Houses are changing. Anyone buying a new home in 2018 expects the home to be quite different from one built in 1918, of course.
What “new features” is the typical buyer of a new home seeking out? It depends. Some buyers are looking for a foyer with a 20-foot ceiling and a master bathroom with a big Jacuzzi. Others, including the typical GBA reader, are looking for low energy bills and superior indoor air quality.
A beautiful house from 1918 probably included a large coal bin in the cellar. These days, coal bins are obsolete. If you want your new home to be green, then you probably realize that many of the must-have features of decades past are as obsolete as a coal bin.

A well-insulated house has as few bump-outs…
