Stairs suitable for mining
Never again will you need to resort to using ugly Cobblestone stairs in your mine. If you don't want to smelt so many stairs, just use Polished Andesite; It looks almost the same. Or ask an admin to exchange it in return for taking appropriate fuel.
Giant Nether Temple
Or, if you have hours to spare and glorious diamonds to use, you could create a giant Nether Temple! Warning: I take no responsibility for your reaction when you need to move it
Stonewalled
Block off dangerous mine shafts in style with stone walls. Comes in a variety of non-flammable flavours.
Polished Granite Roads
These roads would work well in a village made from bricks and granite.
The best roads yet
Okay, maybe I'm being over-confident now. These roads do look nice!
Nether Temple
In less than five minutes, you can turn a boring old Nether Portal into a nice small Nether Temple. Just keep an escape handy on the inside if you don't have a door!
