Stone blocks

Stone blocks are produced by cutting rock chunks on a Stonecutter's table after researching Stonecutting. Colonist with 'crafting' enabled will perform this task, but performing it does not grant any skill progress. Stone blocks are always produced in batches of 20 per rock chunk. Blocks can also be salvaged by deconstructing abandoned structures.

Stone blocks can be used to build walls and doors, and lay fancy floors with faster walk speed and less ugliness penalty, as well as to build furniture and many production benches. It's also one of the prime materials for crafting sculptures.

Comparison table[edit]

Below is a list of material effects for stone blocks. When a stuffable item is created from a stone block, each of its base stats is multiplied by a factor for that stat belonging to the material used. Take "Hit Points" for example. For this stat, granite blocks have a factor of 1.7 and walls have a base stat of 300. Thus, the final "Hit Points" of a granite wall is: 1.7 × 300 = 510

This process is then repeated for each stat. The material's sharp damage factor is applied to the items base sharp damage, flammability factor to flammability etc.

Market value is the notable exception to this direct multiplicative relationship, but the value of a material does have a direct effect on that of the final product. See Market Value for details.

All stones blocks have the following modifiers in common:

Walls and Floors[edit]

As the table above shows, Marble is the only stone block with a Beauty Offset. This affects the beauty and impressiveness of rooms made from stone blocks, but the game only takes this into account for walls and not floors. Rooms made with marble walls are more beautiful and impressive than other stone walls, but the type of stone used for the floor makes no difference. Any type of stone floor will be equally more beautiful and impressive than dirt.


Spike traps made from stone blocks have different damage and hit points, based upon the type of stone used per the table above, but also different armor penetration. Granite is the most effective stone, sandstone least, and all other stone types are intermediate. Traps made from any stone will be much slower to build than traps made from non-stony materials. See Spike trap page for details.


Granite blocks.png

Blocks of solid granite. Granite is a very hard stone.

Granite is the strongest of all stone blocks and is best suited to build walls in the fighting area.

Limestone blocks.png

Blocks of solid limestone.

Besides being the second most durable stone type after granite, limestone blocks have no practical advantage over other stone blocks.

Marble blocks.png

Blocks of solid marble. Marble is a soft, beautiful stone, known for being easy to sculpt.

Of all stone block materials, marble has the highest Beauty factor and stands alone as the sole stone to have a beauty bonus, and so is best suited to create art for your base. It is also a close second in terms of market value per unit of work, after sandstone, so is well suited to craft items for sale in bulk.

Sandstone blocks.png

Blocks of solid sandstone. Sandstone is a relatively soft rock and chips easily.

Sandstone is the quickest stone type to work with, making it well suited for stone constructions that need to be built quickly. It also has the highest market value per unit of work so is the best stone type for crafting items for sale in bulk.

Slate blocks.png

Blocks of solid slate. A dull-looking rock that chips easily.

The only advantage of slate blocks is that they are the least heavy. If for some reason you need to carry stone blocks or chunks in a caravan in bulk, slate might be the best choice.
