I spent around 30 - 40 hours building this on the Vita. 8 walls with 2 different design patterns. 13 floors (each floor is 5 blocks in height) not counting the massive meeting room above. It still need lots of work on the outside walls decorations as well as interiors. This is y first creative mode project, I'm planning to expand into the whole city of Akiba next in the same map.
