Colombia is experiencing a transition process that began in late 2016 with the signing of the peace agreement that ended an armed conflict of more than 60 years. As part of this process, architectural projects aiming at the individual and collective reparation of victims, the reincorporation of ex-guerrillas, and the well-being of local communities have been produced. This article presents architectural design parameters elaborated through field findings and the review of design practices related to the transition. Those parameters will allow the review of architectural projects generated in this scenario and the basis for the generation of design guidelines for different contexts. The study allows concluding the emerging responsibility of architecture in the transitional process of peace building in Colombia and the need to design tools for its effective contribution to this process.
