AXIS

The axis is perhaps the most elementary means of organizing
forms and spaces in architecture. It is a line established by two
points in space, about which forms and spaces can be arranged in
a regular or irregular manner. Although imaginary and not visible
except to the mind’s eye, an axis can be a powerful, dominating,
regulating device. Although it implies symmetry,
it demands balance. The specific disposition of elements about
an axis will determine whether the visual force of an axial
organization is subtle or overpowering, loosely structured
or formal, picturesque or monotonous.

Since an axis is essentially a linear condition, it has qualities of
length and direction, and induces movement and promotes views
along its path.

For its definition, an axis must be terminated at both of its ends
by a significant form or space.

The notion of an axis can be reinforced by defining edges along its
length. These edges can be simply lines on the ground plane, or
vertical planes that define a linear space coincident with the axis.

An axis can also be established simply by a symmetrical
arrangement of forms and spaces.
