The Spanish Pavilion will examine the concept of Interior as the overall theme of the pavilion. As the curator Iñaki Ábalos explains, ‘there is no architecture without an interior; there is no idea of architecture if there is no thought of interior in all aspects. The interior speaks of space, and space is, by definition, the theme of architecture.’~The result of exploring the central theme of Interior will be approached as an investigation through different examples of Spanish contemporary architecture that evidence one of the distinguishing features of its identity and essential core: the need to understand or interpret it as an environmental construction.
