In its 85th year of existence, the architectural practice founded in 1937 by a very young Juan Sordo Madaleno, has decided to publish this unconventional monograph which compiles the most ambitious projects built (and not built) within the context of the transformation, and which at the same time reflect and determine the evolution urban and rural landscapes of post-revolutionary Mexico. From the very first constructions, the firm has been a pioneer not only in the erection of modern buildings, but also in inherently urban architectural designs, fundamental components of overlapping urban scales. This book includes contributions from some of the leading thinkers in urban architecture today, highlighting the commitment that has guided a unique family of architects for three generations.
