A century after Napoleon III's reign, new housing needs and the rise of a new voluntarist Fifth Republic began a new era of Parisian urbanism. The new era rejected Haussmannian ideas as a whole to embrace those represented by architects such as Le Corbusier in abandoning unbroken street-side façades, limitations of building size and dimension, and even closing the street itself to automobiles with the creation of separated, car-free spaces between the buildings for pedestrians. This new model was quickly brought into question by the 1970s, a period featuring a reemphasis of the Haussmann heritage: a new promotion of the multifunctional street was accompanied by limitations of the building model and, in certain quarters, by an attempt to rediscover the architectural homogeneity of the Second Empire street-block.
