Grand Urban Rules

Design Rules and Design With Rules!

Cities as cultural products are neither ‘built’ nor ‘planned,’ at best they are guided and steered in a certain direction. Therefore, rules and regulations are one of the few tools that are actually suitable to guide future development within such collective and complex urban settings.

Bulky Block Type

New York

Economic pressures compel the utilization of a given building lot all the way to applicable legal limits. These limits then determine the building’s form. If a building is constructed which, despite all restrictions, fails to have the desired appearance, then the city has the authority to determine the proportions / shape of its volumetry by means of additional regulations. The utilization coefficient, however, remains constant.
