Share your build mode cheats or tricks

Here's a picture where I used diagonal flooring, on a roof, but well, the result is mostly the same.


While I was looking for the above images, I also ran into a few skylights - made with a glass roof piece in between opaque roof pieces. I often use this technique to add more natural light to rooms.

I even wrote a tutorial on how to make them, back when we first got the glass roofs.

I do feel I was more creative with build mode back when it was more limited.
I once built this neat little greenhouse before we had adjustable foundations and glass roofs. It was a bit annoying to play in, but at least it was a greenhouse.
