The ordinary house is built on a considerably smaller plot of ground, quite near to the dwellings around it. Some folks are ecstatic to have one.

According to the United States Census Bureau, the typical size of a new construction lot in 2018 was 8,982 square feet, or approximately one-fifth of an acre. In 2009, the median size of a residential lot was 10,994 square feet, or one-quarter acre.
