I'v desided to build a massive desert caslte  I just built 1 wall which took 6 minecraft days (2.1 hours)
i plan on building the whole desert im using into a town made out of standstone  and other materials.
if you think i should build something interesting like a sewage system i will think about.
also this is a singleplayer project and will  be doing this all on my own. 
once this project is finished i will upload it for all to use! 

p.s i am only  using creative mode no world edit or anything fancy.
