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.

Clearly, if a building is not functionally and technically in order, then it isn't architecture either, it's just a building.

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.

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.

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.

Carrying out the thing, getting it to the point when one might say: There, now it is good - that point is hard to reach. Often, one sets very high goals for oneself. Perhaps too high.
