Marine Metabolic Roof is an attempt towards increasing marine biodiversity with an Architecture intervention, using various methods to echo the marine environment onto the rooftop of the existing building, which provides a healthy environment for various endangered species to incubate and grow up with controlled careful space and releases all the species to the sea once the species reaches to the mature age and lays eggs.

To successfully create such marine space with a self-sustaining loop, the system requires micronutrients for species to survive. Thus, fetching water from the sea seems an ideal option.




The effect of Climate change and Global warming on the marine ecosystem has been seen in recent years. This, unfortunately, is the reason behind a lot of species are facing the threat of being extinct.

Tacking the global phenomena with an architectural intervention requires some detailed local parameters, which tackle local problems related to the marine ecosystem.


Considering all the parameters and phenomena, the building suitable for particular intervention is located at Barceloneta beach, one of the most visited areas by locals and tourists, PRBB (Barcelona Biological Research Center) designed by Albert de Pineda, Manel Brullet.
