You can't just combine any room willy-nilly! Focus on your basics: Power, Water, and Food production rooms like to stick together. Also, it's a game-changer when you upgrade them uniformly for mega efficiency.
Only production and storage rooms. Training rooms? Nope. Can't combine those.
Pretty much any resource-producing room or storage room can be combined. Just drag and drop another room of the same type next to it, and bam, you've got a bigger, better room. Keep those levels the same, though!
