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.

Concrete is often seen as the material of modernity, defined by its structural strength, raw finish, and unmistakable gray tone. It became the default palette of 20th-century architecture, a symbol of functionality and permanence. Yet, concrete is not bound to this chromatic identity. Its color is a byproduct of the cement, aggregates, and chemical composition used in its mix, and it can be intentionally altered through pigmentation. Among the many hues explored, red stands out — not only for its visual intensity, but for its ability to root buildings in place, evoke cultural references, and imbue architecture with a material presence that feels both elemental and expressive.

Pigmenting concrete involves the addition of mineral-based colorants — usually iron oxides — during the mixing process. Unlike paints or coatings applied to the surface, these pigments are integrated directly into the concrete mass, ensuring the color permeates the material and remains stable over time. Red pigments in particular are often derived from iron oxide (Fe₂O₃), a naturally occurring compound found in clay, hematite, and other iron-rich minerals. Their deep, earthy hue connects contemporary construction with ancient techniques — from Roman pozzolana mortars to the red earth buildings of West Africa and South America.

Thatching is a traditional building technique that has been reinterpreted in different ways in contemporary projects, allowing its value to continue to endure over time. As well as being a culturally and historically valuable technique, given its presence in humanity for centuries, it also has a number of other constructive advantages, such as its great environmental value, as it is an accessible renewable material.

The technique consists of grouping, intertwining, and overlapping dry vegetation, creating light surfaces with excellent thermal and sound insulation and which are cheap and relatively simple to build. In addition, flexibility is one of the technique's most prominent features, and it is particularly popular in roofing applications.
