A semi-private courtyard in central Mexico is a spatial negotiation between the street and the house. It is not the street — it is entered, not viewed from the sidewalk. It is not the house — it is accessible to guests before they cross the main threshold. It occupies the social middle ground that urban Mexican residential architecture has articulated in various forms since the colonial period.
The Social Geography of the Semi-Private Courtyard
In the residential architecture of central Mexico — the states of Jalisco, Guanajuato, Querétaro, Puebla, and the Federal District — the relationship between the street and the house is not binary. There is always an intermediate zone: the zaguán, the portal, the forecourt, or the entry courtyard. This intermediate zone has a specific social function. It receives guests who are not yet invited inside, provides a space for conversation that is neither the street nor the interior, and marks the threshold between public and private life.
In contemporary residential design, the semi-private courtyard continues this spatial function. The geometry is the same: enclosed, accessible by controlled entry, visible from the street only as a controlled opening in a solid facade. The materials and proportions are contemporary, but the spatial logic has not changed because the social conditions that produced it have not changed.
Defining the Boundary: Facade, Gate, and Wall Height
The semi-private courtyard is defined by what it is not: not the street, not the house. The boundary is created by three elements:
- The street facade wall: Solid or slatted (allowing light and air, but not direct vision), with a height that prevents casual observation from the street. In central Mexican urban conditions, 2.2 to 2.5 meters is the standard minimum height. Above this height, the facade begins to feel fortified rather than welcoming — which is the correct register for a private courtyard but not for a semi-private one.
- The entry gate: The gate defines the controlled transition between street and courtyard. Its design signals the character of what is beyond: a heavy wooden gate on a stone surround signals permanence and weight; a slender steel gate in a narrow opening signals precision and selectivity.
- The wall height relative to the courtyard floor: If the courtyard floor is below the street level — a common condition on sites with significant grade — the walls appear higher from inside than from outside, increasing the sense of enclosure without increasing the exterior facade height.
The matrix of options for these three elements is evaluated against the specific street conditions of the site: the level of pedestrian traffic, the noise environment, the adjacent building heights that determine visual exposure, and the desired social register of the threshold.
Asoleamiento in Central Mexico: Sun Angles and Courtyard Design
Central Mexico, at latitudes between 18 and 23 degrees north, receives intense overhead sun from April through August. A semi-private courtyard at this latitude that is fully open to the sky will be uncomfortably hot in the afternoon during the warm season. The shading strategy for the semi-private courtyard is therefore a functional requirement, not a design preference.
The asoleamiento analysis for central Mexican sites shows that the midday summer sun is nearly vertical — between 70 and 90 degrees above the horizon. A tree canopy or a shade structure at the courtyard center provides effective shading for most of the day. The low winter sun angle (between 43 and 68 degrees at noon, depending on latitude) means the same canopy admits substantial solar gain to the courtyard floor in the winter months.
This seasonal alternation — shaded in summer, sunny in winter — is what a deciduous canopy tree provides automatically. In MÉTODO projects at central Mexican sites, the planting strategy for the semi-private courtyard is designed with the mature canopy dimension at year ten, not the planting dimension at year one.
Climate Performance: Evaporation and Thermal Comfort
The semi-private courtyard in central Mexico benefits from evaporative cooling. The temperate climate at altitude — CDMX at 2,240 meters, Guadalajara at 1,570 meters, Querétaro at 1,820 meters — has low relative humidity in the dry season (November through April) and moderate humidity in the rainy season (May through October). During the dry season, a water feature or irrigated planting in the courtyard provides meaningful evaporative cooling to the adjacent space.
A traditional strategy — the central fountain surrounded by shade trees — is functionally correct. The water surface evaporates continuously in the dry season breeze, and the tree canopy traps the cooled air at occupancy level. This combination lowers the perceived temperature in the courtyard by 4 to 8 degrees Fahrenheit on a dry afternoon.
In MÉTODO, the evaporative cooling benefit is estimated using the site's wet-bulb temperature data before the water feature dimensions and the planting density are specified. The estimate confirms that the design delivers a measurable comfort benefit, not just a visual one.
The Entry Sequence: Compression and Expansion
The semi-private courtyard is most effective when approached through a compressed entry sequence. Moving from the street through a narrow gate or a low-ceiling vestibule into the open courtyard produces a spatial experience of compression followed by expansion — a technique that makes the courtyard feel larger and more welcome than its dimensions alone would justify.
This sequence is designed in the section. The section shows the height of the gate opening (typically lower than the courtyard wall, to signal entry without full transparency), the height of the courtyard walls, and the sky angle visible from the entry point. A well-designed entry sequence to a semi-private courtyard reveals the sky gradually, not all at once — each step into the courtyard opens more of the overhead view until the full courtyard is entered.
From Semi-Private to Private: The Inner Threshold
The semi-private courtyard leads to the main entry of the house — the door that marks the transition from social to private. This inner threshold can be designed with more weight than the street gate: a heavier door, a protected overhang that marks the transition, a change in floor material at the threshold. Each of these elements signals the passage from the social zone to the inhabited interior.
In a double courtyard plan, the semi-private courtyard is the outer layer and a fully private courtyard is the inner layer, with the inhabited program between them. In a single courtyard plan, the semi-private courtyard is the entire outdoor space — simultaneously the entry sequence and the primary outdoor living area.

The semi-private courtyard in central Mexico is a spatial and social instrument designed for the specific conditions of urban Mexican residential life. It is not a generic forecourt — it is a designed threshold with climate, acoustic, and social performance requirements that are resolved in the schematic design phase.
