Exposed concrete and wood in a contemporary courtyard house are not a trend. They are a material hierarchy based on where density is needed and where warmth is needed. Concrete at the structure. Wood at the inhabitable surface. The courtyard connects both to light.
The Material Hierarchy: Why Concrete Anchors the Plan
In a courtyard house, the structural walls that enclose the patio are the primary thermal mass elements. These walls receive solar radiation reflected and diffused from the courtyard floor, absorb it during the day, and radiate it into the adjacent rooms at night. For this to function, the walls need real mass — not the simulation of mass provided by a thin concrete veneer over a stud frame.
In MÉTODO projects, exposed cast-in-place concrete walls are used at positions where structural and thermal function coincide: the party walls of the courtyard enclosure, the floor slabs at grade, and the load-bearing elements of the roof. These are concrete because concrete performs in those locations, not because it photographs well.
The mix design for interior exposed concrete differs from structural concrete. Water-to-cement ratios are lower, aggregate is selected for color consistency, and the pour sequence is planned to minimize cold joints at visible surfaces. The formwork material — plywood, steel, timber boards — determines the surface texture. In MÉTODO, formwork is specified as a design element, not as a contractor's choice.
Wood at the Human Scale
Wood enters the material palette at the surfaces that receive direct human contact and at the acoustic planes that need to absorb sound. In a concrete-dominant interior, all hard surfaces — floor, wall, ceiling — create a reverberation condition that is uncomfortable for daily occupation. Wood at the ceiling plane, at built-in joinery, and at door and window elements absorbs the mid-frequency sound that concrete reflects.
This is not decorative. It is acoustic design resolved in the finish schedule. Materialidad honesta extends to the acoustic performance of surfaces — a room that sounds harsh is not finished, regardless of its visual quality.
White oak, walnut, parota, and tzalam are the species we specify most frequently. They are dense enough to hold their form at door frames and window sills without deflection, and their grain and color stabilize over time rather than requiring periodic refinishing. A parota countertop at year fifteen is more beautiful than at year one. A painted surface at year fifteen requires work.
The Courtyard as the Light Source for Both Materials
The courtyard transforms how concrete and wood read inside the house. In a room that receives only north light through a street-facing window, concrete reads heavy and cold. In a room that opens to a courtyard — where light arrives from above, reflected off the patio floor, and scattered by planting — the same concrete reads luminous. The courtyard is the light source that makes the material palette work.
This is why the section is designed before the materials are specified. The section determines the height of the courtyard walls, the depth of the overhang, and the angle at which light enters each room at each hour. La sección como relato — the section as a narrative — means that every material surface is considered in the context of the light that will fall on it.
Concrete Floor at Grade: Thermal and Tactile Performance
The ground floor of a courtyard house is the most important thermal plane in the building. A concrete slab-on-grade with appropriate insulation below stores the daytime heat admitted through south-facing glazing and the courtyard opening, releasing it through the evening. In a climate with significant diurnal temperature swings — Denver, Mexico City's dry season, the high desert — this passive thermal storage reduces the heating and cooling demand meaningfully.
In MÉTODO, the concrete floor at grade is finished to a polish level that reflects light without creating specular glare. A highly polished concrete floor adjacent to a courtyard distributes reflected sky light deep into the plan. A matte finish retains heat gain more efficiently but does not contribute to interior brightness. The specification is a balance between the two, determined by the light and thermal analysis for each room.
Joinery: Where Wood and Concrete Meet
The joint between concrete and wood is designed explicitly in every MÉTODO project. There is no applied trim, no casing, no edge banding that covers a poorly resolved transition. The concrete element terminates at a designed edge — typically a formed reveal or a shadow line — and the wood element begins at that edge with a tolerance of two to three millimeters.
This precision requires coordination between the concrete subcontractor and the millwork fabricator before either begins work. The reveal is cast into the concrete form. The wood is dimensioned to fit it. This is the process before the style: the joint is resolved in the construction documents, not improvised on site.
Próximos pasos
A contemporary courtyard house with concrete and wood interiors is the result of a material strategy, not a design mood. The hierarchy — concrete at structure and thermal mass, wood at acoustic and tactile surfaces — is established in the section and confirmed in the specifications before construction begins.
