Casa Leria by TAC Taller Alberto Calleja: A Low-Impact Coastal Sanctuary in Puerto Escondido

Casa Leria, designed by TAC Taller Alberto Calleja, is a residential sanctuary nestled within the lush coastal vegetation of Puerto Escondido, Oaxaca. Set on a generous 3,500-square-meter site in the seaside community of El Tomatal, this 1,100-square-meter home redefines tropical modernism through ecological sensitivity, modular architecture, and bioclimatic design strategies.

A Discreet Architectural Footprint

The central challenge of the project was to respond to the natural context with minimal impact while still accommodating the full programmatic needs of a family home. Rather than creating a monolithic structure, the architects deconstructed the program into eight discrete modules, each addressing a specific function:

• A social core housing a palapa, kitchen, and pool
• A sculptural social tower
• Independent bedroom units
• A service wing and parking area

These elements are dispersed across the site and connected by lightweight circulation bridges, allowing the architecture to integrate gently into the existing vegetation without major disruption to the land.

A Reimagined Palapa: Innovation in Traditional Forms

The heart of Casa Leria is the social space, enclosed beneath a dramatic reinterpretation of the traditional Mexican palapa. By stretching and rotating its typical geometry—playing with slope, span, and scale—TAC Taller Alberto Calleja created a distinctive architectural gesture that sets the tone for the entire residence.

Rotated 45 degrees eastward, the main palapa opens diagonal views toward the ocean while creating a ventilated courtyard at the center of the home. This subtle shift in orientation enhances natural ventilation, light flow, and thermal comfort, while simultaneously freeing the rear of the site for lush reforestation.

Regenerative Design: Architecture that Heals the Land

A defining aspect of Casa Leria’s sustainability strategy is the transference of ecological responsibility to the rooftops. The footprint disturbed by construction is conceptually “returned” through the integration of green roofs atop each module. These planted surfaces not only restore the site’s vegetative layer but also contribute to passive cooling, thermal insulation, and the house’s overall bioclimatic performance.

An Architecture of Sensory Journeys

Casa Leria invites its occupants to experience space through a sequence of intimate pathways and framed views, blurring the boundaries between interior and exterior. From shaded terraces and open-air lounges to secluded bedrooms embedded in the greenery, each moment of the home is designed as a sensorial encounter with the coastal landscape.

Through this fragmentation, the architects have made a large home feel unobtrusive and human-scaled, allowing it to disappear into the site’s natural rhythms. The result is not just a residence, but a landscape-embedded living experience—a model for contextual and low-impact architecture in tropical environments.
