Similar to my other door model, with a door and hinges that pivot around the hinge, and a constraint on the doorknob so the latch retracts when it's rotated. Except, as suitable for a front door of an apartment, there is a deadbolt which has a similar constraint for its latch, a door limiter, and a peephole. The frame is thicker and modified to fit the limiter. Also the door is slightly more intricate, but not much. Use an enjoy and much as one can enjoy a door.
