Building a villa on top of a mountain near my spawn. It's nearing completion; it just needs the library/lounge and sloped roofing put on and the majority of the structure will be done.
Currently complete;
2F -Bedroom, small garden
1F - Main hall, Wheat farm, cobblestone generator
G - Main hall, Workshop, Primary storage, Dining room, Kitchen
B1 - Secondary storage
Also set up a water elevator going into the mountain to reach what is the front door quickly from my spawn, and a big 15-by-9 shaft a little way into the surrounding desert that drops straight down to bedrock level that I origonally made to collect a lot of cobblestone but have now converted it into a strip mine.
Other things on the adgenda;
-Turning the hillside behind the villa into a huge garden/dock area.
-Building an underground minecart transportation system connected to the water elevator for quick travel to any other places I venture to.
