The Tokyo station Marunouchi building, designed by architect Kingo Tatsuno, opened in 1914, attracting many people with its majestic figure. However, in 1945, its domes in north and south, roof and interior decorating was destroyed by the bombardment. After the war, the three-story-building was restored into the two-story station, remaining until 2007. In this “preservation and restoration project”, the original appearance is faithfully restored as well as functional extension is made including new building frame under the steel-frame brick building to inherit this historic value to the future. The seismic isolation method is used to allow the building to withstand a giant earthquake.
