The dining area of my kitchen is built over a crawl space that's enclosed
by cinder blocks like the rest of the house. In the basement, there are
two openings to this crawl space, but they're only 6" high x 18" wide.

Your thoughts, please.

It is a more scientific approach than has been done over the years and make
some sense.
