I'm making my main house into a castle, I already have the main room with lots of art pieces, a throne and some cool candles, a little bath area, the princess themed bedroom upstairs and a library
I'm having a hard time with my left side room and my downstairs, does anyone have any ideas what I should make those two rooms? <3
Ahh all these ideas are so good! I really like the idea of the basement dungeon, and the dining room. Getting a table to look big enough for that might be difficult though, since the biggest tables are 2x2.
I'm going for a medieval themed town myself and have a castle home so I might be able to offer a bit of insight. The dungeon in the basement is certainly a must, for mine I made an undead dragon out of the dinosaur fossils T-rex skull, apato torso, ankylo tail, and a pair of ptera wings with a fire bar in front to simulate fire-breathing. I put egg lamps on one side and two creepy skeletons with a treasure chest on the other side. You can use my idea if you want, the ptera wings stick out a little but the rest of the fossils fit together rather well, I specifically chose fossils that looked the right height to connect to one another so I don't think you could form a better dracolich.
On my left room I have an armory with mannequins in various armored outfits, swords, a cannon, my gold axe and toy hammer on the table, things like that.
My right room has a royal garden/courtyard with various plants and a couple of outdoor baths in the middle with a merlion behind one to make it look like a fountain.
You could also make a church or something with stained glass windows, I haven't done it myself because I ran out of rooms but churches tend to be pretty medieval if you want to go that route.
