It'd be interesting to see a large/tall building with a back wall dedicated to an elevator grid. Each tennant, instead of a door to a hallway (or in addition to it) would have an elevator door. Press the button, the lift shows up, and it can take you to any other property on that building. Eventually you could merge this kind of thing with other buildings, forming a kind of grid. Going out for dinner? Ask Alexa for a ride while you're talking in the foyer, 20 seconds later doors open and you're whisked away to a nearby restaurant where all you have to do is exit the lift and walk to your table.
