Materials Prison Architect Guide
Last update: 25 May 2016
In the materials in the lower menu (screen above) there are two types of elements: walls and materials placed on the floor/ground. Both can get dirty, but it doesn't influence the gameplay in any way. In order to clean a dirty wall or floor, you have to use the Janitor or have the prisoners clean the prison (see: Deployment and Bureaucracy).
Walls are an important element, as they limit the freedom of prisoners. If you don't lock them in a specially prepared cell (with no holes and locked using a special Jail Door), they will quickly escape.
Walls also come useful when you want to separate given rooms, however - what's quite curious - they aren't needed in all cases. As you can see in the above screenshot, you can create cells (and all kinds of different rooms) without walls, as long as you create them inside a separate building. Such a solution is very economical, however it looks really stupid.
Walls can be destroyed by Workmen when you wish (demolish walls) or angry prisoners during riots. In the second case, you have to make sure no one escapes the prison, which can be done by building a free fence around the main building.
Below you can find a list of various types of walls. It's not really long, but it will probably grow with upcoming patches.
Icon | Name | Cost | Possible location | Description |
 | Concrete Wall | 50$ | Anywhere | A thick, stiff and exceptionally ugly wall. Their colour is the only difference from its brick counterpart. |
 | Brick Wall | 50$ | Anywhere | An universal type of walls. |
 | Fence | 0$ | Outside | Fences are completely free, so they're very handy for surrounding the whole area of the prison. |
Floors, unlike walls, serve mainly a decorative role. They can either increase or lower walk speed, but it doesn't really matter that much as most characters will move with a speed appropriate to a given task. Note that the default speed in rooms is High (concrete floor).
Icon | Name | Cost | Possible location | Walk speed | Description |
 | Dirt | 0$ | Outside | Slow | Regular dirt found outside you prison. You can get rid of unwanted bushes using it. |
 | Paving Stone | 10$ | Outside | Fast | Allows characters to move fast outside of the prison and looks quite aesthetically. |
 | Grass | 5$ | Outside | Slow | The only one requiring a gardener. |
 | Gravel | 10$ | Outside | Slow | Not very appealing kind of floor which also slows down. |
 | Road | 10$ | Outside | Normal | Anaesthetics and not very useful kind of floor. No one stick to it anyway. |
 | Stone | 10$ | Outside | Normal | A quite nice way to finish your prison, especially when placed by the walls. |
 | Concrete Tiles | 10$ | Anywhere | Fast | A universal and useful floor, unfortunately not very appealing. |
 | Concrete Floor | 10$ | Inside | Fast | A default type of floor inside buildings, received together with the foundations. |
 | Wooden Floor | 50$ | Inside | Normal | A very expensive, but decorative kind of floor. |
 | Ceramic Floor | 50$ | Inside | Normal | A very expensive, yet quite nice kind of floor. |
 | Mosaic Floor | 10$ | Inside | Fast | A nice, cheap and "fast" type of floor. Fits pretty much anywhere. |
 | Metal Floor | 10$ | Inside | Fast | A really ugly type of floor, yet fast at the same time. You're better off sticking with the concrete floor. |
 | Marble Tiles | 10$ | Inside | Normal | A luxurious and aesthetic floor at a reasonable price. Using it, you can turn your prison into a Greek temple! |
 | White Tiles | 10$ | Inside | Normal | Looks good in the doctor room and the morgue. |
 | Fancy Tiles | 10$ | Inside | Normal | A very nice and cheap floor. |
