Hey guys, here's the mansion that I built in Creative for my Survival world. It was built on an unexplored Survival Map, so you can start a new game right there.
The house has three floors, you can also make a basement if you want to. The main hall takes up two stories of the central building, on the third floor there is a big living room with a billiard table and a piano. The three bedrooms and a pet room are located on the right side of the house. And on the left side there is a functional kitchen on the 1st floor with a separate storage, working room and a trophy room on the 2nd floor and a big storage on the 3rd. There is more that I forgot to mention, so you will see it yourself. The mansion is completely lit up inside, so you don't have to worry about monsters spawning. But they can still spawn outside, so be aware.
Have fun!
