A somewhat dry and technical look at sixty blocks around Alamo Square which attempts to explain residential design and building traditions over 100 years of development. Relying heavily on Sanborn atlases, the work is very detailed, sometimes to the point of exhaustion. Thank goodness for lots of accompanying photographs which show 1890s mashed up against 1930s mashed up against 1970s architecture. Hodgepodge blocks. Victorian-esque feel to the area because that came first and first is hard to eradicate. Corner lot mansions began to be abandoned (theorizes Moudon) because of the access to suburbs that cars provided in the 1920s and 30s. This is the book that inspired the author of San Francisco, la grille sur les collines.
