Moving stairs aren’t just something from a fantasy novel, it’s in fact the solution that the Allgood Trio company came up with. What looks like regular stone steps, are in fact retractable stairs! It doesn’t affect the building’s exterior: only a wheelchair button is visible. Look what happens when the woman pushes this button in the video down below. Amazing invention, isn’t it?
