DHRotterdam Zoo--Riviera Hall--1940

Because Rotterdam is one of the few zoo's designed solely by an Architect(that makes as much sense as hiring race car driver to fly your space shuttle, because he knows fast), in 2004 it was designated a national as well as a municipal monument. In fairness to LAM Architect, that mean's that there is limited space in which to work in an existing zoo, but that still doesn't explain the hyped "bulging walls", unless something hung out from an existing building and the wall's could not be built vertical, instead having to close in to the "onion shape" to squeeze between any over hang architecture of real beauty.
