McMansion is a pejorative neologism, coine by NY environmentalist Jay Westerveld, to describe a particular type of housing that is constructed in an assembly line fashion reminiscent of food production at McDonald's fast food restaurants. The term is one of many McWords. A McMansion often denotes a home with a larger footprint than a median home, an indistinct architectural style similar to others nearby, and are often located in a newer, larger subdivision or replace existing, smaller structure in older neighborhoods.
