Minecraft wiki entry for Adding_beauty_to_constructions, associated text: Keep lots of open spaces and do not use too many doors, so your house will look more than "Designer". Light rooms up with redstone lamps or sea lanterns and glowstone instead of torches to improve lighting, or add chandeliers for a classier look. Also you can put paintings or item frames on the walls that look empty. You can "hang up" a torch by placing a torch on a block, then an item frame on the same block, before finishing it up by placing a stone button, stone slab, or an anvil inside the item frame. (Note that this will not work in Bedrock Edition due to the fact that item frames are not entities in that version.) You can also keep cats and dogs in the building.
