The AIA released some findings from their Home Designs Trends Survey from the first quarter of 2008, which discusses how, due to the weakened housing market, there is a trend to build smaller homes, which have greater accessibility for an aging populace, and a desire for spending money on improvements on the outside areas, which may be easier to do than improvements to the interior.
