Gate Tower Building is a 16 floor office building in Fukushima-ku, Osaka, Japan. It is notable for the highway offramp at Umeda Exit that passes through the building.Gate Tower Building is just one of the many highlights you can arrange to see using our custom trip planner, Osaka Edition.
The building has a double core construction, with a circular cross section. The Umeda Exit of the Ikeda Route of the Hanshin Expressway system (when exiting the highway from the direction of Ikeda) passes between the fifth through seventh floors of this building. The highway is the tenant of those floors. The elevator passes through the floors without stopping, floor 4 being followed by floor 8. The floors through which the highway passes consist of elevators, stairways and machinery. The highway does not make contact with the building. It passes through as a bridge, held up by supports next to the building. The highway is surrounded by a structure to protect the building from noise and vibration. The roof has a helipad.
A wood and charcoal business held the property rights for this plot of land since the early Meiji period, but the gradual move to other sources of fuel resulted in the deterioration of those company buildings. In 1983, redevelopment of the area was approved, but building permits were refused because the highway was already being planned. The property rights' holders refused to give up, and negotiated with the Hanshin Expressway corporation for approximately five years to reach the current solution.
Although normally highway corporations purchase the land they build a highway on or over, it is not guaranteed to succeed and therefore issues like this can arise. For that reason, the highway laws, city planning laws, city redevelopment laws and building codes were partly revised in 1989 to allow the unified development of highways and buildings in the same space. This system was originally designed to facilitate the construction of the second Ring Road in the vicinity of Toranomon, Minato-ku, Tokyo, but in the end was not applied there. Instead, the system was put into effect in the construction of the Gate Tower Building, becoming Japan's first building to have a highway pass through it. Normally, highways are still built underground in these cases, and passing through a building is an extremely rare occurrence.
Gate Tower Building Reviews
大阪の都市高速をバスに乗って眺めていたら、いきなりビルの中に道路が延びててビックリします。こういった建物も、限られた都市の空間を有効利用する視点では良いのかもしれませんね。 more »When I was looking at osaka's city expressway by bus, I was surprised to see the road suddenly extending into the building. These buildings may also be good in terms of making effective use of limited urban space.
Well, this in one of the few things on the city that caught my eye and I had the chance to see it from the train from Nara (sit on the right side) still not sure if there is a “viewing point“ for it, more »
