正规城市规划--法国布列塔尼首府雷恩启动了多个大型城市发展项目，其中最引人注目的是通过 ZAC（Zone d'aménagement concerté）欧洲雷恩火车站改造整个火车站区域，包括全新建设主火车站。雷恩与 350 公里外的巴黎 TGV 高速铁路网相连，列车每小时一班，全程仅需 100 分钟。因此，火车站区域的价值大幅提升，真正推动了该市的城市发展。

  法国国营铁路公司（SNCF）腾出了铁轨沿线的大片土地，并逐步出售给出价最高的项目开发商。该市成立了一个半公共城市开发公司，将土地分配与竞赛挂钩，建筑师团队的设计在竞赛中起着决定性作用。这是确保城市和建筑质量的一种尝试。由菲利普-加佐（Philippe Gazeau）和路易-帕亚尔（Louis Paillard）组成的 FGP 团队与 Agence Ter 合作，被选为整个区域的总体规划设计师。

  总体规划假定，单个建筑相邻而立，体量松散，类似于城市别墅和较小的高层建筑，因此，尽管城市密度很高，但仍能营造出开放的城市印象。这些建筑形成了经典的街道和广场。此外，总体规划要求所有建筑的立面在平面和剖面上都要倾斜，包括设计成 "岩石 "状悬挑的立面，以营造有机的雕塑效果。受客户 Legendre Immobilier 的邀请，Atelier Kempe Thill 与雷恩建筑事务所 Atelier56S 一起参加了火车月台正对面博蒙特建筑工地的设计竞赛。

  Formal Urban Planning - Rennes, France, the capital of Brittany, has initiated several large urban development projects, the most spectacular of which is the reorganization of the entire train station area with the ZAC (Zone d’aménagement concerté) EuroRennes, including the completely new construction of the main train station. This development is the logical consequence of the connection of Rennes to the TGV high-speed railway network to Paris, 350 kilometers away, with a journey time of just 100 minutes and trains running every hour. The station area has therefore increased significantly in value and given a real boost to the city’s urban development. The French railway company SNCF has freed up a wide swathe of land along the tracks and is gradually selling it to the highest-bidding project developers. The city has founded a semipublic urban development company that links the allocation of land to competitions in which the design of the team of architects plays a decisive role. This is an attempt to ensure urban and architectural quality. The FGP team of Philippe Gazeau and Louis Paillard, in collaboration with Agence Ter, was chosen as the master planner of the entire area. The master plan assumes that individual buildings stand next to each other as loose volumes similar to urban villas and smaller high-rise buildings, thereby creating an open city impression despite high urban density. The buildings form classic streets and squares. In addition, the master plan requires all buildings to have façades that slope in both plan and section, including façades that are designed to overhang in a “rock-like” manner to create an organic and sculptural effect. Atelier Kempe Thill, together with the Rennes-based architectural firm Atelier56S, were invited by the client Legendre Immobilier to the competition for the Beaumont construction site directly opposite the train platforms.

 混合方案-博蒙特项目的方案包括总建筑面积约 31,000 平方米，其中公寓和办公楼各占一半。这些区域将由一栋高层住宅和两栋中层办公楼组成，所有建筑在底层相连。住宅楼包含不同类型住宅的混合组合。在前五层，有 121 个单间，是一种长期酒店式公寓，可供商务旅客等租住数周。这些单元的面积在 16 至 22 平方米之间。上面四层交给了雷恩住房协会，共有 41 套社会公寓，居住面积在 44 至 112 平方米之间。顶层八层共有 46 套公寓，面积在 36 至 155 平方米之间。办公楼的设计面积约为每层 450 至 900 平方米，从而满足办公楼租赁市场的需求。

 在这里，开发商从半层的最小单元开始，采用了非常不同的分割方案。为了充分满足不同的项目要求，所有三栋建筑都采用了功能中立、分隔灵活的平面设计。建筑由承重外墙和承重通道核心筒组成。所有隔墙，包括公寓之间的隔墙，均由轻质材料制成。底层设有几家餐厅、一个健身俱乐部和一个带维修车间的大型自行车库。整个建筑群有一层地下室，用于建造地下停车场。在建筑体量之间，将建造与人行道相连的中间区域，每个区域都将作为扩大的室外公共空间，并将设计成带有植物的露台。

 Hybrid Program - The program for the Beaumont project includes a total of about 31,000 square meters of gross floor area, which is roughly divided by half into apartments and offices. These areas are to be realized with a residential high-rise and two medium-rise office buildings, all of which are connected on the ground floor. The residential tower contains a very hybrid constellation of different types of housing. On the first five floors, there are 121 studios in a kind of long-term hotel for rentals lasting several weeks, for example to business travelers. These units are between 16 and 22 square meters in size. The four floors above were handed over to the Rennes housing association as a total of forty-one social apartments with living spaces between 44 and 112 square meters. The top eight floors contain forty-six apartments between 36 and 155 square meters. The office buildings are designed to create areas of between about 450 and 900 square meters per floor, thus meeting the requirements of the rental office market. Here the developers assume very different division options, starting with the smallest unit of half a floor. To be able to respond adequately to the widely divergent programmatic requirements, all three buildings are designed with functionally neutral and flexibly divided floor plans. The construction consists of load-bearing façades in combination with load-bearing access cores. All partition walls, including those between the apartments, are made of lightweight construction. The ground floor offers space for several restaurants, a fitness club, and a large bicycle storage room with a repair workshop. The entire complex has a one-story basement for an underground car park. Between the building volumes, intermediate zones linked to the footpath will be created, each of which will function as expanded public spaces outdoors and will be designed as terraces with plants.

