I applaud this effort to not label every home you dislike a McMansion but this discussion of zoning in New Jersey suggests there is not a readily accessible term for disliked homes smaller than McMansions:
An association does run the new neighborhood, but the houses are not small. While they may not qualify as actual McMansions, they are bigger than they should be for the lots they are on and look faintly ridiculous. The project isn’t finished. Let’s see how well landscaping mitigates the problem…
Much of the objection is aesthetic. The Park Avenue and Whippany Road intersection is the gateway to Hanover Township coming west from Morristown and visitors should not be presented with an eyesore as their first impression of the township, residents say.
While McMansions are assumed to be larger than normal, what are the negative terms for smaller than normal homes? For homes with less square footage, the terms tend to refer to specific kinds of homes but without necessarily carrying the same connotations as McMansions. Condos. Townhomes. Starter homes. Split levels. Tiny houses. Perhaps the closest one is “double-wide” or “trailer home” but these are less common in many areas and/or are restricted to specific clusters or more rural areas.
At the same time, the small size of a new home or set of smaller units doesn’t necessarily mean that the size and design escapes scrutiny. The homes here are considered an “eyesore.” Elsewhere, others argue that multi-family units or smaller homes compared to everyone else may just actually lower property values through offering cheaper housing units or destroying the community’s character.
