Each crossing of the interface is accompanied by a change of condition
and that nothing which separates and links accommodates the condition of
"active paralysis" as a necessary condition for going beyond
it. Nowadays there is a tendency towards a reduction of sense, a loss of
the importance of the interface.
Our intention is to create an event which is both less repetitive and
constantly changing, which is capable of amazing, which leaves a sign, which
represents a system open to new developments; an event which apart from
being passages must provide a stimulus to personalisation in forms, in position,
in the ways which allow such a passage; an event which takes mainly expressiveness
into consideration, which reevaluates the other senses (hearing, touching
. . .) and not only sight, which integrates supplies or technological mechanisms.
Architecture organises the space which surrounds man like a whole because
neither of the parties has functional autonomy and both are evaluated only
by how they shape the space in which they are situated and delimited.
Architecture relates to the all the person, and that is to the sum total
of his physical and mental (or virtual) needs which we have divided into
three areas:
- - The field of the symbolic function focuses "on the object.
Attention is concentrated on the efficiency of the relation between the
thing and the sign which signifies it. The symbol, function of visual expression,
enters architecture when some configurations transmit a conventional meaning".16 The symbolic form is distinguished
as an "omnicomprehensive medium capable of structuring a multiple
and simultaneous response to various subjectivities, namely the symbolic
forms which can be filled",17
"each time the context of reference changes, of contingent contents".18
- The field of the aesthetic function focuses "on the subject.
The aesthetic sign does not operate in a single reality, as the symbolic
sign does, but reflects in itself reality as everything".19 Moreover, it does not act
on reality but protects itself from all those realities which man has lived
or which can still be lived, from all the universe of things and facts.
The aesthetic function will be adaptive in relation to the various ideas
of subjective beauty.
- The field of the practical function identifies various formal
and technological matrices and is critical of social consensus as a spontaneously
comprehensible way of using things. Architecture must be adaptive, and
therefore open to various expressive and sensorial uses and open to adopting
technological devices.
The structure of interfaces is composed of a boundary nucleus and directly
connected progressive filtered spaces which surround it. The organisation
evolves with variable sequences of individual constitutive elements and
of levels of departure and arrival and therefore is ready to support
subsequent and unpredictable meanings and, why not, uses? (parades and concerts
at the Trinità dei Monti were unthinkable at the time of planning).
These fields are never independent but to the contrary are hard to break
up, and so the various layers overlap and become stratified. |
