If you can get everyone to cooperate, then sure, go for it. The more obsidian we have the better.

Are you gonna try the new design in creative? And yeah, we can probably get that much obsidian pretty quickly because I know we already have quite a lot (possibly enough lol) and Kyle, Firo, and I will spend a lot of time mining.

Also, do the floors in-between necessarily have to be obsidian?

I'm doing it in single-player for now as the different designs I'm trying out are very very alpha.

No they can be whatever the owner of the floor chooses

And what of the player living under that owner? Do they just have to deal with having random blocks as the ceiling?

Oh ;_; we can make one block for ceilings for each player, so their ceiling is not the next persons floor, but then the the entire base has to become 17 blocks higher.

Unless people's rooms end up being 3 blocks tall

Which is why I'm sort of against the whole vertical design. I'm working on a sort of a cube complex design, I'll post pics in a bit.

Maybe instead of all one tall tower, a squatter square unit of the same type of tower, but divided into sections and put side by side instead of a single tower?

Mhmm. I was also thinking about a rectangular/square building with one floor for each section. IE. One for rooms, machines, farms, etc.

Ohh so all our rooms are on one floor...

It'd make for easier access. I'm not sure though, still in the very early stages. :P

So far I've fit everything into 7 stories.

Ah nice!
