Answers.Text: This solution looks nice but your prototype is only 1 plate shorter than mine. It does look like it should be possible to make it shorter though. And I like that it's the door that's rounded instead of the wall; in some circumstances that will be a huge structural advantage.

Answers.Text: It should be possible to make this a little shorter. One simple way would be to build a full size Technic brick into the floor rather than the half size one that I used. This would allow you to flip the pin at the bottom the other way around and allow the platform that the minifig is standing on to be lowered down to the level of the ground. That assumes that you have space to build into your floor, though.

Answers.Text: I played around with this solution and found a couple of issues. For one, I don't have enough technic beams to make this work, but that's not a flaw in the solution itself. The bigger flaw is that the ledge where the minifig stands can only stick out by one stud or else the door can't swing all the way open. I need at least 1.5 studs to fit a fig or else they lean awkwardly. (My use case is that the fig is a statue, not a character). Also due to my lack of technic pieces I can't build it well AND have a platform. It'd still be a great solution for a swivel wall with no platform though.

When I build it your way, with the hinge set on a jumper, I don't see an easy way to attach it at the top of the door and that makes the door too flimsy. When I use a 2x2 tile with a pin on it, this moves the door half a stud forward and then it rubs too hard against the frame and can't really be opened.
