In the architectural history of the Mexican territory, the built environment has functioned not merely as a human stage, but as a biological infrastructure designed to organize proximity between species. The resulting spatial logic is not a solo performance, but a negotiated coexistence between human and animal bodies. To examine this heritage today is to shift the analytical focus away from stylistic authorship and toward a more fundamental phenomenon: the persistence of spatial practices that emerged to sustain shared forms of life.
Many of the architectural features now interpreted as cultural or aesthetic markers — oversized thresholds, expansive patios, and durable surfaces — can be understood instead as material traces of an interspecies contract. For centuries, horses, mules, and livestock were not external to architecture but essential inhabitants whose physical presence shaped scale, circulation, and material choices. Their bodies left measurable imprints in space, from the height of entrances that accommodated mounted riders to paving systems designed to withstand hooves, friction, and biological wear. Nowhere was this contract more visible than at the ground level of the colonial house.
