Stone, wood, and concrete are materials that age with dignity. This is not a stylistic preference — it is a statement about how buildings perform over time. Composite materials, applied finishes, and imitation surfaces degrade in ways that are difficult to reverse. A chiluca stone wall, a tzalam wood ceiling, and an exposed concrete column improve with time: they patina, they show their history, they do not look like a new building that has gotten old.
In MÉTODO, the material palette is not chosen after the design — it is part of the design hypothesis from the beginning.
Stone in Mexican residential architecture
Mexico has an extraordinarily rich stone tradition. The central plateau sits on volcanic geology that has been quarried for construction for centuries. The major stones in use:
- Chiluca: A pale, fine-grained volcanic tuff quarried near Mexico City. Soft enough to carve, hard enough for walls and cladding. It registers shadow beautifully because its surface is slightly rough. It weathers to a warm grey-cream over time.
- Cantera: The broader family of volcanic ignimbrite quarried across Mexico (Guanajuato, Zacatecas, Oaxaca have distinct regional variants). Colors range from pink to grey to black. Traditional in colonial architecture; equally appropriate in contemporary work when used without applied ornamentation.
- Tezontle: Red volcanic scoria, porous and lightweight, excellent for thermal mass walls in highland climates. Its rough surface and warm color read differently from cut stone — more raw, more geological.
- Andesite and basalt: Dense igneous stones for floors, stairs, and exterior paving that requires abrasion resistance. Cold to the touch, which is an asset in warm climates.
The choice between these stones is driven by climate, structural requirement, and regional availability — not by catalog selection.
Wood: species, structure, and maintenance honesty
Wood in MÉTODO projects is always structural or clearly functional — ceiling beams, door and window frames, millwork, floor decking in covered outdoor areas. We do not apply wood veneer to surfaces that do not need it.
The species we specify for Mexican projects:
- Tzalam (Caribbean Walnut): Dense, dark-brown tropical hardwood, naturally insect and humidity resistant. Used for exterior woodwork, door and window frames, and exposed structural beams in covered areas.
- Parota (Guanacaste): Wide-grain, lighter tropical hardwood. Excellent for large-format millwork — kitchen countertops, dining tables, long wall panels — because of its naturally wide boards.
- Encino (Mexican Oak): Used for interior flooring and millwork where a harder, finer-grained surface is appropriate.
All exterior wood elements in MÉTODO projects are detailed with proper end-grain protection, adequate ventilation clearances, and documented maintenance intervals. Wood that is correctly detailed and maintained outlasts wood that is incorrectly detailed and replaced.
Concrete: structure made visible
Exposed concrete in MÉTODO projects is a decision about structure made visible. When we leave concrete exposed, we are saying: this is what the building is made of. The formwork texture, the tie holes, the cold joints between pours — these are not defects to be hidden. They are the record of how the building was made.
This requires precision in formwork design and execution. The formwork determines the surface. In Mexican construction practice, skilled formwork carpenters can produce consistent, tight-jointed surfaces that read as designed rather than as incidental. We specify the formwork system and the desired surface quality in the construction documents — not as a vague note but as a detailed specification with acceptable tolerance ranges.
For seismic zones like Mexico City, concrete frames are the standard structural system. Leaving them exposed is not a foreign idea — it is simply the decision not to cover what is already there.
Cross-border material coordination
For US-based clients building in Mexico who want to specify materials from both sides of the border, the practical approach:
- Mexican stone and concrete: Source locally. The quality is high, the labor tradition is deep, and import costs from the US would not be justified.
- Fixtures and hardware: US-sourced fixtures can be imported; budget import duties at 15 to 25 percent of declared value and two to four weeks for customs clearance.
- Wood: Mexican tropical hardwoods are superior to many US equivalents for the climate. If the client wants a specific US species, we evaluate it against local alternatives.

The material palette of a project is established during site analysis and schematic design — it should not be resolved in the construction documents phase when changing it is expensive.
