Long House with an Engawa Senior Daycare Center | Yamazaki Kentaro Design Workshop
Long House with an Engawa Senior Daycare Center, Remembering What We Have Forgotten Through Architecture | “Long House with an Engawa” is a senior daycare center. The client, Mr. Ishii, is a caretaker who practices a style of care that allows people to live their lives normally, even with severe conditions like dementia. In designing this project, the goal was to create an environment in which aging is not considered isolated from everyday life, even with dementia or another disability.
The site is long and narrow in the north-south orientation, and the building area was limited by regulations for building over cliffs. Despite the unfavorable conditions, we decided to lay a 2.5-ken (4.55 meters) wide veranda-like floor in a straight line welcoming the community with the main wooden structure and an open veranda that can be accessed in various ways. The building contains outdoor spaces with three main functions: a café and workshop for local residents, a “living room” for the elderly, and a tatami room and bath that echo a traditional hanare (detached room). Small walls and volumes were inserted to counterbalance the monumental structure, creating a scattering of small but human-scale spaces.
Particular attention was paid to designing the boundaries between the inserted architectural elements–the windows. For example, a daybed was placed by the window between the café and the terrace, and the dimensions, fittings, and materials were selected so that people could rest their bodies in the nooks, creating an “ikata” (mode of being in place) that allows people to spend time with others even if they are by themselves.
With the cooperation of local NPOs and Mr. Ishii’s company, this building is set to become a place of belonging for many people. We all hope that it will become a safe space for single-parent families in the neighborhood who need help, or for children who are not attending school. Connections are beginning to form between the elderly, the disabled, children, and other neighbors who gather here.
In order for the facility to integrate gradually into the community, the garden pond and bamboo fence were created with the cooperation of local residents. Through the lively workshop, we were able to catch a glimpse of how people from all walks of life might share their time in this place. The architecture resembles a bridge or a temple. Watching the people sitting on the porch enjoying their onigiri (rice balls), it feels like this architecture is a reminder of something important that modern Japan has lost.

Born and raised in Ukraine, she holds a Master’s degree in Languages from Taras Shevchenko National University of Kyiv. Her deep passion for architecture and visual storytelling led her to transition from translation and editorial roles into the world of design media. With a keen eye for conceptual clarity and narrative structure, Anastasia curates and presents global architectural projects with precision and flair. She is particularly drawn to parametric and digital design, cultural context, and emerging voices in architecture. When I’m not analyzing the latest architectural trends, you’ll probably find me searching for hidden gems in cityscapes or appreciating the beauty of well-crafted spaces. After all, great design—like great connections—can be found in the most unexpected places. Speaking of connections, because architecture isn’t the only thing that brings people together.
