In Spring and Fall, the Home Builder's Association in a city within commuting distance has a Parade Of Homes- free open house at selected new houses completed or nearly so- 25 to 35 of them. Always interesting and I know a few of the builders. Some of the houses are well beyond anything that would be practical for me and I visit those first. They have a newspaper insert with photo of each house, miniature floor plan, directions to the house and list of subs and suppliers for that particular house. This year, they list almost none of the HVAC contractors, but most list the supplier of the portable toilet. I wonder how they determine the important aspects of the build project.
