A glass dome roof? Munaus, that's exactly what I did with my castles in 1.8.1 Vanilla.
But yeah, I also planned building a huge factory with a 5x5 chunk x 40 underground under my house, also finding out that it'll be very useless.
Now I'm only going to build a house and factory with marble only in a 2x2 tower above ground. Microblocks are pretty nice for building I gotta say.
A small tip is to make cubes of 8 as each room to see how you can use that space for something, maybe if you need more space or not.
