设计亮点

建筑形式简约而富有表现力，室内外空间流动且互动，绿植屋顶为社区带来活力。

该多媒体图书馆位于一片住宅区的中心，建筑师将所有功能融合在一个单体建筑中，为人们争取了更多的绿地。新建筑的二层向外出挑，宛如漂浮在空中，结构裸露在最外层。

该建筑形式非常简单，但是具有强烈的表现力。

一个巨大的挑檐作为建筑一层入口的门廊。一层有门厅，演讲会报亭，办公室。二层是阅读区。一层和二层之间的夹层是多媒体区。主要的阅览空间分区简明，两侧的透明窗户为图书馆引入光线，半透明的天窗为阅览区带来更多的自然光。建筑天花结构是起伏不平的，这造成阅览空间的高低不一致，并影响到楼上的屋顶花园，最终的绿植就像起伏的绿毯。这个屋顶可以被周围的建筑看到，因此非常重要。

The Romainville multimedia library is located in the heart of a dormitory town that is being completely renovated. The town planners wanted to open up the district by fragmenting the housing blocks, creating a central plain to provide a large park and two facilities, including the multimedia library which is intended to act as an attractive magnet on a neighbourhood level.

The new building floats between two flying carpets. Following a continuous movement, the multimedia library’s volume sweeps over the level of the street and the public garden to slide under the gentle slopes of its planted roof.

It is the project’s roof that gives the initial driving force. The roof’s hills and valleys transmit the sweeping movement through to the level of the central plain, crossing through the large reading room on the upper floor. This is achieved by the negative curves reflecting the undulating movements of the roof through to the ceiling. As well as traversing, the oriented interior space of the reading room overlooking the street and garden is also traversed and suspended by the landscape as it rises up to become the ceiling.

The new media library at Romainville can be seen as a building with simplearchitectural forms, but with great power and expressive richness. It is a building‘oriented’ between the new street and the large redesigned garden. It is a building‘hierarchized’ on the basis of 3 superimposed horizontal sequences: a base on theground floor, a large metal covered hall on the first floor cantilevered on both thestreet side and the garden side, lastly a topographically undulating vegetated roof.

These three main elements structure and bring together the building’s architectural and functional image. The project is no more extensive than the surface area of the plot proposed in the overall development plan, thereby freeing up the largest possible area for the future garden. The main volume is aligned with the new street, but the ground floor recess under the first floor cantilever is an opportunity to lay out a vast covered, sheltered passage between the public roadway and the media library. The building takes its characteristic appearance from the first floor metal structure’s extensive columnless overhang. On the street, the monumental awning opening onto this big covered area naturally signals the entrance to the building. Some powerful architectural sequences accompany the user or visitor from the outside right into the heart of the media library: the parvis under the awning, the exhibition hall, the vertical link space with the grand staircase, from where you come to the main reading room. Finding one’s way around is facilitated by the large north-east and south-west windows facing each other like a pair of indoor-outdoor bookends. Another powerful feature of the reading room is its ceiling, which follows the underside of the undulating vegetated roof. The very fluid crossing space is also set in movement through the random shapes of the ceiling, contrasting with the straight frontage walls.

A second mezzanine floor houses the multimedia area: on the ‘Russian doll’ principle, this area readily accessible from the adult and children’s sections hovers slightly above the rest of the browsing areas for reasons of soundproofing, while remaining highly visible and attractive from the central area. The two glass frontages are picture windows looking onto the city or the garden through the filter of the exterior metal structure A maintenance area midway between the glazed façade and the structure gives depth to the casing. This depth is used to install the outer blinds protecting the reading areas in conditions made to last. Circular translucent skylights nested in the roof bring extra light to the central area, while providing smoke ejection from the interior volume. The green roof is treated as a natural but hanging extension of the future garden. Its topography lends it a different status from the ordinary vegetated terrace roof. This roof can be seen from neighbouring buildings, and we feel it is very important that it blends in with the future landscaped area. The inverted impact of its undulations is a key element in characterizing the atmosphere in the large reading room, and evidences the determination for this project to be highly consistent, with continuity between the work on the interior spaces and the handling of the exterior architecture. The metal structure featuring like a grid around the first floor, and the cantilevering over the ground floor areas are the other main examples of this.
