The general direction of the regeneration of the old city center has been focused on low-density, culture-oriented and residence renewal. The ‘low density’ means to keep the population below the current size by employing low-rise buildings. The ‘culture-oriented’ means to rule out commercial and/or industrial development by setting up a culture zone that is full of cultural facilities. The ‘residence-renewal’ aims at improving the residential performance by way of remodeling the residential buildings without the expansion of the residential area. These directions appear persuasive but there is no reason to set aside all the other considerations. On the other hand, we will address an alternative way of regenerating the old city which is focused on the high density, industry-oriented and mixed-use development.
