Look at other minecraft mansions. There are lots of great mansions already existing which you can find images or video tours of readily online. Look at your favorite structures from familiar TV shows, movies, and books. Maybe you want to make Hogwarts castle or Superman’s fortress. Look at house plan websites. There are many websites online where people go to buy plans for actual houses. You can use these as inspiration, as they will show you the layout of the house, as well as how the outside looks. Such preview images should always be free.
You can include basic rooms like kitchens, bathrooms, bedrooms, and dens. You can also include silly rooms like a dungeon, art gallery, trophy room, or chicken storage.
You can use free services like MineDraft to draw out your plans. If you do not have or want access to tools like this, you can use paper and color-coded color pencils to help you plan.
You can use it as a reward for finishing homework or household chores. 1 hour of play = 3 hours of work, for example.
Create windows and doors by leaving gaps as you go. This requires more planning but is easier than having to remove all of those materials later.
This is a good time to get inspiration from other Minecraft homes. However, make sure you add your own style, and not just copy every detail from something else.
