This 1929 colonial-style house is typical of the houses built in Urbana-Champaign in its time. It was built with no insulation in the walls and only a thin layer of insulation in the attic and between the floors. It was originally heated by burning coal, but later switched to natural gas. At the time it was built, there was little concern about the environmental consequences of burning fossil fuels, including the threat of climate change.
