Kabuki-cho is the most prominent entertainment district in Japan. There are many multi-tenant buildings which have bars and restaurants within. But today, Tokyo metropolitan government wants to clean up this area and redevelop some old theatre. My diploma project is redevelopment of one of the biggest theatres in Kabuki-cho.

In Kabuki-cho, there are very interesting characteristic spaces. There are many narrow paths and gap spaces between small buildings. These small and narrow spaces are almost private property actually, but for us visitors, these are not private but public space like a western plaza. So, I focused on these types of spaces in Kabuki-cho and designed a big commercial complex referring the gap spaces.

In Japan, a void space must be needed in almost all of premises from a legal perspective. And the original land readjustment plans relatively small sites so lots of people can own in Kabuki-cho. That is why there are so many gap spaces in Kabuki-cho.

There are many equipments such as emergency stairs and piping equipment in  the gap spaces. These equipment support not only buildings which are attached but also a city working well. So I think these gap spaces act as infrastructure spaces in the city. 

The skyline of Kabuki-cho are made by various height of buildings. As we can see from this graph, there are some distinguishing classes of height of buildings. Spaces above buildings connect the gap spaces three-dimensionally, those spaces become “urban voids”.

Firstly, I plan gap spaces following the gap spaces around the site. And these gap spaces I planned will be public space for this building.
