In 1912, when I was working in The Hague, I first saw a drawing by Louis Sullivan of one of his buildings. It interested me.

I discovered by working with actual glass models that the important thing is the play of reflections and not the effect of light and shadow, as in ordinary buildings.

Where can we find greater structural clarity than in the wooden buildings of old? Where else can we find such unity of material, construction and form? here, the wisdom of whole generations is stored.

The demands of the time for objectivity and functionality must be fulfilled. If that clearly happens, then the buildings of our day will convey the greatness of which the age is capable, and only a fool will maintain that they lack it.

The building art is man's spatial dialogue with his environment and demonstrates how he asserts himself therein and how he masters it.

Industrialization of the building trade is a question of material. Hence the demand for a new building material is the first prerequisite.
