This group is to upload the simply enormous amount of pictures, videos, news, articles, features and whole worlds that the Minecraft Community has.
All blocks harvested, smelted, crafted, and placed in survival; although some of the design-work was done on a creative world, then built in the survival map.
Despite how some would consider this a huge castle, it only reaches manor scale for me. Any castle I would build would have curtain walls at least 30 blocks tall by 4+ blocks thick. Although the structure built with netherbricks, the Golem Workshop (the closed gate will eventually lead to another circular structure built around the current one), probably bumps the whole affair up to near-castle levels of effort.
>100 chests (I love chests)
>9000 stone bricks
(Probably) >1000 netherbricks
Library with >140 bookshelves
I for one would love to see if anyone has anything even more impressive than this. Remember, you can design your structure in creative, but all the material-gathering and building has to be done in survival.
