As a discipline and practice, architecutre needs periodic infusions of wit, generous acts of criticism, and intelligent reformulations of precepts. Dr. Alberto Altés and Oren Lieberman have edited just such a volume and then some. The conceptual grounding for 'immediate interventions' is matched by an attention to formal qualities, social agendas, and political implications of design, evident in this richly illustrated book. A range of authors offer formulations of a new agency for architecture, its students, its practitioners, and its publics. Intravention... fundamentally reshapes our ideas about environmental experience. Dana Cuff, Director, cityLAB/Professor, Architecture and Urban Design, School of the Arts and Architecture, UCLA Alberto Altés Arlandis (eds.) is an architect, researcher and Lecturer at Umeå School of Architecture, in Sweden. His work interrogates the loss of critical and utopian impetus in architecture and explores the possibilities of the moving image as an apparatus of spatial critique and encounter. Oren Lieberman (eds.) is Professor of Architecture and Dean of the Faculty of Art and Design at the Arts University Bournemouth and a Guest Professor at Umeå School of Architecture. Together they direct the Laboratory of Immediate Architectural Intervention, exploring architecture as a relational, political, social and ethical practice that unfolds in the making of the world through intraventions. Intravention, Durations, Effects defines architecture not as an 'it' but as a process; in that sense, architecture is a verb: to architect. Rather than refer to the (paradoxical) limiting of intervention's 'in-between', it posits a new concept: intravention. Intra's focus on the 'within' establishes intraventions as (already) a part of the spaces and times in which they are 'intravening'.
