D/H and W/D Proportions of the Townscape

An important aspect of townscape composition depends on the ratio of street width to building height. These proportions, using D for the distance between buildings on both sides of the street, and H for the height of the adjacent buildings.

When D/H < 1, the space grows crowded and cramped

When D/H = 1, a balance is achieved between height and distance

As D/H grows larger, the space becomes more open

Figure-ground analyses are powerful tools for identifying the textures and patterns of the urban fabric as well as problems in its spatial order, but can lead to a static and two-dimensional conception of space.
