses, but built on the same level. These developed into a successful formula with a consistent set of characteristics and amenities. As WWII approached, the apartment was a known solution that could be adjusted and optimized in relationship to the fluctuation of the economy.

Typically, the original condition rooms are separated by glass-paned and wood-paneled doors. There are zones for entertaining—Foyer, Living Room, Dining Room—for sleeping, and for the servants. Entertaining rooms are adorned with wall moldings and white-oak hardwood in parquet patterns, while Bedrooms, and the long corridors that separate them have red-oak strip-flooring. The older the building is, the higher its ceilings, the larger its windows and rooms, the wider its corridors, and the more generous its crown moldings. Newer buildings will have more bathrooms


The Classic Six was built for a time of live-in servants, clearly separated spaces were predominant and plumbing was limited. As times have changed, these  Classic apartments flourish when they are adapted for contemporary life.
