项目简介
Presentation du projet

项目位于城市中心一座学校的操场上，操场本身有一定坡度，新建筑顺着斜坡建造，与位于较高位置的校舍相连。人们可以通过南侧开向街道的大门进入基地，从这里他们可以看到建筑的全貌。其形态舒展，表现了它作为舞蹈中心的功能。建筑的立面使用白色的手制砖，与周边奶油色或米黄色的楼房相协调，自然融入了石头色的环境之中，同时因其独特的体量和自然的材质而显得卓尔不群。波浪般倾斜起伏的屋顶上覆有白色的釉面瓦，在阳光下变幻着色彩，如同一座舞动的雕塑。

The project is located at the heart of a city block in a school playground. The new volume extends an existing school building up the slope of the passageway that leads onto the site, and settles itself onto the playground’s sloping surface. The building is accessed from the street by passing through a porte-cochère that opens onto a passageway. From here the southernmost end of the building can be seen in all its verticality. This stretched volume signals the presence of the dance centre. The building’s pale facade of hand-made brick fits well with the creams and beiges of the neighbouring buildings. Rather than breaking with the context, the building fits into the existing stone-coloured environment, at the same time underlining its own presence with its eye-catching volumes and natural materials. Surrounding homes look over the steeply pitched roofscape with its glazed white tiles, a dancing sculpture of changing colours as sunlight plays across the undulating dance studio roofs.

建筑的位置和体量
New building : location, organisation, composition and volume

项目从Lully学校校舍的墙面延伸而出，顺着倾斜的地形设置，替代了学校操场上曾经的有顶空间，侧面与入口通道相接。项目的尺度与城市建筑相协调，但其独特的造型让它在街区中显得十分出众，无论是从周边的公寓还是从操场入口的通道看向这座建筑，都会被它的形态吸引。建筑的檐口限高为九米，边界与已经拆除的长方形有顶空间相同，为29米x13.45米，在可建设面积的限制下，建筑内的空间布局相当密集，以满足建筑面积的要求并容纳所有需要的功能。为了让新建筑与周边的建成区域更加融合，建筑师在视觉上打散了其巨大的体量，并且充分挖掘了高密度下建筑的节能潜力。

建筑最主要的概念是尽可能地去强调它的垂直感。舞蹈教室拥有两个巨大的屋顶，使它们在整个建筑中极为突出。尽管建筑在高度上和现存的建筑相一致，并与周边环境保持协调，但它与众不同的造型还是吸引了大量的目光。最高和次高的屋脊距地面分别为14米和12.4米，为了防止对原有建筑的视线造成阻挡，第三个屋顶体块高度较低，将新建筑和Lully校舍联系在了一起。

The project replaces a covered section of the Vauban school playground. The building’s volume extends the line of the existing walls of the Lully school building, flanking the entrance passageway at lower and upper ground floor levels. Following the slope of the path, it settles onto the incline of the school playground. The project does not impact on an urban scale, but rather on that of the city block: from the surrounding apartment blocks who have plunging views down onto it, from the entrance passageway and the Vauban playground. Organization, composition, volume:  The available buildable area and the required surface area have generated a very dense building volume. The project fits into the site’s constructible area. The eaves are under 9m (7.5m). The building’s footprint (29m x 13.45m) is approximately that of the demolished rectangular covered playground area. The potential energy savings of this density have been exploited, whilst the volume’s massiveness has been visually broken down to lighten the building’s presence in this built-up area.

The main architectural principal here was to highlight the building’s verticality as much as possible. The dance studios are visible within the overall volume of the extension with their two large roof spaces. The building fits into the context with an average height in relation to its neighbors. Rather than breaking with the context the building fits well into the existing environment, while it uses its volumetric presence to draw the attention. The highest roof ridge rises to 14m from ground level and the second highest to 12.4m. The third roof volume links the extension with the existing Lully building. It is lower to avoid blocking views from rooms in the existing building.

