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。

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.

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.

“改造后的Palais du Commerce商业大楼不仅会成为当地地标，还会成为催化剂，将整个地区转变为受人欢迎的目的地。”MVRDV创始合伙人Nathalie de Vries说道，“我们的设计尊重建筑历史，并且放眼未来，帮助雷恩实现对城市未来的规划。加建的部分极具现代感，将成为建筑历史上崭新的一页。”
“Not only is Palais du Commerce a local landmark, but its transformation will turn the Place de la République into a popular destination and act as a vital catalyst for its surroundings”, says Nathalie de Vries, founding partner of MVRDV. “Our design approaches this task with an appreciation of the building’s history, but also with an eye towards the future, helping Rennes to achieve its urban vision. The additions that we will make are clearly modern in character, clearly showcasing this design as the latest chapter in the building’s storied history.”
The 18,000-square-metre project – which includes 12,000 square metres in the existing building and a 6,000-square-metre extension – introduces new shops, a hotel, offices, a coworking space, a variety of leisure spaces (including a LEGO museum and event space and an electronic music bar), and a school for the kitchen and hotel industry led by chef Thierry Marx.
The most striking exterior change to the existing building is the addition of a grand, winding staircase at the centre of the façade, a tongue-in-cheek reference to the fact that the original building did not have the elegant foyer space or other spatial centerpiece typically found in such grand buildings. This addition also serves a very functional role in the new layout: on the second floor, a welcoming reception area sets up a path through the building’s upper levels.

The extension, on the eastern end of the building, comprises a wood construction that imitates the forms of the original building while adopting a modern architectural expression, with a façade of black textured ceramic and opaque glass panels which references the black slate roofs of the Palais du Commerce and other buildings in the city centre. This will be respectfully connected to the existing building by a glass gallery that, like the passage through the Palais, offers permeability at street level. Inside, a second winding staircase connects the route through the building’s second floor level to the new entrance on Place de la République.

The new design makes the most of invisible methods to intensify the building’s usage. The basements of the building will not only be used more effectively, but will be extended underneath the Place de la République to create more floor area. The roof will also be occupied, with a bistro included in the building’s central dome that takes advantage of the existing atmosphere of the dramatic structure. The spaces between the different roofs will be opened up to create a continuous passage from one end of the building to the other, with the gaps between the roofs and the dome covered with glass, so that the original skyline of the building is maintained.
