位于沙特尔-德-布列塔尼，在住宅区和协会大楼之间，ASSIA（个人援助协会）的总部希望扩展到现有部分南部的一个600平方米的地块上。
Located in Chartres-de-Bretagne, between a residential area and association buildings, the headquarters of ASSIA (an association for personal assistance) is looking to extend onto a 600 square meters plot to the south of the existing part.
新的是三层楼高，提供了一个大的楼层面积，同时保留了最大限度的自由土地。独立的扩建部分仅由一条玻璃走道连接，允许在两部分之间创造一个种植空间。
The new one is three stories high, providing a large floor area while preserving a maximum amount of free land. The detached extension is connected only by a glass walkway allowing the creation of a planted space between the two parts.
我们的思考使我们回应了一个可以随着时间发展的具体方案。我们在地块的南侧创造了一个独立的托盘，在一个由木柱和木梁组成的建设性框架上，间隔三米。这个框架允许至少有11平方米的办公室，可以组合成几个实体。
Our thinking led us to respond to a specific program that could evolve over time. We have created a free-standing tray on the south side of the plot, on a constructive framework of wooden posts and beams, spaced three meters apart. This framework allows for a minimum of 11m² of offices that can be grouped into several entities.
它们被安置在南部，以利用开放的视野和光线。预先老化的木质遮阳板在夏季保护工作空间免受阳光直射。由预制混凝土制成的硬核（楼梯、电梯和技术室）与自由木地板相邻。一条走廊为不同的办公室服务，作为电力和通风的技术支持（假天花板）。
They are positioned to the south to take advantage of the open views and light. A pre-aged wooden sunshade protects the workspaces from direct sunlight in summer. The hardcore, made of prefabricated concrete (staircases, lifts, and technical rooms) is adjacent to the free wooden floor. A corridor serves the different offices as technical support for electricity and ventilation (false ceiling).
整个项目都是预制的；包括中央混凝土核心和木质柱梁系统以及CLT地板。所有的材料都被暴露出来，以确认施工方法和不同的材料处理。遮阳板和覆盖层是由预老化的木材制成的，有五厘米宽的叶片，显示了外墙处理的薄度。
The entire project is prefabricated; both the central concrete core and the wooden post and beam system and CLT floors. All the materials are left exposed to affirm the construction methods and the different material treatments. The sunshades and the cladding are made of pre-aged wood, with five centimeters wide blades, demonstrating thinness in the treatment of the facade.
它们的方面根据太阳的方向而变化，伴随着三层玻璃幕墙，在白天反映了环境，在晚上显示了木地板。
Their aspect is changing according to the orientation of the sun, accompanied by the triple glazed curtain wall which reflects the context during the day and reveals the wooden floors in the evening.
