But how do we define those spaces? In many, many ways, all involving the use of planes and openings within them.
We can define space with horizontal elements, and typically this involves the base (or ground) plane, elevated plane(s), depressed plane(s), and overhead plane. Translated, this means ceilings, floors, and any horizontals in between. A sunken living room floor would be an example of a depressed plane.

Space can be defined by vertical elements, as well, and may be the easier concept to understand since it typically involves walls -- we tend to think of space as areas defined around us, not above or below although they are included. As such, there are many more ways that a space can be defined: vertical linear elements, single vertical plane, L-shaped plane, parallel planes, U-shaped plane, and four planes: closure.

This and the next images also show examples of openings that define the space -- usually meaning windows, but can broadly be any opening within (or instead of) a plane. Openings occur in various positions within planes, at corners, and between planes.

This leads to the last point: light is a quality of architectural space, as is color, texture, scale, form, and so on.
Light can come from different sources, but it is typically natural or artificial. "Natural" includes sunlight and candlelight, while artificial comes from anything man-made (lampposts, flashlights, lanterns, lightbulbs, etc.). In the image above, light comes from both sources: the ribbon windows echo the showcase of cars along the edge of the room, while the overhead lighting spotlights the car underneath, evidently a prized possession.
Next posting will include the organization of space, and spatial relationships.
