Here are some examples of things I've done using either cobble or smooth. I used single player commands to light up pictures from single player taken during night so you can see.
In this image, you can see another project in the background, out of smooth stone. It is not near enough to completion for me to post a screenshot of. This fortress isn't complete either, but it's close enough to post images of.
More images of it:
Main room. I haven't really furnished this fortress yet... The rest is just hallways and empty rooms, other than one room that IS in use, but it's really basic - three beds (because I could), workbench, 1-3 furnaces (forget how many). It also contains a small pool of water from which fish can be caught. The basement contains a minecart track and a darkroom trap, and one room featuring three walls of smooth stone (one with a window out into the hallway in it, and the remaining wall 100% furnaces.
Now for another structure. This one was built by me and another person on SMP.
This is an ancient church that was built for later use as a dungeon for players to go explore and get rewards from.
The dungeon area itself is behind a secret door. Also, the other guy did a really good job with trees around it. On an in-game map, it appears as a green blob, making one think it is a really lush forest through the map.
This is my main base in single player. The object of interest here is the smooth stone wall. After building this, I had quite the shortage of cobblestone up until I started a mine (whereas before I would get everything from cave dives or base digging).
In case anyone has questions about the textures in these images:
- Why is the grass/leaf texture from alpha?
I didn't like the biome color shading so I made a custom texture pack disabling it. Wildgrass was kind of difficult...
- Why is the cobblestone texture the old one instead of the new one from 1.7?
I didn't like the mixing of the new texture with mossy cobblestone. I'm not going to give this new texture a chance until mossy cobblestone is also updated.
Please don't build anything directly out of cobble...You can smelt 8 stacks of cobble into vastly better looking smooth stone with just one stack of coal. Or make half blocks for free.Buildings made out of cobble are pretty much the most efficient way to repel people from admiring your work in Minecraft. (it can be okay as an accent to make it look like the smooth stone has worn away in places, or for recessed portions of walls for variety in MODERATION, but if you plan on doing that, always experiment first with a small section to see how it looks).
Texture packs can change the texture for cobblestone to look better. Bricks>a bunch of rocks glued together.
