In my world, you can refer to the following for how to build a carved castle in my world:
First dig a 6*6 foundation, and then expand it downward by 4 blocks, so that the overall depth is 5 blocks.
After completion, expand this wall 5 blocks inward, leaving a layer of soil on the top.
Then come over here and build a ladder. You can mix cobblestone and stone bricks to build it, so that it reaches the bottom gently.
Then use logs to build two pillars on both sides, and then replace the mud blocks on both sides.
Dig a 2*3 area here from the stairs, and dig two 3*3 spaces on the side, two spaces apart.
Then put a stone staircase on the left and right sides of the top, and the same thing on the other side.
Then replace all the mud blocks with cobblestone, cracked stone bricks and stone blocks, and surround the top edge with stairs.
A row of spruce stairs is placed on both sides, and spruce logs are placed on the left and right of the main entrance.
Cover each side with a trap door, lay a row of spruce logs across it, and then decorate it with buttons and trap doors, and do the same on the other side.
Use stairs and stones to build a chimney here, and finally put in a campfire and a trap door.
The back is connected with logs and the bottom is connected with stones.
Place a row of stairs on each side and two rows of inverted stairs in the middle.
Use a fence and gate as well as a campfire and trap door to build a shelter at the door, and surround it with stone stairs inside.
Put the trapdoor and boxes here, replace the stairs with stones on the bottom sides, and hang lights.
Place three stairs here, then use a trapdoor to extend to the opposite side.
Add wooden barrels in the middle and connect them with wooden boards. Place two spruce logs at the bottom here, and replace the inner blocks with barrels.
Dig out the two bottom blocks and place the glowstone and flag on them.
Place two small beds, with carpets at the end of the bed and some candles at the head of the bed for lighting.
The area here can be placed with workbenches, chests and armor stands, and cauldrons and furnaces can be placed next to it.
Then press the fence gate at the door, and the entire carved castle is completed.
