Minecraft wiki entry for Adding_beauty_to_constructions, associated text: Under certain circumstances, a glass floor can look excellent (for example, as a see-through bridge over a ravine or river, or a room where the ceiling and floor are identical), but in most builds, glass is not the material to use. It's recommended that the floor should not be made out of grass or dirt blocks, as they are better suited to outdoor landscaping. It is better to use a floor made of wood planks or stone (including its variants such as sandstone). Smooth stone looks good as tiles, as well as polished granite, diorite, and andesite. Wool is decorative, but again, keep it away from fire hazards. Use concrete as a fireproof alternative. Carpet is a much better alternative to wool, due to its being cheaper. Also, you can put mycelium under carpet to make the carpet look mystical or sparkly. To add a touch of oldness to your floor, for example, if it is made out of stone bricks, use some regular stone bricks (the more, the less abandoned it looks), some cracked stone bricks, and some cobblestone/gravel as very cracked stone bricks. Variation of blocks in your floor adds detail to it, you can also use the mossy variant of stone bricks/cobblestone. To make the floor look worn down/heavily trampled use stone and/or light gray wool. Sandstone floors can have cracks if a sandstone stair block is placed in an upside down position. For a tiled effect, try dark prismarine, which look good in environments such as kitchens, bathrooms and swimming pools. Terracotta and glazed terracotta blocks can form a satisfying, space age floor. Bone blocks can look good when placed sideways to make a smooth, white, lined floor. Wood or stripped wood floors can also look good.
