the bigger and bigger we get ...

There's a perception that the Tucson Foothills are becoming, or have become, McMansionland. At the same time, everything that I read suggests that home buyers are shunning McMansions and leaning toward more reasonably sized homes.

Sales of larger homes did increase in 2004 and 2005 in the Foothills - while sales of smaller home remained steady during that period - but by 2006 large home sales started to fall, along with sales of every other size home.
The chart illustrates sales over the past five years for homes in two size ranges, 0 - 2500 sf (what I call smaller homes) and 4000 - 6000 sf (McMansionland) 
Sales of smaller homes appear to have dropped more dramatically than the larger ones, but they're dropping from a much larger base. And as a portion of the total homes sold, sales of smaller homes have remained very consistent over the years noted.
During that time sales of smaller homes averaged a very tight 47% of all homes sold in the Tucson Foothills.
While sales of McMansions averaged just 9% of all homes sold. 
And even larger homes, those over 6000 sf, were a minute portion of sales (about 1.5%) during those five years.

I think part of the perception that larger homes are taking over, has to do with the fact that the larger homes, are larger, and more visible, they stick out more, you can't help noticing them. 
When you drive around the Foothills, almost all the homes you see being built, look like small castles. And lots of them are being built near the road, so you can't miss them.
And there are lots of larger homes for sale. 137 in the Tucson Foothills today, that are 4000 sf or larger.
That's 23% of the total inventory of homes for sale in the Foothills.

Here's the problem. Since the year 2000, homes that are 4000 sf or larger have never represented more than 11% of the total homes sold in the Foothills in any one year.
