A storey of a building that is underground is often called a basement or basement level. In terms of buildings, there is a recent one of a section of dis-used and abandoned Los Angeles US underground rapid transit tunnel that had been discovered during building remodeling and goodyear rubber or firestone (I forget what one) had purchased the rapid transit line and dismantled it in favor of tire sales.
The prefix for storey is "multi-" as in "multi-storey building."
The German word for car park is "Parkplatz". Also: multi-storey carpark - Parkhaus underground carpark - Tiefgarage
