Ed gets some fresh air after sanding down all the walls inside the house. Habitat houses are made by the work of volunteers who drive their personal vehicles and give their time to houses like this one. A Habitat house costs about $40,000, which is about half of what the average general construction house in Carbondale costs. The homeowner's price for the house is kept to a minimum by only being charged the cost of the materials put into the house, everything else is generally volunteered.
