note: main building
An urban square mostly is familiar by its main building or landmark, and in 1889 Camillo Sitte defined a natural law between the characteristics of the building and the square. He defines two categories of city squares: the deep and the wide type. Whether a plaza is deep or wide usually becomes apparent when the observer stands opposite the major building that dominates the whole layout.
At a wide square the main building is positioned at one of the long sides of the square. Usually, the building is wide as well and not so high. In another manner of thinking: when the main building is positioned at a long side, the building should be wide.
At a long square the main building is standing at the top of the square at the short side. A building on this position should be small and higher than the other buildings. When the building stands on the opposite side of the main route, the landmark functions as a natural anchor to attract pedestrians.
– Out off the theories and analyses from this site I formed some notes with my own perspective on urban squares to help making choices at designing them.
