For over a decade, Brooklyn-based SO-IL has been envisioning houses, housings and other projects in between and adjacent to domestic spaces. Reflecting on the state of housing design today – often constrained by pressures of production – SO-IL approaches these sites with generous experimen- tation. In this book, the design office’s attempt to “hack” the codes, cores, courts and corridors takes center stage, exemplified by a selection of SO-IL’s most recent projects, exploring concepts includ- ing porosity, connectivity, community and orientation in urban living. Appealing to students and professionals alike, In Depth examines how housing might promote the well-being of its inhabitants by presenting new typologies for our ever-more urbanized world.
