I've been using clip through for ages.

The new black marble columns can clip so that wood iron beams are at their centre, I'm currently building a large iron reinforced black marble structure on columns over my dock. First floor has alternating \ and / windows meeting in the middle with diamonds (sadly bats can get through these diamonds).

One long wall has a dvergr wall display of my weapons and tools, so I can pick and choose load out with quick keys and e. The room is big enough to support two hearths with a fake chimney, just tidying the smoke away visually. Other long wall has chests for food mats and a bank of five ovens - with dvergr wall and crystal over them to divert smoke out of the existing windows, but still allow light in.

Lighting was still an issue however. So I used darkwood beams between columns one metre down from the ceiling to place rows of wisp torches clipped into the ceiling, and crystal over the stems to help pick up the light and hide the stems. It creates a surprising amount of ambient light considering the light source itself should be blocked. It also gets light up through the floor into the next floor.

Overall it's an ugly cube in the sky, but it'll be large and practical and difficult for raids to attack.

My chickens have already survived raids in their black metal barn, though the seekers were curious. My other lot of chickens in the make shift semi-outside area were slaughtered by bats 😂.
