Hey there. You see, I always wanted to make a Tardis in Minecraft that would fit a wizard. I made many different interiors, but I think my current one's the winner. I based the form on the wooden console part in the 11th Doctor's Tardis in 1.7.10.
This console was my inspiration:
I just made the walls higher, changed the floor and the roof. As for the walls, my main problem in the former interiors where I placed command blocks at the roundel part was where to put my bookshelves. Suddenly I had a realization: Why not putting the bookshelves in the place of the wooden walls? So I did it. I just can't decide which roundels I should use. If you have a suggestion, please say so. Enjoy!
Please note: the enchantment tables on the picture are there where I usually put the command blocks, the tables are usually at the bookshelves.
