Typical storage level, levels 4 to 16. For the automated garage portion of the structure, the average level height for passenger cars can be as little as 7 feet deck to deck and 8 feet deck to deck for SUVs. These smaller heights deck to deck can help contribute to a 30% plus savings in construction materials used for height relative to typical floor to floor heights of 10 to 11 feet or more, which include clearances needed for ventilation, piping and wiring on floors used for conventional purposes.
