The city block is a typically urban element that, historically, has appeared in different forms and designs, structurally shaping city planning guidelines. When observing urban fabrics in cities such as Barcelona, Paris and Copenhagen, one can see significant variation between block models. This defines their landscapes and dynamics in countless ways. Style and format alterations, volumetric changes in the relationship between full and empty spaces, and modifications in connections to the surroundings are some examples of typological particularities that differentiate them. Blocks, therefore, are often emblematic and representative not only of certain urban planning models developed throughout history but also of their cities.
