all directions are to ba taken as if you are looking outside from the tower entrance.
1) I expanded the mines ( small wooden door on the left). I dug a couple more tunnels and put some stairs on an already existing tunnel. I found some more caves. One of which is marked with a sign, since it is hard to find (you have to swim upward in a river to enter. I didn't do much, all I needed was cobble.
2)The treefarm, on the right. I wanted to have a building to farm trees. I made the errors of using it before it was completed. Apparently, I planted trees in a good way to make them grow large. Since I didn't bother cutting the big trees, in a couple harvests nature reclaimed that spot. I could have just cut the huge trees that spawned, but I actually like it more that way.I would be happy if the trees were to stay, without being cut. But if the area is needed, I may not oppose burning them.
3) the storage, on the right. it has a public building and some underground chambers meant for personal storage. I posted more about it in a previous post, with pictures. While I only had time to dig 4 personal storage room, it can be expanded as need arises.
4)right in front of the tower, the gate room, the last thing I did before uploading the save. It is a room meant to host the future gate to hell, should the saves work well with the update. At the moment instead of the obsidian gate there is a cobblestone gate. removal of it for gate building purposes should not cause flooding.
The sand structure outside is NOT decorative. if you delete the only torch attached to the wall, the lowest one, the whole structure will fall, sealing the room. If monsters from hell chase you, this can be a way to stop them or at least buy time.
Feel free to change this building or expand it in the future, especially for safety purposes. Eventually, I wouldn't mind having the main gate in a stargate-like room.
JHLL, the wool is in my storage room. feel free to use it if you are doing the space shuttle.
