In design, "functionality", "proportions" and "aesthetics" are my principles.
In a designed space should be a functional solution where all needs. So you can functionally take full advantage of life.It must be mentioned from space as well as fullness. We can say that the universe was created in a space on these principles.
All living and non-living beings are created with a measures of "proportion" in an orderly manner
We call it "absolute proportionness".. Everything in the natural world is called the "golden ratio" to the perfect balance of this created value in a certain arithmetic..A balanced rate away from extremism is a must in life and locality.
.Aesthetics represent "sensitivity" that appeals to the added emotions.
