在奥克西塔尼大区的资助下，La Cité项目旨在对Les Halles Latétoère历史遗迹进行改造，以创建支持合作和可持续创新的第三场所。La Cité承载了数个针对年轻创业者的公共和私人服务，例如Ad’Occ、At Home、Nubbō和Roselab等。

Sponsored by La Region Occitanie, the project of La Cité consists in the renovation of the historic site of Les Halles Latétoère, in order to create a third-place dedicated to collaborative and sustainable innovation. La Cité hosts several public and private services devoted to young start-ups, such as Ad’Occ, At Home, Nubbō and Roselab.

该项目位于图卢兹东南部的Montaudran郊区，紧邻一条沿着Aéropostale历史保护延伸的铁路，建筑本身已被列为图卢兹航空工业历史遗产。该项目的干预范围涉及Latécoère工厂的三个历史大厅，以及几个仓库和雨棚结构和场地东侧的一处废弃区域。本次设计主要集中在建筑内部，包括三个历史悠久的大厅，它们各自的长度为120米，宽度为26米。每个中央空间的土层面积为3082平方米，即总面积为9246平方米。

The project is located in the South-East of Toulouse, in the suburb of Montaudran, next to the railway running along the protected historic runway of the Aéropostale. The building itself is registered as heritage of the aeronautical industrial history of Toulouse. The perimeter of our intervention included the three historic halls of the Latécoère factory, along with several warehouses and canopies, plus a disused area at the Eastern side. The project of La Cité is concentrated mostly inside of Les Halles Latécoère and is composed of the three historic halls which are 120 meters long and 26 meters wide. Each nave has a soil floor surface of 3082 m², meaning a total of 9246 m² for the three naves.

屋顶翻新

Roof Renovation

项目要求完全拆除并更新屋顶瓦片，以便替换板条，清除被损坏的构件，并增加一道轻薄的隔热层。位于屋脊的天窗被保留下来，继续为空间引入天顶的日光。屋顶远端的两个开口被扩大并覆盖以手工瓦，从而与立面的玻璃墙保持对齐。以上动作均是基于1917年至1955年便已在西南立面使用的布局而完成的。在与地区历史古迹部门主管进行讨论后，设计团队决定保留目前的屋顶体量，并且专门为之开发了一个木结构原型，以填补框架单元之间的不规则空间。此外，出于技术和审美方面的考虑，板条与瓦片之间还增加了一道5cm的隔音层，并与下层板条保持了5cm的间距。从屋顶的底面可以看见板条之间的交替，就和过去一样。

The project required the complete removal and renewal of the roof-tiles in order to renovate the batten, add a thin layer of insulation and replace the damaged tiles. We kept the skylights on the roof ridge for their zenithal day-light they bring into the space and we enlarged and covered with mechanic tiles two openings on the far ends of the roof, in order to align them with the glass walls of the façade. This refers to a disposition already used on the South West façade from 1917 to 1944. After discussions with the regional curator of Historic Monuments we decided to preserve the current volumes of the roofs which made us develop our own wooden prototype shaped to fill irregular spaces between elements of the framework. In addition, a 5 cm acoustic insulation layer was added between the batten and the tiles with a 5 cm spacing with the lower batten for both technical and aesthetic reasons. The alternation between the battens is visible on the underside of the roof, as it had been in the past.

立面设计

Façades Concept

新的横向立面被设计为轻型立面，采用了垂直且扭转的金属叶片，能够根据不同视角重现曾经的拱门印象。西南立面沿着铁轨延伸，这里的金属叶片呈水平方向安装，可作为遮阳板使用，总体上仍与其他立面保持了相同的模式。原先遮挡着前卸货码头的混凝土支柱被拆除以突显结构。

The new transversal façades are designed as light façades with the use of vertical twisted metal blades which reproduce the impression of the former arches, depending on the perspective. The South West façade, running along the rail-track, displays the same pattern, although the blades are horizontally oriented to work as sun shades. The concrete awning pillars sheltering the former loading dock are stripped bare to magnify the structure.

侧立面采用了窗户和支柱交替的设计，并借助垂直叶片来标记出每个入口。这使得西南朝向的办公室可以直接利用自然采光，同时不干扰外墙在视觉上的韵律感。在主入口的上方，叶片呈水平方向放置，以创造一个具有仪式感的顶棚。

Concerning the lateral façade design, it alternates openings and pillars and reiterates the use of vertical blades to mark every entry. This allows a direct and natural lighting of the South West offices while conserving the alternating rhythm on the façade. Above the main entrance, the blades are horizontally oriented to generate a monumental access awning.

室内布局

Interior layout

该项目以既有建筑的网格为基础，开发了一个由木梁和立柱构成的5x5m的特制网格。该网格由全玻璃面板、半玻璃面板和全木质面板填充。所有的隔热和隔音材料均被整合至这些面板当中，构成了一个全面且灵活的模块化系统。这个占据了两层楼的轻型系统旨在适应该项目最基本的办公用途。楼层平面横跨了三个网格宽度，并在此基础上发展处15米的平台宽度，形成可以容纳约40个办公桌的开放空间。

The project develops a design grid of wooden beams and pillars based on the grid of the existing building. This grid of 5m by 5m is filled by either fully glazed panels, panels including a glazed section above a wooden apron wall, or fully wooden panels. All thermal and acoustic insulation is fully integrated into these panels composing a completely flexible and modular system. This light construction system on two floor levels is designed to accommodate the most common use in the program, office space. The floorplan spans 3 grid widths developing plateau width of 15m allowing to create open-spaces of about 40 desk stations.

休闲空间位于两个体量之间，围绕着技术区域组织，后者整合了厨房区、洗手间、复印区和各类技术装置。休闲空间所处的位置使办公区域得以基本保持开放和平静，无需增加额外的空间或设备。在上方楼层，一座天桥将所有的模块连接至开阔的中央空间周围。

The recreational areas are located in between two plateaus and are organised around technical blocs integrating the kitchen blocs, toilets, copy areas and technical installations, keeping the office plateaus largely open and calm, freed of any annexe surfaces and equipment. On the upper level, a footbridge connects all the modules around the large central space.

室内修复

Interior restoration

空间中原有的砖砌立柱被剥除了多余饰面，以展示并放大它们的色彩变化，同时也让砖石能够自然地呼吸。凹槽式的接缝使它们在视觉上与地板相互区别，并避免了毛细血管作用导致的渗水。混凝土立柱得到了修复，工业化的弧形梁也被保留下来。

The brick pillars were stripped down to reveal and magnify their variations in colour bur also to allow the masonry to breathe naturally. A recessed joint also detaches them visually from the floor and avoids water infiltration by capillarity. The concrete pillars are repaired and the industrial rolling beams are preserved. The rolling beam in the central nave is locked in place and the rolling beam of the third nave is moved and repositioned in the central nave as well.

The ecosystem square: This space is a public square, partly mineral and partly planted to create a cool green environment, a place of free expression and interaction equipped with benches. This space is at the heart of the system, welcoming, uniting and connecting users.

The heart of the ecosystem: At the center are located the services, meeting rooms, restauration and connection to other areas. This is the first space the visitor encounters and as such represents the system. It’s a place of encounters with the conference room as the crown jewel. Modular in terms of use, its comfort and flexibility contribute the quality of the whole project.
