What happens when you run out of space but need to build something? For example, I need 2 quarries and only have 1, but I have no space in my kingdom to build anything else. Can I destroy an already existing structure to make room and how?
If you need more space to build buy store packs and gem research and troops. Clear more land with your OP massive force and boom your a boss!!!
You should also try to plan out what you build. Don't build too many of the buildings you don't think you'll need. Look at the descriptions of the buildings too and see what type of build type you will be going for in the long run. Total Lands End Game = 64 Quarry - rss max 7 Farm - rss max 7 Study- Support - max 10 Barracks - Support - max 10 Treasury - Support - max 10 Embassy- Support - max 10 Ward- Support - max 10 Dragon Alter- Support - max 10 If you look at the numbers, you'll see that there will have to be some buildings you don't build the max of there are only 64 spaces, but you have the possibility to build 74 buildings, so you'll have to decide what 10 buildings not to build...Pay attention to what they do and decide what you really need. You're also limited by the strength of the monsters you can kill. If you can't hit with a high enough army strength, you'll have to wait to clear some lands. So you won't have 64 spaces right out the door. It all depends on how well you can clear monsters in your city. There are many guides, so try checking some out to see other people's suggestions, but make sure you build to your play style, not theirs. There are many guides, and this is one of the many KoH Guide (For New Players ) <==Link At the top, there's more info on what I was talking about.
One suggestion is till u hit hugger the just build the bare minimum farms and mines. Build as many study, wards, and barracks these 3 give u immediate boost as they help in reducing times for research, training and hospital cap. Next build dragon altars these funny folks boost ur experience ur dragons gain. So having higher levels of these are always best. Last but not least embassy. These will allow u to get more allies that will boost ur overall attack strength when u r marching also they increase the clan slots u have allowing u to hoard more boxes.
