By maintaining its active, evolutionary form, the block can accommodate low and high densities (even higher than the ones requested by this brief), and also create different qualities of open space. Such a block can shape public streets, links, passages etc, as well as piazzas, playgrounds, greenery, parking spaces…, thereby maximizing communal space. The master plan evolves as a flexible system of blocks, which modifies itself in the desired social structure, area size and urban network.
