Mauricio Ceballos × Architects (MCxA) is a Mexico City–based global design studio shaping a collaborative, research‑driven architecture that responds to context, nature, and human experience.

Founded on a belief that great design emerges through diverse voices and systematic rigor, MCxA has contributed to landmark works from the New Mexico City Airport to cultural and residential projects worldwide.

Their created Casa Santuario earned a Future House Award, and the Jesús & Ulrike Retirement Residence was honored with a Green Good Design Award —testaments to the firm’s innovative, sustainable architectural vision.

GDN: If you had to summarize MCxA’s philosophy in one sentence today, what would it be—and how has that sentence changed over time?

Mauricio Ceballos: Today, MCxA’s philosophy might be summarized as: “Architecture is a living system — one that must breathe with its landscape, serve its community, and endure across generations.”

In our earlier years, the focus was primarily on formal innovation and technical precision — how a building performs, how it responds to climate, how it is constructed. Over time, that sentence has grown more expansive.

We began to understand that a building is a relationship between people and place, between tradition and technology, between the immediate and the long-term. 

Our practice taught us that quality architecture is commitment to a way of living: off-grid water systems, passive solar design, and materials that age gracefully within their landscape.

The philosophy has matured from “design well” to “design responsibly” and now, increasingly, to “design with.” With the community, with the climate, with the memory of a place.

GDN: You describe sustainability as a holistic system — how do you integrate environmental, social, and cultural dimensions into a single architectural strategy?

Mauricio Ceballoss: For us, sustainability has never been reducible to energy metrics or green certifications. It is, at its core, a question of belonging — does this building belong to its landscape? Does it belong to the people who will inhabit it? Does it belong to the culture that shaped the place where it stands? 

Our process begins before the first sketch. We conduct site analyses — studying solar paths, prevailing winds, water cycles, and soil composition — but alongside these, we document local craft traditions, regional materials, and the social dynamics of the communities we work with. 

These layers inform one another: a rammed-earth wall is not just an environmental choice but a cultural statement; a shaded courtyard is not just a thermal strategy but a social invitation.

In practice, this means that environmental performance and cultural resonance are evaluated together, never in isolation.

A building that is thermally efficient but culturally alienating is, for us, an incomplete solution.

We strive for architecture where the three dimensions — environmental, social, and cultural — are so interwoven that separating them becomes impossible.

GDN: You use advanced analytical tools to study comfort, energy, and daylight — how does this data influence design decisions without limiting creativity?

Mauricio Ceballos: Data collection and analysis is a creative catalyst. When we model daylight penetration or map thermal comfort zones, we are not narrowing the design; we are sharpening our understanding of what the building truly needs to be.

The key is knowing when to listen to the data and when to question it.

Early in the process, analytical tools help us identify the non-negotiables: the orientation that captures winter sun, the overhang depth that prevents summer overheating, the natural ventilation path that makes mechanical cooling unnecessary.

These become the armature around which creative decisions are made freely.

What we have found, consistently, is that the most elegant solutions emerge precisely at the intersection of rigorous analysis and intuitive design.

A roof that tilts to harvest rainwater and simultaneously frames a mountain view is not a compromise — it is architecture at its most resolved.

The data does not tell us what the building should look like; it tells us what it must do. How it does it remains entirely our domain.

GDN: In projects like Jesus & Ulrike Retirement Residence, how do you balance net-zero autonomy (off-grid water, solar) with practical longevity, like choosing concrete over rammed earth?

Mauricio Ceballos: This is one of the most honest tensions in contemporary sustainable architecture, and we do not pretend it has a single answer.

In the case of Casa Jesús y Ulrike, the decision to use concrete in certain structural elements — rather than rammed earth throughout — was the result of a careful dialogue between aspiration and responsibility. 

Rammed earth is a material we deeply respect: it is thermally massive, locally sourced, and carries an authenticity of place that no industrialized material can replicate.

However, in a residence designed for long-term habitation by clients on a site with specific seismic and moisture conditions, the structural reliability of reinforced concrete in key load-bearing elements was a choice made in service of the inhabitants, not in contradiction of our values.

Net-zero autonomy — the rainwater harvesting system, the solar array, the passive cooling strategies — was never compromised. 

What we calibrated was the material hierarchy: earth where it could perform optimally and age beautifully, concrete where it was structurally indispensable. Longevity is, in itself, a form of sustainability. 

GDN: Many of your projects emphasize local identity and craftsmanship — how do you avoid “globalized architecture”?

Mauricio Ceballos: By beginning every project with a question that has nothing to do with architecture: What does this place remember? Globalized architecture, in our view, is the product of designs that could have been built anywhere.

Avoiding it requires a genuine act of listening before any act of designing. 

We spend considerable time studying regional building traditions and analysing how vernacular architecture has responded to the same climatic and cultural conditions we face.

This does not mean reproducing the past. It means understanding why a particular roof pitch, a particular material, or a particular threshold configuration evolved the way it did — and then asking what that wisdom means for a building being designed today. 

In Mexico, this conversation is extraordinarily rich: pre-Hispanic spatial principles, colonial courtyard logic, and contemporary craftsmanship in wood, stone, and tile all offer languages that, when spoken with care, produce architecture that is unmistakably of its place. The result is never nostalgic. It is, we hope, deeply rooted.

GDN: Which global challenges do you feel architects must urgently address?

Mauricio Ceballos: Three come to mind immediately, and they are deeply interconnected. The first is the climate emergency — not as an abstraction, but as a practical imperative that must reshape how we orient, construct, and detail every building we design. Architecture is responsible for nearly 40% of global energy consumption; our discipline carries an enormous obligation. 

The second is the housing crisis, particularly in the Global South. Millions of people live in inadequate, unsafe conditions, and the architectural profession has too often positioned itself as a service for the privileged few. We need more architects willing to work at the scale of social urgency — designing with communities, not for them. 

The third is the erasure of cultural memory through built environments. As cities homogenize under the pressure of fast construction, entire ways of inhabiting the world are being lost.

We have a responsibility to resist this — not through historicism, but through a commitment to place, craft, and the specificity of human experience.

These three challenges — ecological, social, and cultural — are, in the end, one challenge: learning to build in a way that sustains life in all its dimensions.
