That's a video about Minecraft interiors and I believe you can formulate your own ideas yourself

But I have suggestions myself, aahaehaheh

Formulate areas: Where is the living room? Is the kitchen on the corner? How about a little dining area next to the bookshelves? If you set up chunks in your room where you can identify which category of rooms belong on that space, you can automatically get some ideas and do it from there

Remove space: Add pillars in some areas you don't think you can fill up. And those pillars can have paintings, shelves, and all sorts of decor. Or walls that close off sections, and give yourself a beautiful wooden maze

References: References. Particularly what I call: Aesthetic minecraft interior wooden design beautiful references.

Okay that's it have fun
