Stairway / Ramp Design

I came across this stairway / ramp design, i thought it is quite brilliant in the sense that it solves the problem designers have been experiencing for years. Too often you come across a building entrance which has a staircase and a ramp right next to it, to be honest it never felt natural to me and it often seemed to be very bulky from a visual perspective. In my opinion the connection between the two elements works beautifully together, streamlines the circulation and connects abled and disabled human beings, to me the separation between the two elements always felt discriminatory. Whats your thoughts?
