Casa Caiman is a coastal house in Barra de Navidad, Oaxaca, conceived as part of a larger settlement of houses, villas, and shared amenities positioned between the Pacific Ocean and a lagoon. Organized as a sequence of low plinths and gabled volumes, the project draws on regional roof forms, timber screens, and pigmented concrete construction to mediate exposure, privacy, and climate while maintaining a close visual and material relationship with the dune landscape.

The house is conceived as a sequence of shaded platforms and screened rooms where structure, climate, and landscape are inseparable from daily life.

Coastal Siting and Settlement Logic
Casa Caiman occupies a narrow environmental threshold between the Pacific shoreline and the inland lagoon, a condition that poses its primary architectural problem. Rather than treating the house as an isolated object, the design situates it within a broader field of dispersed structures spread across the coastal site. This settlement logic relies on repetition and variation: pigmented concrete walls, palapa roofs, timber lattice screens, and stepped platforms recur across the complex, establishing a shared architectural language that ties individual dwellings to collective amenities and to the larger terrain.
The building remains low and laterally extended, which is a significant response to the exposed dune landscape. In aerial views, the house reads less as a singular mass than as a calibrated set of roofed fragments resting lightly on the ground. Its stepped plinths negotiate changes in level while reinforcing the site’s horizonality. This strategy prevents the house from asserting vertical dominance over the beach and instead aligns it with the scale of scrub vegetation, shifting sand, and the distant mountain range.
The siting also organizes perception. Approaching from the landward side, the volumes appear embedded within cactus, palms, and dune grasses. Toward the ocean, the architecture opens into broad terraces and water edges that frame the surf. The result is a house that is visually grounded yet highly responsive to long views, using orientation and section rather than monumentality to establish presence.
Plan Organization and Spatial Hierarchy
The plan is structured by a central axis formed by two parallel concrete walls. This linear spine does more than connect rooms. It acts as a mediating armature between two distinct spatial regimes: a communal wing oriented toward gathering, eating, and open occupation, and a more protected private wing made up of bedroom volumes. The clarity of this bifurcated arrangement gives the house strong legibility, allowing circulation, privacy, and exposure to be organized without excessive enclosure.
The public wing is housed beneath a large gabled palapa roof whose scale exceeds that of the adjoining rooms and establishes it as the principal social volume. Living, dining, and kitchen functions are held within a largely open pavilion where boundaries are defined by columns, platforms, and furnishings more than by walls. This open condition allows the sea and sky to remain present within everyday domestic activity. By contrast, the bedrooms are placed in smaller twin gabled forms, each more compact and more tightly screened, producing a measured transition from collective openness to individual retreat.
Open passages between the volumes are essential to this hierarchy. They preserve continuity of air and sightlines while also marking thresholds between one domain and another. Instead of relying on corridors or sealed interiors, the house uses framed gaps, exterior crossings, and shifts in roof scale to structure movement. Spatial separation is therefore not absolute; it is tempered by recurring materials, aligned views, and the constant nearness of climate and landscape.
Material Assembly, Vernacular References, and Atmosphere
The project draws heavily on local coastal building traditions, particularly in its use of palapa roofs and timber screening, but these references are reassembled through a more tectonically explicit vocabulary. The thick pigmented concrete walls give the house its mass and permanence, while the exposed roof structures in timber and palm thatch articulate a distinct lighter layer above. This contrast between earthen weight and fibrous lightness is central to the architectural reading of the house. It produces a composition in which support, enclosure, and shelter remain legible as separate but interdependent systems.
The coral-toned concrete is especially important. Hand-trowelled and lightly textured, it operates as both structure and chromatic field, changing with the angle and intensity of daylight. In full sun, the surfaces appear dense and absorptive; at dusk, they become more saturated and visually warm; under screened light, they register fine gradients of shadow. Travertine platforms in the public areas introduce a cooler mineral surface that heightens the contrast between exterior terraces and the polished pigmented floors inside.
Tzal am lattice screens provide the most nuanced atmospheric layer. Their porosity allows rooms to remain visually veiled rather than sealed, and they transform sunlight into thin bands and scattered points that move across floors, beds, and walls throughout the day. At night, the relation reverses, with illuminated interiors turning the screened bedroom volumes into lantern-like enclosures. These effects are not incidental embellishments but consequences of a material system that treats privacy, ventilation, and light modulation as one and the same architectural problem.
Climate Responsive Design and Environmental Mediation
In a hot coastal setting marked by intense sun, humidity, and onshore breezes, the house is shaped by passive environmental strategies rather than by sealed interior conditioning. The large open-sided pavilion allows prevailing air to move freely through the main living spaces, while the placement of openings and screens in the bedroom volumes supports cross ventilation. The plan avoids deep, landlocked rooms and instead keeps most occupied areas close to exterior edges, where air movement and shaded exposure can be maintained.
The palapa roofs are essential climatic devices. Their deep overhangs reduce direct solar gain, and their thick thatch builds a thermal buffer between occupied space and the exposed roof surface. Timber lattice elements perform a similar role at the scale of the facade. They admit daylight and air while reducing glare and filtering low-angle sun, particularly in the more private wing. What might appear formally consistent across the project is therefore also technically responsive, with each element serving to temper radiative heat and maintain habitable outdoor-adjacent interiors.
The house also converts environmental forces into spatial experience. Reflections in the infinity pool intensify the perception of the roof geometry and changing sky conditions, while the pigmented surfaces register subtle color shifts from morning to twilight. Screen shadows animate otherwise static walls, and the open terraces keep the sound and movement of the ocean close to daily occupation. Climate is not treated as a background condition to be neutralized but as a medium through which the architecture is perceived and organized.
About Bloqe arquitectura
Bloqe arquitectura is a Mexico-based architecture studio led by Jorge Esquer Luque. The practice works across residential, hospitality, and master-planning projects, with a strong interest in regional materials, vernacular roof typologies such as palapa, and the relationship between architecture and coastal landscape.
