How to do a laundry shoot through a wall

We're in the process of building a house and they're about to put the wiring in so it would be the best time to add this. On the other side of one of our bedroom walls is the laundry room and I would really like to have a hidden laundry chute that just goes straight through with no gravity involved.

I like to have the door hidden behind a picture frame with other pictures on the wall to make a gallery sort of thing. What kind of hinges would I use for the picture frame so it doesn't jut out too far? And how would I make the edges of the cut out wall look professional so it's not just drywall?