颜色和材料
Colours and materials

周边建筑的颜色普遍偏淡，从以白色和米黄色为主的Lully-Vauban小学校舍和基地西侧的公寓楼，到入口边赭石色的住宅楼，均为传统的石造建筑配以镀锌屋顶。相邻的住宅面向街道的立面为红砖砌成，沿入口通道搭设的界墙起始端为浅棕色石材，随坡道上升，逐渐过渡成了赭石及橙色的砖面。项目希望可以融入环境，与周边建筑成为一个整体。为了与环境相协调，新建筑的围护结构采用黄白色调，立面使用砖块，屋顶则覆以釉面瓦，二者颜色相近，使建筑整体呈现出一种均质性。立面上用砖砌筑了三种不同的图案，显得生动活泼。南立面上突出的砖块拼出了醒目的CONSERVATOIRE字样，标明了建筑的功能。底层倾斜的屋顶由奶油色的锌版覆盖，和原有建筑在视觉上形成联系。下水管道也为锌制。

Existing context: The surrounding buildings exhibit a spectrum of pale colors, from the white-beige of the Lully-Vauban school buildings and the apartment building to the west of the site, to the ochre of the residential building located by the porte-cochère entrance. These buildings are all made of traditional masonry with zinc roofs. The neighboring residential building has a red brick street facade. The boundary wall alongside the entrance passageway begins in light brown stone, and then becomes ochre and orange bricks. New-build extension: The project’s intention is to fit in, to integrate itself into this existing environment. Settling into this context, the new building’s envelope is in pale terracotta (white- beige), with a brick facade and glazed tiles on the roof. The roof and facade color are similar (pale) to give the building an overall homogeneity. A play of brickwork using three different patterns enlivens the facades. The word ‘CONSERVATOIRE’ has been picked out on the southern facade in projecting bricks. Only the low sloping roof panels have been covered in a cream-colored zinc. They visually link to the existing building. The gutters are also in zinc.

建筑沿街的墙面和屋顶上的窗框均为漆面橡木，操场侧及沿街侧的凹窗则以石灰橡木做边框。建筑中大部分的窗户都是固定的，除了室内公共空间中与墙面平齐的40厘米深飘窗有明显的窗框，其他窗户的窗框都被藏到了墙内。舞蹈教室内面向街道的开窗为半透明的，与倾斜的白色完成面一同向使用者展现了天空的景观。舞蹈和音乐教室的窗框中安装有浅色的打孔遮阳板。餐厅和原有校舍结合形成的转角处入口上方覆有一片小小的三角形雨棚，由钢结构构成，阳光可以透过其半透明的玻璃顶板照亮餐厅室内。

Exterior window frames on both the facade and the roof are in varnished oak on the street side and limed oak where the openings are recessed on the street and playground sides of the building. Because most of the windows are fixed the frames are not visible, except those that are flush with the facade that give onto shared interior spaces, thus leaving room to install 40cm deep seats in the thickness of the facade. The glazing in the dance studio window that overlooks the passageway is translucent with a white gradient finish giving views of the sky. Pale coloured micro-perforated sunscreening blinds are set into the frames in the dance and music studios. A small triangular awning shelters the canteen entrance in the corner between the new extension and the Lully school building. It has a steel structure with translucent glazing to allow light into the canteen.

室内环境和功能
Interior environment and programme

建筑中设有不同的入口分别通向舞蹈中心、音乐教室和Lully小学，人们也可以通过台阶或街道进入一个公共前厅，再由此去往不同空间。一层的疏散出口直接与Vauban小学的操场相连。舞蹈中心有两层楼高，人们可以从操场直接进入一层空间，或者通过Lully主校舍进入二层；Lully校舍和音乐教室有一个共享的前厅，与校外的街道相连，入口处进行了无障碍设计，方便所有人使用。

走过入口的接待台，人们将进入由橡木和深色陶土构成的流线空间，走廊被扩宽，可以同时作为公共空间使用，在柔和的灯光的照射下呈现出肃静的氛围。天花上设有艺术家Marie Maillard的作品，云一般的图案让人不禁联想到自然、阳光、变化的舞蹈动作和轻细的乐声。褐色的木纹让空间显得温暖而柔和，学生们可以在这里等待他们的课程开始。透过“舷窗”，人们将会看到学生们练习的景象。建筑西侧面向室外通道开有巨大的窗户，阳光可以由此照亮室内空间，而建筑与城市之间的联系也借此被建立了起来。

There are separate entrances for the dance centre, music rooms and the Lully primary school. A shared lobby accessed via steps or lift from the passageway gives access to each of these areas. A fire exit at lower ground floor level leads directly into the Vauban primary school playground. The dance centre is spread over two floors. The upper level is accessed via the main entrance to the Lully school and the lower level directly from the Vauban school playground;  Access via the shared lobby to the Lully school and the music rooms, is direct from the exterior passageway. The lobby has lift access from the passageway for people with reduced mobility.

