This tower was built in 4 days, there is some construction going on inside for decorations. I am thinking of using this as a city center where newcomers can gather supplies: wood, wheat, sugarcane, melons, pumpkins, or to use as a gathering area: spleef arena currently 250 blocks up, with diving boards and lounge at top. There are free utilities inside, enchanting table with 30 bookcase cap, nether portal, and nearby a wool farm that has all 16 colors of sheep seperated into individual pens for easy shearing, and a skeleton spawner exp farm.
If anyone wants to move in simply tell me over forums and you may choose an already built room on the first two floors or build your own room inside, or construct around or near the center on the water or on the nearby land.
There is also room inside the small walls nearby for several houses to be built.
