Homes being built nowadays in the US are considerably bigger than they were in the 1970s. And it’s not just extra bedrooms and bathrooms that are boosting house sizes either — home builders are tacking on significantly more parking space too.

The US Census Bureau and the Department of Housing and Urban Development released data on Monday detailing the characteristics of new privately owned residences completed in 2014. We looked into the historical data to see what some of the biggest changes over the decades have been for newly built, single-family homes.

One of the most dramatic changes was air-conditioning. Just under half of all houses completed in 1973 had air-conditioning, while an overwhelming 91 percent of homes completed in 2014 came with a cooling system.

Builders today are also less likely to make a family share a main bathroom: 40 percent of homes completed in 1973 were equipped with one and a half bathrooms (or less), but that percentage dwindled to just 4 percent last year.

Other trends we noticed? The carport is pretty much dead and most single-family homes built in 2014 were between 1,800 and 2,399 square feet, despite the ascendancy of larger houses.
