My BIL is a home builder. I do remember him saying there were a few pro and cons about them. I remember him saying that they can be quite expensive if adding them to existing structure in the interior of the building.. Boxing them and installing in new contruction shouldn't be that bad. Location plays a role.I don't think the mechanics are all that costly. I'm sure exterior would be a lot less expensive then interior. Ya know if you had rooms on top of each other on an exterior wall, I would think it can almost be prefab, punching through for the doors.
He has one that is SS that goes from the kitchen on the ground floor to a family/entertainment/bar room on the next floor to the movie room up stairs.
