The group “Save Miami Beach Neighborhoods” is looking for help in fighting McMansions:

Miami Beach homes comprise a variety of architectural styles that reflect the history of our City, which is not yet 100 years old. Unfortunately, recent zoning changes have allowed for out-of-scale McMansions which threaten the historic character, authenticity and desirability of our single-family neighborhoods.

Our goal with Save Miami Beach Neighborhoods is to ensure that new construction is in line with existing neighborhood context. We want to stop oversized McMansions that are popping up seemingly all around us…

As homeowners and concerned residents, we must act to limit new construction size and scale before our neighborhood character is lost forever.

I would say the one photo of an 18,000 square foot McMansion in the neighborhood is pretty emblematic of what critics do not like about McMansions: large, taking up much of the lot, unusual design compared to the house next to it, and much larger than the next house (which is probably only 5,000 square feet).

At the same time, I wonder if outsiders would look at this and say it is simply an argument between wealthy people about something nebulous like “community character.”
