These historical "Red Brick Warehouses-Yokohama" were constructed between 1911 and 1913 as a symbol of the modernization and development of Yokohama. In 1994, work began on the restoration and revitalization of the buildings. After eight years, the valiant figure of these buildings, which stood during the Great Kanto Earthquake, the Second World War, and the occupation and withdrawal of American troops after the war, has risen once again. Now, Building 1 is being used as a multipurpose space and hall, and Building 2 is being actively used as a commercial building with 31 tenants. The work, not only for restoration, but also for revitalization of the buildings, was undertaken in stages. With the restoration work, from the standpoint of the conservation of cultural treasures, while making as much use of the original as possible, advanced technology was also used, including earthquake resistance strengthening work, and repair work to the exterior walls and roofs. Furthermore, with the revitalization of the building, various methods were used to create a functional space conforming to present-day laws and standard, while maintaining the atmosphere of these historical structures. Being able to be used, and being pleasing to the eye at the same time, this attempt at giving new life to these historical structures is a pioneering example of how restoration can be done to historical buildings while enabling them to be revitalized.
