Tokyu Hospital in Tokyo, Japan is an example of a hybrid building that combines functions that normally don’t mix. In this project, a hospital is combined with a railway station. A very complex technical design process became the core of this project. It was necessary to prevent the hospital from electromagnetic radiation and vibrations produced by trains. The application of an ingenious spring construction and the use of silicones prevent the hospital against disturbance. Another advantage of this rare combination of functions is an improved accessibility and reach ability for polyclinic patients. In a city where everybody is moving by train, this hospital is easily localized.
The initiator of the project was the Tokyu Railway company. In Japan it isn't exceptional that a private railway company owns large public, commercial real estate, like warehouses, supermarkets, hotels and in this case a hospital. Due to the urban context and the high density, it was impossible to rebuild the hospital on the former location, so they felt forced to this technical challenge. Yasuda Koichi Laboratory + Atelier has been responsible for this design, which was delivered in 2007. The development of this hospital fitted in the policy of the municipality of Ookayama, a district of Tokyo. wants to become sustainable urban environment. In the design the architect, Yasuda Koichi,, used the authentic situation of Ookayama, known for its beautiful green hills was taken as a source of inspiration.
