McMansions are also non-functional buildings. It would be possible to ape the 'incremental build' style of a building that's been around for 100s of years without the aesthetic dissonance and massive space wastage of the average McManison. If you have a different style of window in every fitting without a strong aesthetic tie then you've just raised the build and maintenance cost of the property for no reason except cargo cultism.
