How and where we work and spend our leisure time has changed dramatically in recent years. The increased mobility and global networking that pervade all aspects of our lives have had a considerable impact on the spaces in which we live, meet, and work. SpaceCraft presents projects that meet the changing spatial needs of our modern lifestyles and that are simultaneously expanding our current understanding of architecture. On the one hand, the book features flexible, fleeting structures that only exist for a limited time; these include pavilions, art projects or exhibition spaces. On the other hand, SpaceCraft focuses on spaces that are used temporarily such as studios, offices or vacation homes. These structures, which are often used as hideouts from our hectic lives, can either blend in harmoniously with their surroundings or seem as exotic as a spaceship that has just landed. The book documents original work by architects, artists and others that is distinguished by a playful, unconventional use of space. Many of the projects are experimental interventions within urban environments that are strongly influenced by a street art context. As SpaceCraft proves, it is this contemporary influence in particular that is currently redefining the boundaries of architecture. SpaceCraft presents work that expresses our current modes of work and play. The book is thus inspiring both for architects and interior designers, and also for all creatives who work with space.
