What is the difference between Pre-War and Post-War apartment buildings?

On a simple level, each designation denotes the time period when an apartment building was built in relation to the end of World War II (i.e. 1945).  Generally, most people have a distinct preference of one style over the other, since they can vary widely in many respects.

Pre-War Buildings
Pre-war apartment buildings were built before 1945 and generally display more character than their post-war counterparts.  These buildings are typically walkups, townhouses or low and mid-rises (10-20 stories or so) with older plumbing, fixtures and details.  Apartments (as well as common areas, hallways and the lobby) may have certain features that are hard to find in many post-war buildings, such as moldings, decorative trim, antique lighting and a variety of architectural excellence.

Pre-war units are known for higher ceilings, hardwood floors, thick walls, fireplaces and other desirable finishes.  Over the years, some owners and landlords have upgraded their buildings and units with modern appliances, plumbing and other contemporary items, while maintaining their aesthetic appeal.

Post-War Buildings
Post-war buildings were built after 1945 up until the late 1970’s.  They may lack the “charm” of pre-war buildings, but they make up for it with other benefits.  Many post-war buildings have doormen, laundry facilities and may even have in-house gyms, sundecks and other amenities.  Most units are characterized by box-like, standard layouts with 8-foot ceilings, but may feature upgraded finishes, larger windows and a ‘newer’ feel in some respects.
