The Osa Peninsula, located in the southwestern region of Costa Rica between the Pacific Ocean and the Golfo Dulce, is an integral part of the land bridge between North and South America. The migration of species from both north and the south played a large role in making the Osa Peninsula one of the most biologically diverse places in the world. Intricately woven ecosystems create a delicate balance between tropical rainforests, estuaries, riparian forests and thousands of endemic species. This remote and pristine area is home to at least half of all species living in Costa Rica and comprise 4% of the world’s population.Deforestation and a rapidly rising tourism sector have created a need for conservation and environmentally responsible development. Presently, 80% of the Osa is protected and 99% of Costa Rica’s energy comes from clean sources aiming for carbon neutrality by 2021. Ecotourism becomes a way to promote Costa Rica’s rich natural heritage while protecting its unique and dynamic flora and fauna. Using the metaphor of the rainforest, a cluster of tropistic structures rise up into the forest’s canopy allowing dwellers to observe and immerse themselves into the diverse variety of species inhabiting the dense foliage of the various canopy levels. The vertical typology minimizes intervention into the site protecting the surrounding environment while allowing one to feel fully integrated. 80% of life in the rainforest exists in the trees. The forest is vertically divided into five layers each having its own unique plant and animal life, with the canopy layer containing the greatest biodiversity. This dynamic interplay between layers serves as a metaphor for the building vertical typology and minimal floor plate.
