I could be wrong but not sure if you meant the photos to be showing the crawl space, dear Ataloa (peace, luv!). They're not; those are of the "basement". I realize how "confusing" this might all sound, so maybe some more pics will help:
The crawl space is accessed through a small door just past the water heater in the laundry room (which is on the same level as the office). The office and laundry are about four feet lower than the main floor and the crawl space is under the main floor. These are the steps leading from the office/laundry level up TO the main floor:

So it's high enough under there so's I can sit up straight (as can someone taller) but I have to crawl until I get to where I want to be. It's LIGHTED under there, too, though - just flip the switch right inside the little door... and wahhhhhhh! Between the light bulb and sunlight through the vents, it's actually pretty visible under there.
So, it's really not all that bad. Not really... although it's not necessarily my FAVORITE place in the house, either - LOLOL!
Peace... and hope ya'll enjoyed the mini-tour through this part of my house!
