The North Hub, IMO, looks pretty good structurally. However, the amount of exposed netherrack was just bumming me out. While I was tearing out a corner to put in the furnace system, I got inspired on how to make it look better. The sandstone up above the furnaces is what I did. I have a plan or two for continuing things on the ceiling as well.

Whatcha think?

Mostly finished results. The first one shows the enchanting station, moved back into the wall a bit. The second one shows the ceiling design. The third is the public chests.

I do need a bit of glowstone still if anyone has some spares. There are some 2×2 holes in the ceiling design where they go. I think I need 18 more to complete it.

I enjoy the look, very good job. Have you considered that this particular hub does have a darker theme to it, and ways to light it up more?
