My main base at Dr. Who Online -
On the left is The World's Inn, a simple hotel for some of our players to hang out at on the Eastern edge of the world.
In the center is my base itself, a series of spheres and half-spheres. Most of my living is done in the bottom sphere, but I have a workshop at the base of it. This was built on a little sliver of island, expanded somewhat by lava pours on water.
Off to the right, you can see my piers, where I host my tree and mob farm.
Taken from another player's build in the middle of the sea. You can see there's a bridge behind everything, it runs to the only desert several chunks away. The bridge lies on the eastern edge of this world, just waiting for expansion.
A side-view of my spheres, I may stack more on. The half-spheres will be farms but you can see my tardis (dr. who server!) parked on the half-sphere on the right.