From the entrance and the reception desk, circulation spaces finished in timber (oiled 3-ply oak) and dark clay render are treated as shared spaces: areas in the corridors have been widened to create convivial spaces.On the ceiling a piece by artist Marie Maillard evokes nature, the sun, the movements of dance and the hum of music. The textures are warm and soft (ochre colours and pale timber). Students can wait for their classes in a dedicated space. Into these spaces comes the faint sound of music, and views of students practicing through ‘porthole’ windows. To the west, a large window giving onto the exterior passage brings light into the two levels of the building and opens the building onto the town.

▼接待空间，楼梯连接上下层，reception space with stairs connecting up and down floors

接待空间被设置在舞蹈中心的入口处，其中设有接待台，有利于同时监察大厅和舞蹈中心的人流。人们可以在大厅中停留、等待，或通过楼梯进入下层空间。更衣室、厕所和储藏间位于舞蹈中心上层的入口附近，两间舞蹈教室位于走廊一端。舞蹈教室的空间高挑明亮，散射光均匀地分布在室内，隔音设计让声音不会对外界造成影响。阳光通过屋顶天窗射入室内，东侧的落地窗让人们可以尽情欣赏操场上的树木；南侧的镜面上方设有水平天窗，让学生可以更清楚地在镜中看到自己的动作。这些舞蹈教室的平面接近方形，变化的层高形成烟囱效应，加强了室内的自然通风，并且有助于提高音响效果。

The reception is situated at the entrance to the dance centre. Its location allows for surveillance of the entrance lobby and the entrance to the dance centre. A reception desk has been provided; The lobby provides a reception area and space for waiting; The stair that leads to the lower ground floor is both visible and accessible from the entrance lobby;  Changing rooms, toilets and storage are located close to the dance centre entrance on the upper ground floor. The two dance studios are at the end of the corridor and they are very light and bright. Sound is confined and light is diffused. Light enters via the roof light (screened from the sun), via the large windows to the east that give full views onto the trees in the playground, and through a horizontal clerestory window to the south situated above the mirror, illuminating the dancers and allowing them to see their reflections clearly. These dance spaces have a rectangular, almost square floor plan, but an asymmetric volume for better acoustics and to enable natural ventilation (stack effect).

▼舞蹈教室，大开窗和天窗为室内带来充足采光，dance studio with large windows and skylight bringing in sufficient natural light

一层的音乐教室气氛较为平和，东边和南边的巨大开窗为室内提供了充足的自然光照，并将操场的景色带入教室之中。在每间舞蹈和音乐教室中都设有单向遮阳百叶，阻挡外界看向室内的视线的同时，允许人们欣赏室外景观。餐厅和音乐教室同在一层，为原有餐厅的扩建，人们可以直接通过巨大的玻璃门从操场进入其中。

The music rooms on the ground floor have been given a fairly neutral ambiance. Large windows to the east and south bring in natural daylight, framed by the trees. In every dance or music space, sunscreen blinds allow views to the exterior while screening the interior. The extension to the canteen is on the lower ground floor and is linked to the existing canteen. Large glazed openings give direct access to the playground.

环境措施
Environmental information

项目团队从整体上对可持续发展进行了考量，每个人都要在自己负责的部分中体现出可持续发展的特点。因此，在每份项目相关的文件，从图纸到文本，都涉及到了为满足可持续发展所面临的环境挑战。可持续发展在这个项目中意味着建筑和环境以及社会现状的基本联系。

项目并没有一味崇尚高科技的节能手段，而是从一些基本的生态和被动设计原则出发，进行了以下几点设计来提高建筑的可持续性：
-钢筋混凝土结构配以保温隔热层，优异的保温性能让室内一年四季都能享受舒适的温度。
-每个房间有两到三个通风口，形成空气对流，带来良好的通风；舞蹈教室中开启的天窗进一步加强了通风效果。
-窗外设置垂直遮阳百叶
-建筑形体紧凑
-室内空间拥有充足的自然采光

The project team has an integrated approach to sustainable development. This means that rather than one member of the team holding this responsibility, everyone does, from architects to consultants. Therefore the environmental challenges behind sustainable development are transcribed in every document relating to the project, from plans to written documents. As such for this project, ‘sustainable development’ fundamentally means a close link between the environment, the building and its social objectives.

Before considering high-performance technical solutions, the basic premise of the design respects a certain number of bioclimatic and passive principals, including:
-A structure (post, beam and slab in reinforced concrete), with external thermal insulation, guaranteeing excellent thermal inertia for year-round thermal comfort.
-Cross-ventilation thanks in particular to a quasi-systematic double aspect (triple in some rooms) that makes the most of prevailing winds. This ventilation is reinforced by opening skylights in the dance studios.
-Exterior vertical sunscreen blinds on windows
-A compact building
-Good natural daylighting in interior spaces.
