(If you get the coords, the Y value is very important in this case... I would get it to where you have:
[][][][][][][][][][][][][][]
[]
[]
[]CC CC CC CC[]
[][][][][][][][][][][][][][]
(Side view cutaway, this will include both the ceiling and the floor of the room, your Y value is the block your feet/legs currently occupy.)
So, if, when you are standing on the floor, your elevation (Y) is 20, your floor would be 19, and your ceiling would be 23.
This way, I am exporting a room, and you can import it wherever you want (as a small building on the surface, underground room, inside mountain room, whatever.
