With this fourth O'Neil Ford Duograph, The Center for American Architecture and Design, together with the O'Neil Ford Chair in Architecture at The University of Texas at Austin, are publishing another set of buildings by two architects from one country. Tatiana Bilbao and Derek Dellekamp are, without doubt, two outstanding figures of contemporary Mexican architecture. Their body of work is not only extensive - it also shows a research approach quite unlike that of any other of their international colleagues. This volume includes sketches, drawings and photographs, as well as two analytical essays by Mexican critics and statements on the two buildings. All provide the discursive context as well as insights into the selected buildings' significance.
