What is Architecture? [PDF ebook] 

Architecture can influence the way we feel, and can help us along as we go about our lives, or sabotage our habitual ways of doing things. The essays collected here challenge, and help to define a view of architecture which ranges from the minimal domesticity of Diogenes‘ barrel, to the exuberant experiments of the contemporary avant-garde. There are essays by philosophers, architects and art historians, including Roger Scruton, Bernard Tschumi, Demetri Pophyrios, Kenneth Frampton, Diane Ghirardo and David Goldblatt.
