O PE NINGS BETWEEN PLAN ES

A vertical opening that extends from the floor to
the ceiling plane of a space visually separates and
articulates the edges of the adjacent wall planes.

If located at a corner, the vertical opening will erode
the definition of the space and allow it to extend
beyond the corner to the adjacent space. It will also
allow incoming light to wash the surface of the wall
plane perpendicular to it and articulate the primacy of
that plane in the space. If allowed to turn the corner,
the vertical opening will further erode the definition of
the space, allow it to interlock with adjacent spaces,
and emphasize the individuality of the enclosing
planes.

A horizontal opening that extends across a wall
plane will separate it into a number of horizontal
layers. If the opening is not very deep, it will not erode
the integrity of the wall plane. If, however, its depth
increases to the point where it is greater than the
bands above and below it, then the opening will become
a positive element bounded at its top and bottom by
heavy frames.

Turning a corner with a horizontal opening reinforces
the horizontal layering of a space and broadens the
panoramic view from within the space. If the opening
continues around the space, it will visually lift the
ceiling plane from the wall planes, isolate it, and give
it a feeling of lightness.

Locating a linear skylight along the edge where a wall
and ceiling plane meet allows incoming light to wash
the surface of the wall, illuminate it, and enhance the
brightness of the space. The form of the skylight can
be manipulated to capture direct sunlight, indirect
daylight, or a combination of both.
