If a building becomes architecture, then it is art.
~ Arne Jacobsen
I don't see that any buildings should be excluded from the term architecture, as long as they are done properly.
Proportions are what makes the old Greek temples classic in their beauty. They are like huge blocks, from which the air has been literally hewn out between the columns.
And when an architect has designed a house with large windows, which is a necessity today in order to pull the daylight into these very deep houses, then curtains come to play a big role in architecture.
Architecture tends to consume everything else, it has become one's entire life.
If architecture had nothing to do with art, it would be astonishingly easy to build houses, but the architect's task - his most difficult task - is always that of selecting.
In addressing a task, one almost always has several possible options, sometimes only a few, and they may all be practical and functional. But they lack the aesthetic aspect that raises it to architecture.
The primary factor is proportions.
You will soon find that I am a bit obsessive about my work. And that is a little sad, one often feels strangely restricted, not finding time to simmer, although one actually has many interests.
With a painter or a sculptor, one cannot begin to alter his works, but an architect has to put up with anything, because he makes utility objects - the building is there to be used, and times change.
But inspiration? - That's when you come home from abroad and are asked: Well, have you found inspiration? - and fortunately you haven't. But the impressions sink in, of course, and may emerge later: None of us has invented the house; that was done many thousands of years ago.
