through overhanging roofs, projections or niches; its outer
edge may be framed by steps or low walls. The projection of
the facade into this front area is supported by a correspond-
ing division, for example that between the Cathedral and the
Piazza Communale in Pienza. In the event that a > facade is
intended for a specific effect, the space shadow provides its
framework. If the facade in question is not flat, but fronts a
circular building, for example, then the radiance of the area
of influence extends on all sides, forming a radial force field
that presses outward and has a repellent effect, one that di-
minishes with distance.> time

within which the spatial structure determines the arrangement
and connection between spaces. The well-considered joining
together of the parts into a whole is a constitutive quality of
architecture, which receives its expression in the > composi-
tion as a result of an intentional design process (> concept).
Recognizable in this composition is an architectural > order,
when the spatial structure is subordinated to a comprehensi-
ble and rational rule. Many spatial structures that have been
established through history are represented by architectural
> types. A spatial structure is always a structural component
of a larger situation; it becomes possible for participants to
determine their positions within the structure, and to organize
their actions, either incorporating themselves into the struc-
ture, or exercising an influence on it.
The resources of spatial assembly are based on simple
connections and configurations developed from them. RoomsSpace-time relationship
