<p> In the planning and design of shared space for a senior citizens' living facility, the elimination of blind spots helps caregivers to watch over users, but users do not feel comfortable. On the other hand, privacy makes it difficult for caregivers to watch over them.</p><p> Thus, there is a trade-off between nursing care and living in the shared space of housing for the elderly, and it is necessary to resolve the conflicting demands of the nursing care side and the resident side. Then, what kind of floor plan we should use to realize a space where caregivers can watch over the caregivers and users can spend their time calmly and comfortably?</p><p> We aim to plan the shared space of the housing for the elderly in consideration of both caregivers and users.</p><p> Specifically, we transformed the plan form of the shared space and created several candidates. The visibility of each is described by the visibility analysis (mainly isovist analysis), discussing what is the appropriate visibility in the shared space, and showing the plan with more appropriate visibility.</p><p> The findings of this study are as follows.</p><p> 1. Based on previous studies, we summarized the appropriate visibility of shared spaces for users as (i) "being able to hide from the view of others" and (ii) "small scales close to residences" and expressed them as quantitative visibility.</p><p> 2. We summarized the visibility of shared space appropriate for caregivers from previous studies as (iii) "having at least one place where you can see it" and expressed it as quantitative visibility.</p><p> 3. We proposed the following methods for planning and designing based on visibility. 1) Setting the floor plan model. 2) Enumeration of the combinations of segments. 3) Selection of an appropriate combination of segments by examining the visible amount in frontage width and overlap width. 4) Decision of the variables of the constraint. 5) Reduction of combinations using the cumulative probability of visible quantities. 6) How to select a solution.</p><p> 4. We obtained the combination of effective segmentation for the floor plan model. As a result, we found that the shared space with appropriate visibility for both the caregiver and the user was neither unsegmented nor maximally segmented. It was an adjustment of the positional relationship and frontage distribution with moderate segments such as 2 and 3 segments.</p><p> 5. In order to plan a space that enables ones to hide from the view of others, it should split into LDKs with different floor plan dimensions. We aim at a space with various visible quantities by making the visible quantities closer to a uniform distribution.</p><p> 6. In order to provide a sense of scale close to that of a house, it is advisable to prepare the LDK part with a small frontage in the Positional relationship not too close and not too far apart with other LDK parts.</p><p> 7. In order to create at least one place where there is a view, it is better to create a large-sized portion of LDK or layout separate LDK in overlapping positions.</p>
