A deformed wheel is a semi-grid, or hub, of lines near the centre: strong integrators which link this semi-grid to the edges, like spokes, and some edge lines are also integrated, forming a spatial rim. This structure is usually the main public space structure, while less integrated residential areas form in the interstices of the ‘wheel spokes’ (the streets connecting the centre to the edge.
