I'm looking for detailed info regarding the elevator shaft dimensions for a project involving a 2-story structure with a basement designed for 2 people. The design specifies a shaft width of 270 cm and depth of 260 cm, accounting for a staircase that wraps around the elevator. Can you confirm the minimum dimensions required? Specifically, I need to understand if a shaft width of 130 cm and a depth of 210 cm would be feasible, given the 70 cm-wide steps. Your prompt feedback on this would be greatly appreciated!
