Today 80 percent of the world’s zoos are located in cities, and a
vertical zoo seems as inevitable as a vertical farm. A new competition
in Buenos Aires, Argentina asked architects to design a vertical zoo
for a location in a natural reserve on the city’s riverfront. Organized
by Arquitectum and TodoObras
magazine, the brief was to design a structure that would become a new
urban landmark, one that would accentuate a growing area of the city
and at the same time complement the natural character of the reserve. James Biber has designed a vertical zoo that is an urban take on
Charles Darwin’s evolutionary tree of life, a phylogenic arrangement of species in vertical formation.
