[1.9.4] Generate massive structures

[Guest]

I want to generate absolutely massive structures with a size of about 10*10 chunks or more. An example of what one of the structures will be representing: http://rainbow6.ubi.com/siege/de-de/game-info/map/consulate.aspx. The structure has to only exist once in a world and be at the spawn point. The structure needs to contain blocks with tile entities which need to have additional data applied to them. Can I do this with a normal structure generator or whatever they are called or do I need to write my own world type with a special ChunkProvider and BiomeProvider?

How can I be safe that everything is in the chunk is should be in?

Ok, makes sense. I'll try that tomorrow.
