I know a foolproof way to make a bad house in minecraft look nice: Step one- build it high up, floating, on a cliff, on stilts, I don't care. Step two- section off space for bedrooms, storage rooms, a kitchen, a useless bathroom, whatever. Step three- add as many decorations as you can. If the floor is made of dirt, plant flowers. Hang pictures on the walls, add paintings, flowerpots, banners, tie iron golems to the fence. Ta-da! Enjoy your lovely house!
Remember when I said that I love houses? Well I love them so much that I build my own on the Sims game. Throughout my childhood, I played this game with my sister building houses and since then, I have not stopped. I have created a ton of houses recently and I hope that one day that this can turn into reality.
