Big castles require wood-iron framing.

Good to know, i was having trouble with expanding on a ruined tower and gave up on height because of it breaking all the time

Before I lost my world I had 4 floors, each 2 full size stone high. I pre-framed it all with iron wood beams first and then placed the stone to link to them. Then used darkwood for some of the roof and straw. I believe I could've gone 1 story higher if I wanted to farm more iron.
