Since the beginning of building enclosures for human habitation, most forms that have come into being have been variations of the rectangle.
We live primarily in boxes.
This form has come to be the best for many reasons.
Over ninety percent of what we see are the walls, floors, and ceilings of this rectangle.
Various openings, primarily for functions and light, are put into this box.
To achieve the highest levels of aesthetics, two aspects should be addressed.
What is the optimum design of the relationship between the space and the outside world?
What is the optimum design of the box itself and the surrounding spaces?
Ideally, the expenditure of design resources should be expended somewhat equally for the walls, floors, ceilings, and furnishings of the space.
Most of us do not live in an ideal world and have to make choices accordingly.
Living in the real world, what aspects are considered for the complete aesthetic and personal expression of the spaces in which you live?
Food for thought.
