What to do when there’s no foundation?
We did a major renovation over 10 years ago. As part of that reno we enclosed what used to be a porch. One forced hot water register was installed and the underside of the flooring was covered with insulation. The room is very cold. It is approximately 4 feet in the air supported on concrete filled tubes. Other than digging and pouring a foundation under this space is there anything else we can do.
