McMansion

A large and pretentious house, typically of shoddy construction, typical of "upscale" suburban developments in the late 20th and early 21st centuries. Such houses are characterized by steep roofs of complex design, theatrical entrances, lack of stylistic integrity and backsides which are notably less fussy than their fronts. They are often placed closely together to maximize the developer's profits and appeal to people who value perceived social status over actual, physical, economic or historic value.
