The purpose of this paper is to report the reconstructing process of a existing non-conformed department store. Some results show as follows:
1) The problem of “building restrictions on roads” is solved by “substitution of road” and “city planning decision” which secures passage way.
2) As for the problem of existing non-conformed building, “excess of floor area ratio” and “incompleteness of escape stairs” are solved by treating exisiting building and extention building as a whole, although “lack of smoke exhaust equipment” is solved by targeting only in an existing building.
3) The contents of this case is not authorized under the present law by reason of the revision of law. In this case, it was possible because submitting the confi rmation application is just before the revision of law.
