In portuguese entre, the word for in-between, conjures uponnotations that far exceed its English equivalent. Indeed the 'in-between' explored in this book is a more abstract and farreaching notion- physical, spatial and temporal. By retaining the Portuguese term in this new english edition, Entre signals Vazio S/a's indebtedness to Brazilian culture and seeks to keep intact this original notion, for which there seems to be no satisfactory english translation. Founded in 2002 by carlos Teixeira, Vazio S/a is as much a working practice operating through private and public sector commissions, as it is a research hub for architectural experimentation. The studio's integrated vision of design encompasses architecture, landscape architecture and urban design and, in addition to more conventional commissions, Vazio S/a works collaboratively with artists, performers and social groups to develop contemplative urban interventions and investigate relationships between contemporary architecture and culture.
