Stadia as a building typology has been a central object of my career as an architect at academic and practical levels. Currently I´m focused on the research of design methodologies that can be applied to stadia in order to achieve beneficial legacies. I´m a member of the Stadia Lab where scientific design analysis is developed producing data that can improve the effects of stadia on its built environment. Professionally I´ve worked with stadia proposals for the 2014 FIFA World Cup, stadiums and arenas for private and public clients where I´ve been able to observe from a privileged point of view the distance of the design process from the advertised legacies as well as the significant impact of large scale stadia to the urban landscape of its host cities. Although the potential legacy related to stadia is very questionable, there´s is a clear necessity to review this building´s archetypal in order to take a broader consideration of social, historical, economic and urban realities, finally becoming a catalyst of urban development.
