This scrolling exhibit highlights some of the changes to American homes in the last 110 years. Here is what it predicts for homes in 2020:
Houses are nearly three times the size of homes from 1900.
Two master bedrooms (one upstairs, one downstairs) is a growing trend.
Water and energy conservation systems are becoming mainstream.
Extra bedrooms are being replaced by specialized storage (i.e. bigger pantries and closets).
Home automation tech (remotely controlling locks, lights, HVAC, and appliances) is booming.
There are some major changes over time this period including increasing size (with decreasing household sizes), more of an emphasis on cars, and changes in interior design and layout that take advantage of new technology and different social arrangements but are also subject to aesthetic whims (floating staircases in the 1970s, floral wallpaper in the 1980s, etc.).
Also noted: the 2000s are said to be the decade where “McMansionism continues.”
