The project comprises the rebuilding of a church of an old lumber town on a lagoon in the province of Campeche in Mexico. Wood from the original chapel and other buildings is recycled to erect a modular structure adapted to local timber construction. Respecting the site, the new church and community center define a square for public use, including cultural and educational programs that complement religious activities. The building ensemble uses passive ventilation; rainwater for drinking and irrigation is collected from the roof and outdoor surfaces; polluted water from the lagoon is cleaned.
