So here is my current base. I started out hollowing out the tree, and had my base there, but I expanded into the hill instead now. So this is outside, don't see much, secret door in tree (not really useful, since my kitchen entrance is just left of there

).
A little farm I have just made, need to expand on it, so my kitchen can have a use. Also a small pond with shells, which make pearls.
So this is my WIP entrance of the tree, still working on that. It continues into my storage room, and got a door to my kitchen.
My storage room, which of course got automatic sorting, so I just drop my stuff in the corner (which you can barely see to the right) and it gets put into the right places.
The stairs up to my magic room. Btw, I have placed Warden Stones instead of having door, which is nice when you get some rubberbanding.
This is my enchanting room, upstairs (using the levetator) is my potion room, which is just a room filled with shelves and potions

.
And of course there HAD to be a secret door/bookshelf entrance to my Thaumcraft room.
Downstairs, connected to my entrance room and my storage room, is my kitchen with it's storage.
And my machine room, don't have many machines yet, only my automatic power plant. There is more pictures regarding my
automatic power plant here.
And that's pretty much it. Also got a spawner room below, but it's not really finished, although its working. Want to use computer craft to control the turtles, instead having to manually restarting them.
