An author architect brings a design philosophy to a project — a way of resolving structural, material, and spatial questions that is consistent across projects but produces different outcomes in different conditions. In Mexico City, where the combination of seismic risk, volcanic geology, altitude, and urban density creates a specific design context, author architecture is not a style claim. It is a practice commitment.
In MÉTODO, concrete interiors in CDMX residences are the result of that commitment. The material is not a trend; it is our primary design medium, and Mexico City is where we have built the deepest knowledge of how to use it.
What Author Architecture Means in a Mexico City Concrete Interior
The term casa de autor — author house — describes a residence where every design decision responds to the specific site and client, guided by a consistent set of architectural principles rather than style references. In CDMX's residential market, this distinguishes MÉTODO from two other categories of design service:
Developer residential design: Optimizes for cost, unit density, and fast delivery. Concrete appears as structure, concealed behind gypsum board and tile. The interior has no architectural argument — it is a collection of finish materials.
Interior design over developer construction: Applies curated finishes and furniture to a generic floor plate. Concrete may appear as micro-cement on floors or as an exposed detail, but the structural logic was never designed for it.
Author architecture in concrete: The structural concrete walls are both the building's resistance system and its interior surfaces. Their placement responds to seismic requirements, solar orientation, and spatial sequence. The formwork pattern is designed. The openings are proportioned for the specific quality of light they deliver. The result cannot be transferred to a different site or client.
The process before the style. In CDMX, the design process for a concrete author residence begins with soil investigation, seismic classification, and solar study before any spatial idea is drawn.
Mexico City's Specific Conditions for Concrete Interior Design
Seismic Zone D. Mexico City is in the highest seismic hazard zone in the Mexican code. Structural concrete walls for residential use must satisfy ductile detailing requirements: specific reinforcement ratios, transverse hoops at confined boundary elements, and minimum wall thickness of 150 mm for non-special elements, 200 mm minimum for special structural walls.
These requirements produce walls with a specific scale and material presence. When exposed as interior finish, a 200 mm concrete structural wall with its confined boundary elements reads as architecture — it communicates what it does. This is different from a decorative concrete panel that has no structural role.
Variable soil conditions. CDMX's subsoil ranges from competent volcanic rock in Pedregal and southern Coyoacán to highly compressible lakebed sediment in Iztapalapa and eastern delegaciones. Foundation design varies dramatically between these zones. In competent-rock zones, shallow foundations and concrete slabs perform well. In lakebed zones, deep piles and compensated foundations are required, and differential settlement is an ongoing condition that structural details must accommodate.
Altitude and UV. At 2,240 m, UV intensity in CDMX is significant — comparable to Denver at 1,600 m. Interior concrete finishes are not affected by UV, but exterior concrete details, sealers, and any wood or polymer elements at exposed conditions degrade more quickly than at sea level.
Temperate climate. CDMX's year-round climate is mild — average highs of 23 degrees Celsius in summer, 20 degrees Celsius in winter, with cool evenings year-round. Concrete's thermal mass is an advantage: it moderates the diurnal swing without requiring mechanical conditioning in most months.
How We Design Concrete Interiors in CDMX Residences
The design process for a Mexico City concrete interior begins in schematic design and closes with construction administration. The sequence is not negotiable.
Solar study. CDMX's latitude (19 degrees North) means the sun tracks north of the zenith in summer. North-facing rooms in CDMX receive direct sun in summer and are shaded in winter — the opposite of mid-latitude behavior. This affects which rooms should face south (winter light, winter solar gain) versus north (summer shade, diffuse light).
Structural wall placement. In a seismic zone, structural walls must provide lateral resistance in two orthogonal directions. Their placement is coordinated with the structural engineer in design development. In MÉTODO, we treat this coordination as an opportunity — structural walls positioned for seismic performance are often the same walls that define spatial boundaries in the interior.
Formwork design. Interior concrete walls in a CDMX residence that will remain exposed are specified as architectural concrete with controlled formwork. Tie rod spacing and diameter are detailed in the drawings. Pour height is specified to avoid surface segregation. The contractor who wins the concrete work must demonstrate prior experience with architectural concrete surfaces.
Light strategy. CDMX's diffuse-light conditions on cloudy rainy-season days and intense-light conditions on dry-season days require apertures that perform in both. We typically design north-facing apertures for consistent diffuse daylight and south-facing apertures with shading for direct winter gain.
Material Palette in a CDMX Concrete Author Residence
In MÉTODO's Mexico City residential work, concrete appears alongside:
- Cantera or chiluca stone at floor paving and exterior site walls. These are local volcanic stones that connect the residence to the geology of the altiplano.
- Dark hardwood — typically tzalam or parota — at ceiling structure, door frames, and cabinetry. The contrast with concrete is warm and immediate.
- Unpainted lime plaster in bedrooms and secondary spaces where concrete surface quality may not meet interior standards or where acoustic softening is desired.
- Steel at structural connections and window frames. Expressed, not concealed.
Piedra, madera y concreto: materiales que envejecen con dignidad. In Mexico City, these materials also age with the specific character of the altitude and the seasons — dry season dust, rainy season moisture, volcanic light.
Próximos pasos
A CDMX concrete author residence begins with a site visit and a conversation about the specific conditions — neighborhood, soil zone, orientation, and program. Not a portfolio review, not a style discussion. The material and the method are already established.
