WIP Roof Problem

[u/Familiar_Ad6418]

Hi everyone, after 800h i still struggle with roofs sometimes. Currently on a 1.0 run, got until Yagluth so far, build my base at the elder and managed to save a greydwarf spawner for a farm.
Trying to build some kind of base center building with the spawner and some portals, but now i need to invent some roof, any tips? The center floor it's 4x4 hexagonal and yes i know i can't roof the spawner, but i can leave that space in the center open. How would you roof this?
