MVRDV赢得了雷恩Palais du Commerce商业大楼翻新及扩建项目竞赛优胜。MVRDV将与Bernard Desmoulin合作，对这座18000平米的雷恩地标性建筑进行改造，让建筑和周边社区重获新生。设计方案将把这座曾经的公共建筑转变成城市主要商业街，提升项目在公众生活中的重要性。

MVRDV has won the competition to renovate and extend the historic Palais du Commerce in Rennes. Developed alongside co-architects Bernard Desmoulin for developers Frey and Engie Avenue, the 18,000-square-metre redevelopment of the notable Rennes landmark will signify a renaissance for both the building and its surroundings. MVRDV’s proposal will reactivate the Place de la République and turn this former public building into a centrepiece of the city’s main commercial street, raising it to the level of significance that was initially intended.

Palais du Commerce商业大楼位于雷恩市中心南部，经过当地建筑师Jean-Baptiste Martenot 和Emmanuel Le Ray在1885年和1929年两次建设，曾作为邮局、图书馆和艺术学校使用。如今这栋建筑和当地居民的生活严重脱节，MVRDV希望通过这次改造和扩建为建筑增添新的功能，让它重新成为城市生活的一部分。

新的建筑尺度宜人，成为了人们消磨时间的好去处。在市政部门协助调整巴士运营的努力下，建筑师将大楼南侧的街道改造成了一片景观台地，并且可以部分和Vilaine河产生联系。

Located in the southern part of Rennes’ city centre, the Palais du Commerce was originally constructed in two stages between 1885 and 1929 as a post office, library and arts school by local architects Jean-Baptiste Martenot and Emmanuel Le Ray. Today, the building is poorly integrated into the life of Rennes, with most residents unaware of most of the activities inside. The renovation and extension designed by MVRDV aims to rectify this, activating the building with new uses and a design that communicates these new functions to passers-by.

On the urban scale, the scheme will favour pedestrians and transform the Place de la République into an inviting public square in which to spend time. Alongside the efforts of the municipality to reorganize the bus network, the project plans to convert the Rue du Pré Botté, on the Palais du Commerce’s southern side, into a landscaped pedestrian area animated by terraces. The proposal also recommends the partial re-opening of the cover of the river Vilaine.

设计在尊重建筑历史特点的同时，增强了它的透明性。原本的窗户被巨大的玻璃板替代，一层拱廊中设置玻璃店面，为商业单元提供了更多空间，并且保留了拱廊曾经的视觉效果。

The design is respectful of the existing building while taking a critical approach to its drawbacks. A key approach was to increase the building’s transparency: windows will be replaced, with larger panes of glass giving improved visibility. Meanwhile on the ground floor, glass storefronts will be added in the arches of the arcade in order to provide more space for the commercial units. This alteration is designed in such a way that the visual effect of the arcade is preserved, as the walls introduced into the arcade separating the different shop units will also be glass.
