There comes a time when a more critical and analytical
approach is needed, and here formal perspective
drawings or computer simulation can be useful. But at the
conceptual stage, when designs are still fluid and where a
number of options need to be explored quickly, the sketch
can be invaluable. At this point the designer will be
relating the plan and form of the proposed building to
such matters as function; considering how to link patterns
of circulation to the section; and having initial thoughts
about structure and servicing. Depending upon the
project in hand, the designer will probably be grappling
with questions of site layout, landscaping and shelter.
These and many other issues lend themselves to the
freehand sketch, not as a means of recording a final
decision, but as a method of weighing up options from
the point of view of design and the organisation of form
and space.23.5
