Installation of nursing room is promoting the introduction of public facilities as well as local commercial facility.In this way,nursing rooms are spreading rapidly,but there are no clear design guidelines at this time.Therefore,in some cases it cannot be said that a user can use comfortably necessarily.In this research,to show the design guidelines of the nursing rooms that can be used comfortably accompany infants,by field survey,and to understand the arrangement of the building,zoning nursing rooms,to clarify the issues of architectural planning of the future it is intended to make.The survey,were selected by focusing type of building that is located nursing rooms of Japan,for the indoor environment and the area of the nursing rooms.In commercial establishment or a public facility,from the form of the indoor passage,it includes excursion-typed,main-street-typed,connection-typed,and complicated-typed,in addition classified.Next,survey analysis was conducted about the spatial relationship with a transportation of the upper and lower,an entrance,and a toilet and circumference environment sides of a nursing rooms and a building.Moreover,about the zoning in nursing rooms,the zone division was carried out and it analyzed for every area.In this research,the following results were obtained by the field survey about the flow line to the nursing rooms which an infant accompany uses well,the passage form of a building and the arrangement in a building,and circumference environment.The nursing room is not concerned with the scale of a building,or the passage form in a building,but is arranged at the place which adjoined the toilet not in the center in a building but in a corner of the building in many cases.The nursing rooms are located from an entrance,an elevator,etc.of a building in a distant position in many cases.The flow line up to go to the nursing rooms,that it is allowed to detour a route that bent many times in many cases.That segmentation of space of each zone of the nursing rooms is ambiguous in many cases.The breast-feeding zone of nursing rooms is located at indoor back in many cases.It separated the breastfeeding zone is a curtain in many cases,there is a problem from the point of view of privacy.By this,the actual condition of the deployment planning of the nursing rooms in this time has been grasped,the subject on future architectural planning was able to be clarified,and the design guideline was able to be shown.
