A stack parking system usually needs the same floor space as one normal car parking slot, but it uses vertical space to park two cars. In most cases, a stack car parking system requires around 2.3 to 2.6 metres width, 4.5 to 5.2 metres length, and 3.5 to 4.2 metres height, depending on the car size. A car park stacking system is best for apartments, offices, hospitals, hotels, and commercial buildings where parking space is limited. https://www.icubeelevators.com/stack-parking-system/
