High-quality residential structures are much more than merely a series ofdifferent floor plans. First and foremost, the urban apartment house mediatesbetween the private refuge and the public space of the city. In theprocess, boundaries between inside and outside are negotiated on a widevariety of scales. Housing+ focuses on investigating spatial and architecturalas well as social and communicative interfaces in residential construction.The publication is divided into four chapters – “Urban Planning,” “TheGround Floor,” “Building Structure,” and “Façade” – to which sixty-seveninternational projects are assigned. These four thematic focuses are discussedcomprehensively in the essays that introduce the chapters, and the individualprojects are analyzed in brief under these same aspects. Comparable plans—drawn especially for this book—supplement the typological descriptions. The broad spectrum of projects selected covers urban apartment block construction from towers, block structures, row houses, and gaps between buildings, to housing complexes in outlying urban areas.
