note: basic shape
Sitte claims that an urban square with a triangle shape is unbearable. At such a square the irregularity becomes awkward and people feel unpleasant, because they won’t have a good overview. At a shape of a geometric square people will get disoriented.
The absolute minimum proportion between a squares width and length is 1:1¼. The maximum proportion which still will be experienced as a enclosed spot is 1:3. Basically, this forms a rectangular square. Sitte abominates the ‘perfectly rectangular modern plaza that’s laid out with a ruler and is only ever-so-many square yards of empty surface’. So, it’s case to make its basic shape as well as its edges irregular.
He encourages the clustering of plazas above one big square.
– 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.
