Each room is 10 blocks high (save for the top most 2 rooms)... that is the wall is 10 blocks and the roof is a block above, so the outside wall is 11 blocks...if you don't look under the ground cuz then it's another block for floor. Between each floor I plan on putting a 2 block space.
So where is this stair way to go? The Foyer going above the throne room to what is to be a library.
The solutions i've come up with, neither i really like, is lower the throne room roof or heighten the foyer room roof to something like 40 blocks.
btw, the rooms on the left, pantry, great hall, and kitchen are going to get rearranged
The area in front of the Castle is going to be a garden/forest of some sort...which I have no idea how to design... and in front of that is going to be a moat.
And then to the left and right of the castle are supposed to be Barracks and a casemate.
Also... are there any mods that will allow me to convert all of one block to another...I want the entire castle to be in obsidian, but that's going to be impossible to find that much so I'm building it in cobblestone
