Book excerpt: In this book selected contemporary architects and critics focus on the theme of rigor in architecture. They investigate the difficulties in sustaining the clarity of a design idea from its inception to the final details and the corresponding difficulty the critic has in tracing this process. A project section includes the work of emerging practitioners from Europe and the United States. The book concludes with a section on the work of Eileen Gray and Heinrich Tessenow. Translations of writings by the two architects are included, notably Tessenow's book Of House Building and Such Things along with appraisals of their projects by commissioned authors.
