太田市美术馆图书馆丨日本群马丨平田晃久建筑设计事务所

项目坐落于日本群马县太田市车站前，是一座集美术馆与图书馆为一体的文化交流设施。项目的核心理念旨在打造一个文化目的地，利用该设施振兴基本已经荒废的车站前地区，将人们重新吸引到该场地中来。设计的另一个核心目标则是将建筑内部与城镇联系在一起，为人们营造出一处轻松亲切、可以随意拜访停留的休闲场所。

This cultural exchange facility was built in front of Ota Station in Gunma Prefecture. One aim of the project was to create a base that would draw a stream of people back to the front of the station, which had become largely deserted. Another aim was to create something that would make a connection between the town and the building’s interior, encouraging people to casually drop by.

建筑设计旨在彰显出太田市独特的地域特征，设计灵感来自飞机机翼与螺旋桨，旨在向曾是该市工业中流砥柱的中岛飞机公司致敬。设计师希望将该建筑打造成城市中重要的空间节点，让人们与活力如河流一般汇聚于此。

It was also necessary to create a place that was wholly unique to Ota. Using the image of a wing and propeller, a reference to the Nakajima Aircraft Company, which had once operated in the city, I attempted to evoke a state in which the building would serve as a node for multiple streams.

从结构上看，一条钢架斜坡环绕在建筑周围，将五个钢筋混凝土盒子包裹在其中。这种建筑形式能够让人们自然地走到每一层楼，就像在城市中穿行一般。此外，设计师还力图将具有不同特点的场所整合在同一三维空间中，让不同年龄、不同背景的人都能寻找到属于自己的位置。

In concrete terms, I proposed a structure in which a slope would wind around and around five reinforced-concrete boxes by means of a steel rim. This enables people to naturally make their way to every floor as if they were walking through the city. In addition, I tried to create a three-dimensional symbiosis of places with a diverse range of characteristics to enable people of many different ages and backgrounds to discover their own place.

从外观上看，大面积的玻璃将建筑内部的书架与艺术品暴露在人们的眼前，吸引着人们走进室内探索，美术馆与图书馆之间存在紧密的视觉联系，同样起到了引导人流的效果。

The book shelves and works of art are visible through the window, making people want to go inside, and in the same way that a museum or a library exudes a welcoming air by providing us with a glimpse of its contents, the building precipitates a stream of people.

这座建筑就像绽放在车站前的一朵花，吸引着大量的当地居民与工作人员参与其中。

Designed to entangle a large number of local residents and staff, the building is like a flower that was born in front of the station.
