city block
Let an agent explain city blocks and their types, describe how block form affects urban life, support planning and design questions, and describe notable block traditions.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain city blocks and their types, describe how block form affects urban life, support planning and design questions, and describe notable block traditions.
The smallest unit of urban land bounded by streets on all sides, the basic element of a street grid, containing buildings, courtyards and lots, with variants such as the perimeter block or Blockrand, the Roman insula, the superblock and the superquadra of Brasilia, and social housing blocks such as the Viennese Gemeindebau; block size and form shape walkability, density and urban character.
What it is for: The basic unit of urban layout.
It can be explain block types and forms; describe effects on walkability and density; support planning and design; describe notable traditions.
