The tambos are small buildings that function as social platforms in Peruvian rural areas to provide essential services to the entire vulnerable and dispersed rural population. The Peruvian government intends to implement more than a thousand new tambos in the national territory. However, this social infrastructure program faces heterogeneous conditions and demands according to Peru’s geographical and population complexity. This article proposes developing a systematic catalog of modular components as a design strategy for the architectural approach of future tambos. Georeferenced data and climate design guidelines were used to conduct this study. As a result, the systematic catalog synthesizes critical variables such as natural regions and programmatic requirements to generate diverse architectural configurations of the new tambos. Therefore, these future buildings would be optimally articulated in different areas of influence under a systematic vision of the Peruvian rural territory.
