| Abstract |
The continuously increasing number of the 1 or 2-member-households causes sharp increase of the small single-room apartments. However, because to the middle and large apartments and the small apartments, the same standards of noise insulation are applied when building them, it is true that the possible problems between housing units cannot be resolved. Also, the residence culture is under the change at the moment from the multi-room to the single-room residences. However, the small apartments are dividing the units with single walls which are not consistent with the reality. So, the residents suffer from infringement of the right of comfort occurring between neighbor house- holds. The results from this study are expected to be used as an elementary material for making policies regarding the party walls between the housing units and for designing the small apartments and a reference for studies of the general information users, such as operators of buildings. |
