| Abstract |
This study analyzes the effects of special provisions through cases of building agreements and examines how these provisions contribute to
achieving policy objectives. First, regarding development conditions, the integrated application of the Relationship with Land and Roads
standard was found to effectively expand developable areas by improving the conditions of isolated or irregularly shaped plots. Second, in
terms of functional efficiency, sharing boundary walls between adjacent sites through building agreements reduced the number of required
stairwells or cores. Each stairwell or core consequently gained approximately 23 to 86 percent more usable floor area compared to before the
special provisions were applied. The integrated placement of stairwells also enhanced spatial utilization, resulting in an overall increase of
about 10 percent in total floor area. Although the integration of parking lots had little or no impact on parking capacity, it improved vehicle
circulation conditions. Finally, in terms of economic efficiency, the integration of sewage treatment facilities reduced the number of
installations by half and shortened sewage pipe lengths by approximately 30 to 60 percent, thereby minimizing the extent of related civil
engineering and ancillary works. |
