JA Kyosai Hirakawa-cho Residence

This is an office and rental condominium complex and is the base for the JA Group mutual aid business. Aiming for a symbol tower for the Japan Federation of Mutual Aid Cooperatives (JAFMAC), the building was designed with the concepts of “a formidable stance,” “a safe and reliable configuration,” and “an expression of reliability.” A building with emphasis placed on environmental performance, and with good earthquake-resistance and disaster-prevention performance has been realized. Furthermore, the building has been designed to be in harmony with the local residential area and suit the town planning.

WASEDA University Building 40
 |
This building houses various research and testing facilities centered on the development of extremely low power consumption IT technology, towards the realization of a low-carbon society. The objective was the fusion of a clear architectural structure and environmental technology using unit laboratories fitted out with the required infrastructure in each span. The 360 vertical axis rotating louvers covering the exterior walls are used to control the “external environment,” such as for privacy, natural lighting, and warmth, and are also used for the “interior space,” such as a projector or display screen. Changing the angle of the louvers, which can be freely turned, changes the iconic image of the complete façade. With the aim of reducing LCC, by designing a logical structure using modules and a dry system, the functionality and flexibility of the building is high, realizing long-life, cutting-edge laboratories.

This project called for the reconstruction of this medical treatment and convalescent hospital which had become dilapidated. With the aim of improving the quality of life of the patients, ranging from chronic to terminal, the building has been designed with a natural Japanese feeling. Glossy grey tiles have been used for the exterior, and shadows have been created by using balconies with deep eaves. Patients can feel the light and wind inside the hospital rooms, and the layout has been designed so it is easy for the staff to nurse. The building has a rooftop garden and family meeting rooms, designed to assist family visits. With an art deco base tone interior, the selection of well-poised furniture and small articles from the early Showa Period, the space has a sense of nostalgia.

Jodo Shu Head Temple Chion-in Wajun-Kaikan and Approach

This project involved the reconstruction of the congregational hall and maintenance of the approach of this temple as work commemorating the 800th anniversary of the death of Saint Honen. Based on the teachings of Jodo Buddhism, the aim was for harmonious coexistence between nature and society. A public environment has been created linking the Higashiyama mountain range with the square in front of the main gate, Sanmon, which is a National Treasure. Making use of the sloping site, light courts and bubbling streams have been constructed, and light, wind and water have been drawn into the under ground floor. The building has a neat exterior appearance, with a hipped roof with tiles, and plaster. Also, the interior makes use of the building materials, befitting the guest house of this historical and famous temple. As well as the accommodation function, the building can also be used as a big hall or a gallery. At the same time, work to give rebirth to the historical approach was also carried out.
