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.

We strongly believe that the field of (urban) design should not simply adhere to these standards as some neutrally existing context but should actively engage in discussing them in order to make them subject to design as well. read more

Ridge Line Protection

Hong Kong

In order to allow the city to remain visibly a settlement at the edge of mountainous terrain, the ridgeline of the mountain range is protected. The city has the discretion to determine the number of meters of ridgeline that must be visible from the harborside lying opposite.

  • The visual importance of Hong Kong’s ridgeline.
  • View corridors across Victoria Harbor to protect a 20% offset of the ridgeline.