锥形建筑-建筑师们面临着如何在这个项目中定位自己的问题，尤其是在城市规划要求方面。两家事务所都主张基于逻辑和理性的建筑设计，认为从外部强加的纯粹形式束缚是有问题的。通过研讨会式的竞赛过程和几次临时陈述，我们很快就发现，其他设计方案，例如以多层建筑为基础的横向分层设计--从而使上面的建筑体量之间有更大的距离--是不会被接受的。在与评审团的讨论中，我们产生了这样一个想法，即利用所需的坡度，不仅营造出一种正式的姿态，还能提高项目内的生活质量。倾斜的平面布局极大地改善了楼宇之间的狭窄距离，使楼宇之间的空间向外开放，从而为楼宇之间带来更多的光线，并放松了视觉关系，尤其是在公寓中。

对于所需的垂直坡度也采用了同样的策略：建筑物的外墙略微倾斜，使空间朝向天空，同时也提供了更多的光线。这是通过在外立面上大约 15 厘米深的凹槽来实现的，这就产生了一种略带金字塔形的效果。其结果是形成了一种形态，创造了一种有形的大都市密度，容纳了大量复杂的项目，同时实现了较高的城市通透性、良好的视觉连接以及建筑物之间尽可能多的采光和阳光。

Conical Buildings - The architects were faced with the question of how to position themselves in this project, especially concerning the urban planning requirements. Both offices stand for architecture based on logic and rationality, which finds a purely formal corset imposed from outside problematic. Thanks to a workshop-like competition process with several interim presentations, it quickly became clear that alternative designs which, for example, are layered more horizontally with multistory bases—therefore allowing more distance between the building volumes above—would not be accepted. The discussions with the jury gave rise to the idea of using the required slopes in such a way that they not only create a formal gesture but also increase the quality of life within the project. The narrow distances between the buildings are greatly improved by sloping floor plans, which open the spaces in between to the outside and thereby bring more light between the buildings and relax the visual relationships, especially in the apartments. The same strategy is used for the required vertical slope: the buildings have slightly inclined facades that open the spaces toward the sky and also provide more light. This is achieved through approximately 15-centimeter-deep recesses in the façades, which gives rise to a slightly pyramidal effect. The result is a morphology that creates a physically tangible metropolitan density, accommodates great programmatic complexity, and at the same time enables high urban porosity, good visual connections, and as much light and sun as possible between the buildings

混凝土外骨骼 - 在法国，住宅和办公楼最经济有效的建筑方式仍然是混凝土结构的承重外墙与同样由混凝土制成的结构核心筒相结合。许多法国建筑公司为这种连接天花板和外墙的系统开发了自己的隔热系统，以便以经济有效的方式控制热桥。混凝土的美观度相当低，而且通常会被覆盖。博蒙特项目的客户是 Legendre Immobilier 公司，这是一家专门从事混凝土结构的中型建筑公司的开发部门，该公司还拥有自己的预制件工厂。

建筑设计团队以这些非凡的环境为设计出发点，将法国常见的建筑逻辑转化为精致的外骨骼，外墙完全由混凝土预制构件制成。我们的想法是对外壳进行美学设计，这样就不需要覆层。建筑直接变成了建筑。之所以能够采用这种方法，是因为设计工作采用了 "设计与建造 "的方式，通过各种模拟和 "从文件到工厂的规划 "与建筑公司直接合作，而没有采用公开招标的复杂条件。

Exoskeleton in Concrete - The fundamentally most cost-effective construction for residential and office buildings in France is still a load-bearing façade made of structural concrete in combination with a structural core, also made of concrete. Many French construction companies have developed their own thermal break for this system for connecting ceilings to façades in order to keep thermal bridges under control cost-effectively. The concrete is of rather low aesthetic quality and is usually covered. The client for the Beaumont project is Legendre Immobilier, the development department of a medium-sized construction company specializing in concrete structures, which also owns its own precast factory. The architectural team took these remarkable circumstances as a design starting point and translated the construction logic common in France into a refined version of an exoskeleton with a façade made entirely of precast concrete elements. The idea is to design the shell aesthetically so that no cladding is required. Construction directly becomes architecture. This approach was made possible thanks to the design work as “Design & Build” in direct collaboration with the construction company with various mock-ups and “file-to-factory planning,” without the complicated conditions of a public tender.

The system is designed to be relatively simple in terms of columns and beams. Visually, the beams span from one column to the next, but in reality, the system has been rationalized and the beams largely span over two supports, but then have a visually important false joint above the middle support. Columns and beams are designed with inward bevels, again in continuation of the large, beveled shape of the buildings, here with the aim of allowing more light into the apartments. The beveling of the finished parts also creates a tapering in the external view, which gives the inherently heavy components more lightness and elegance. The corner columns are mitered so that the façade runs evenly all around. In contrast to most other European countries, the risk of thermal stresses with possible dangerous cracks due to this externally placed support structure, as well as the water tightness, especially of the structural nodes, which at first glance seems difficult, are seen as manageable. The setbacks of the façade on each floor are ensured by the receding supports, which, despite the receding, still have plenty of overlap with the support underneath so that enough reinforcing material can be passed through. The concrete is removed and remains untreated apart from a water-repellent impregnation. The quality of the concrete is the decisive element for the final appearance of the building. As a conscious design strategy, the architectural language of deep concrete elements helps to respond to various unforeseeable things, such as occasionally differing window systems, while still maintaining a robust design backbone.
