The Institute for Advanced Architecture of Catalonia (IAAC) calls its 9th Advanced Architecture Contest as a global reflection to rethink human settlements at a time when our natural environments and the human habitats are more clearly intertwined.

We look to the model of Biocities, cities that follow the principles of ecological principles in order to promote life and biodiversity, to provide us with potential design solutions. How can we reimagine our cities as Biocities, capable of creating an ecologically attuned and reciprocal relationship with nature? This year's competition challenges students and professionals from all over the world to propose how to design urban spaces, cities, buildings, objects, or solutions of any scale, directed towards the transition to Biocities. The contest encourages participants to propose a design at any scale, anywhere in the world, that reflects different cultural, environmental, economic, or social conditions.
