In Japan, housing featuring 6 floors or more is considered high-rise housing and in such cases it is required by law to install elevators. Most residential construction erected between the 1960’s and 1970’s features less than 6 floors and is without elevators. For residents of such housing living on upper floors it is a physically strenuous task to reach their living quarters and it is precisely for this reason that the rate of vacancies in such buildings increases, especially with an ever increasing aging population. Meanwhile, also the aging of the buildings them- selves is becoming another significant problem. However, all these problems can be solved by deciding on an “Assembly Precast Concrete Elevator Shaft” which is introduced in this article.
