The project which deeply integrates architectural design with local environmental, cultural, and social contexts has experienced challenges that have slowed progress – that include addressing regulatory requirements and adapting to extraordinarily high rainfall. Guayacán wood foundations, the framework for the platform and some structural columns have now been completed; the main structure for the sanitary unit module has also been completed, representing approximately 28% of the total build.

Adapting to Environmental and Climatic Conditions

The project’s most immediate hurdle came in the form of regulatory requirements for the sustainable use of Guayacán wood, a critical material used for the school’s submerged foundations. The timber is highly prized for its durability, density, and resistance to moisture and decay, making it suitable for challenging environments—like the submerged foundations of the school. Securing the necessary environmental permits from the regional authorities was a key early milestone, ensuring the wood was sourced responsibly and with certification.

Further delays arose in the latter part of 2024, when the region experienced severe and sustained rainfall. A red alert for flooding was declared, making the transport of the building materials impossible and halting construction for nearly three months. Despite these challenges, the team has remained committed to the school’s community-centred vision. Currently, 100% of the workforce consists of residents from Nueva Venecia, fostering a strong sense of ownership and inclusion.

Lessons in Contextual and Participatory Design

The project reinforces the importance of designing for place. Its palafitic (stilted) structure responds directly to the area’s aquatic geography, while material choices and construction methods reflect a careful study of local traditions and climate conditions.

Key lessons include the need for early engagement with regulatory processes in environmentally sensitive areas, and the powerful impact of involving the local community in both design and construction. This participatory approach not only builds trust but also strengthens long-term stewardship of the project.

Recognition and Next Steps

Despite construction delays, the project has already garnered international attention. In 2024, it received an Honourable Mention at the International Architecture Biennial of Costa Rica (Bienal Internacional de Arquitectura de Costa Rica) and was named a Finalist in the Professional Category of the Latin American Sustainable Architecture and Urban Design Award (Premio ADUS LATAM).

The Holcim Foundation will continue to follow the progress of the San José de Nueva Venecia School as it advances toward completion—and as it continues to model resilient, inclusive, and sustainable building practices in a uniquely challenging context.
