What architectural change is NOT recommended to decrease prison violence?

The recommended approach to decrease prison violence often involves creating environments that enhance control and visibility within the facility. Large open yards, while they may provide recreational space for inmates, can also increase opportunities for conflict and violence due to the lack of surveillance and management.

In contrast, architectural features such as clear sight lines, small housing units, and security corridors are designed to promote safety and reduce violence. Clear sight lines allow staff to observe activities throughout the prison, thereby deterring potential violent behavior. Small housing units can reduce tension among inmates by limiting the number of individuals in a given area, and security corridors help ensure the protection of staff and inmates while providing controlled access to different sections of the facility.

Therefore, while large open yards might serve a recreational purpose, they are not conducive to reducing violence and are, thus, not recommended in the design of safer prison environments.
