Which urban shape is recognized for its absence of articulation?

The urban shape recognized for its absence of articulation is the sheet. Sheets are characterized by their flat and uniform nature, lacking any defined or distinct features that would provide a sense of variation or complexity. This gives sheets a continuous expanse, making them visually and spatially cohesive, yet homogeneous. In urban design, this concept can manifest in large, uninterrupted developments, landscapes, or surfaces that do not involve significant differentiations or divisions within the space.

In contrast, other options introduce elements that provide articulation or complexity. The constellation refers to a configuration of various elements or forms that relate to each other but retain individual characteristics, thereby creating a more dynamic urban shape. An articulated sheet modifies the flatness of a basic sheet by introducing variability in form or purpose, while a woonerf, which is a shared space designed primarily for pedestrians and cyclists, often showcases a playful and integrated design that emphasizes interaction and complexity.
