在一个16000平方米的建筑中，该建筑结合了一个向城市开放的混合项目。在办公楼和酒店内，用户可以使用协作空间和各种各样的食物选择，而向公众开放的食物场所则参与底层街道和社区的动画。

在拉德芳斯大道和铁路之间，建筑的结构和立面在振动和声学性能方面具有高水平的性能。

Between the boulevard de La De?fense and the railway, the structure and the fac?ades of the buildings are designed with a high level of performance in terms of vibrations and acoustic performance.

该项目的两个项目元素，一个酒店和一个办公楼是分开的，但沿东西轴线相邻。在HOTEL OKKO，用半反射铝板覆盖，仍然是一个完整的整体，InDe?fense办公楼被分割成更小的整体，每一个都被推入或挤压，以将狭长的场地开放给周围环境，并为建筑增加深度。

The project’s two programmatic elements, a hotel, and an office building are separated but adjoined along their east-west axis. Where Ho?tel OKKO, clad in semi-reflective aluminum panels, remains an unbroken mass, the InDe?fense office building is split and shifted into smaller masses, each pushed in or extruded to open the long and narrow site to its surroundings and add depth to the fac?ade.

InDe?fense建筑的立面是一个动态的推拉游戏，挤压/后退的体积形成了阴影的悬挑或宽敞的采光露台。这些种植的户外空间除了提供空间多样性外，还融合了环境和感知的亲生物属性——这些属性被证明对工作场所生产力和健康有积极影响。分布在不同楼层的露台、内部楼梯间及其走廊以及两个外部楼梯使InDe?fense成为一座充满活力的建筑，向城市开放，让每个人都能看到用户创造的激情。

The fac?ade of the InDe?fense building is a dynamic play of push and pull, the extruded/ receding volumes creating shaded overhangs or generous daylit terraces. These planted outdoor spaces, in addition to providing spatial variety, incorporate both contextual and perceptual biophilic attributes – attributes proven to have positive effects on workplace productivity and wellness. The terraces distributed over different levels, the interior stairwell and its galleries as well as the two exterior staircases make InDe?fense a lively building, opening up to the city, which allows everyone to see the effervescence created by its users.

一个有遮蔽的露天停车场，在地面上用作自行车停车场，连接着两座建筑，中间有一个螺旋楼梯。从街道上可以看到的壁画将被安装在该空间的侧墙上，旨在激发好奇心，为城市带来艺术。

A sheltered agora, used as a bike parking at the ground level, links the two buildings and is punctuated by a spiral stair. A mural, visible from the street, will be installed on the side wall of that space aiming to encourage curiosity and bring art to the city.

豪特尔OKKO。HOTEL OKKO位于场地的西部，共有9层184间客房。在一楼，一家餐厅可供酒店客户、社区和周围办公室的员工使用，营造出活跃而繁忙的街景。一楼设有共享设施，其中包括一个300平方米的休息室和一个专供酒店游客使用的专用露台，他们可以在入住期间随时使用。酒店内部由Studio Catoir设计。

Ho?tel OKKO. Located on the western portion of the site, Ho?tel OKKO houses 184 rooms over nine floors. On the ground floor, a restaurant is accessible to hotel customers, the neighborhood, and to employees from the surrounding offices to create an active and busy streetscape. The first floor is occupied with shared amenities, among other things a 300 sq m lounge and a dedicated terrace for hotel visitors that they can use anytime during their stay. The interior of the hotel was designed by Studio Catoir.

独特的立面。总之，立面的倾斜和有色铝盒使其具有近乎透镜状的质量，根据观众的视角、一天中的时间甚至季节，呈现玻璃般透明或彩色金属。在这一背景下，HOTEL OKKO的反射式立面突出了背景，并赋予了该项目自己的身份，而InDe?fense建筑的独特的青铜色立面则为社区带来了温暖和氛围。

Distinctive Fac?ades. Together, the fac?ade’s angled and tinted aluminum cassettes give it a nearly lenticular quality, appearing glassily transparent or colorfully metallic depending on the viewer’s perspective, the time of day, and even the season. Within the context, the reflective fac?ade of the Ho?tel OKKO stands out of the context and gives the program its own identity, while the distinctive bronze-tinted fac?ade of the InDe?fense building brings warmth and atmosphere to the neighborhood.

楼梯连接多个楼层。该建筑围绕着一个内部螺旋楼梯，设置在中庭内，毗邻全玻璃北立面。这些楼梯的设计旨在鼓励坐在大楼楼层对面的同事之间进行互动、交流和知识共享。楼梯位于电梯大厅附近的每一层，需要穿过楼层的共享平台，这有助于跨楼层的同事之间的互动。

Stairs connect more than floors. The building is organized around an interior spiral staircase set within an atrium adjacent to the full-glazed north fac?ade. Those stairs are designed to encourage interaction, communication, and knowledge sharing among colleagues sitting across the building’s floors. The staircase, which alights on each level adjacent to the elevator lobby, requires passing through the floor’s shared landing – facilitating opportunities for interaction between colleagues separated across the floors.

社交空间散布在整个建筑中，在中庭内的室内露台和室外露台中，这些露台覆盖了建筑突出的外部空间。选择的室外露台由另一个室外螺旋楼梯垂直连接，游客可以爬上屋顶，欣赏拉德芳斯和巴黎的全景。

Social spaces are scattered throughout the building, in indoor terraces within the atrium and outdoor terraces that crown the building’s extruded exterior volumes. Select exterior terraces are connected vertically by another outdoor spiral staircase that allows visitors to climb up to the rooftop and enjoy panoramic views over La De?fense and out to Paris.

办公楼的正面设计有通风切口开口，集成在不透明暗盒内（通过穿孔侧板），以提供由实心面板和无可见框架的大型玻璃面板制成的“干净”设计。立面的棋盘式结构有助于热调节，并在工作空间中创建光影效果，“加利福尼亚”百叶窗增强了这种效果，允许用户调整掩星，并使人联想到立面的建筑风格。

The fac?ades of the office building are designed with openings for ventilation cuts integrated within the opaque cassettes (through a perforated side panel) to offer a “clean” design made of solid panels and large glass panels with no visible frames. The checkerboard composition of the fac?ade contributes to thermal regulation and creates a light and shadow effect in the workspaces, enhanced by the ? Californian ? blinds, which allow users to adjust the occultation and are reminiscent of the facades’ architectural style.
