Pay attention to the forms in which the locals build. For they are the fruits of wisdom gleaned from the past. But look for the origin of the form. If technological advances made it possible to improve on the form, then always use this improvement. The flail is being replaced by the threshing machine.
Flatlands demand a vertical structural articulation; mountains, a horizontal one. The work of man must not attempt to compete with the hand of God. The Hapsburg watch tower disturbs the skyline of the Viennese Woods, but the Husarentemple harmonizes well with it.
Do not think about the roof, think about rain and snow. That’s how the locals think, and so they build the flattest roofs they can using the know-how they have. In the mountains the snow must not slide when it wants to but when the locals want it to. The roof should be safely accessible for shoveling away the snow. We also have to create the flattest roof possible using the know-how and experience at our disposal.
Be true! Nature only tolerates truth. It copes well with iron truss bridges, but rejects Gothic arched bridges with turrets and defensive slits.
Have not fear of being chastised as outdated. Changes in the old building techniques are only allowed when they mean an improvement on them, otherwise remain with the old. For even if it is hundreds of years old the truth has more connection with our innermost feelings than mendacity, which paces alongside us.
