Study On Rebuilding of Non-conformed Condominium Apartments using Reconstruction from Earthquake Disaster-type of Design with Comprehensive Consideration System

Evaluation from Applied Conditions and Actual Rebuilding and Open Space Situations

Abstract

Many of the condominium apartments near to rebuilding stage can be rebuilt only under the existed floor area, because they were built exceeding current FAR regulation. They are called “existing non-conformed condominiums.” In the case of Great Hanshin-Awaji Earthquake Disaster, “Reconstruction from Earthquake Disaster-type” of “Design with Comprehensive Consideration System” was temporarily and exceptionally introduced, to encourage their reconstruction.
This study aims to evaluate this system, by analysis of conditions, and actual rebuiliding and open space situations of the applied condominiums. The results were the followings. 1) Most of the condominiums were rebuilt near to the previous floor area. 2) The significance of the large coefficient of extra FAR is in relieving the difficulties to create Open Space for Public, within the comparatively small and complicated building sites, to secure extra floor area. 3) The forms of the buildings have change to tall and slender ones.
