Garage with a basement
This is the second place(out of 100) that I have seen, a small garage(20 by 20) with a basement(exterior entrance). About four old rusty I beams and a steel ceiling are used to support the vehicle and the concrete floor.
Nor sure how well this works.
Its begging for clean up , ventilation and heat, and maintenance.
Grit blast, prime and paint?
These things have never been done ...for 50 years it appears.
