The outside of my house. It's built on a sandy island, just a short swim away from my spawn point.
This is the main room. It has access to the roof, a mine shaft, and my farm. Also, it has my back door which leads to my trees that I planted, as well as a tundra biome not far away.
Here is my farm, which uses the irrigation as pathways, and uses some clean stone as spots to place torches.
The storage room... not much storage going on here yet. Eventually, once I find obsidian, it will also be home to a portal. For some reason, I've found several diamond deposits through my mining but no lava at all.
My rooftop garden! From here, I can shoot mobs that end up on my island (it also has access to the roof of the lower rooms of the building, this is several blocks higher because I put water here).
The platform in the sea, which I can go to at any time and kill mobs from up there as well.
Again, the platform. Once, as I was climbing up the ladder to this, I was killed by a creeper explosion. I quickly ran back to the spot to gather my items and a second creeper turned out to be up there and destroyed a lot of the items I dropped... not fun.
