Since rapid growth in population, living space in Tokyo has become scarcer and prices have gone through the roof. The high density of the city requires people to live in very small spaces. Due to the trend of single households, many solitary-living people pay the price of isolation and social alienation. In addition to the housing shortage, it is paramount to consider the geographical location of Japan. Situated on the Pacific Ring of Fire and near four major tectonic pla-te boundaries, Japan has a history of earthquakes and seismic activity . Earthquakes cause severe destruction and human suffering, and the consequences force many people, who have lost everything, to live in emergency accommodation during the time of reconstruction. The focus of the sky scraper, situated in the Chiyoda ward in the heart of Tokyo, is on the integrated "Vertical Share House", which provides a favorable living alterna-tive within the city. Due to the large number of diverse shared spaces the building offers, it stands out from simple residential communities and is attractive to diffe-rent target groups. During emergencies the Share House and the hotel can gradually be converted into emergency accommodation for up to 1,850 people. Through the recompression of each room, the high rise can accommodate and house up to three times the number of people as under normal circumstances. The seismic safety of the building is essential. Even in the event of a strong earthquake, the skyscraper should remain unscathed. The adaptation of the design and structural dynamic calculations guarantee the stability of the building in case of an earthquake.
