它是一座小型城市建筑，绝缘良好(A级)和“低科技”，街道销售面积110平方米，五层写字楼，每层约125平方米。一个非典型的混凝土结构，由办公室AuCarré的Marc Ewen设计，包括可变厚度的楼板，提供11×12米的开放空间。

It is a small urban building, well-insulated (class A) and "low-tech", with a sales area of 110m2 on the street level and five office levels at around 125m2 each. An atypical concrete structure, designed with Marc Ewen from the office Au Carré, including variable thickness slabs, offers an open space of 11×12m.

窗台是倒梁，允许窗户接触天花板，以最大限度地进入自然光。大部分墙是预制混凝土墙，暴露在外.现场浇筑的混凝土板和面纱也仍然很明显，它们有缺陷和不规则之处。坚固的橡木地板带来温暖和高贵的完成，呈现出与结构工作的对比。

The windowsills are inverted beams, allowing windows to touch the ceiling to maximize the entry of natural light. The majority of the walls are pre-made concrete walls, left exposed. The onsite casted concrete slabs and veils are also remaining apparent, with their flaws and irregularities. Solid oak floors bring warmth and a noble finish that presents the contrast to the structural work.

楼梯设计得尽可能紧凑，相当特别：抛光的粗钢，一张高超过15米的大型中央板，悬挂在楼板上；台阶是折叠的金属板，通过间隔器连接到混凝土墙和中央板上，使光线沿着墙壁移动。

The staircase, designed to be as compact as possible, is rather special: polished crude steel, a large central sheet of more than 15m high which is suspended from the roof slab; steps are folded metal sheets that are attached to the concrete walls and to the central sheet via spacers that allow the light drag along the walls.

低科技和aaa，这是非常好的绝缘和配备三重玻璃，优化慷慨的自然照明和框架美丽的景色，令人印象深刻的风景附近的城市火车站和罗通德斯，森林和田野潜伏在城市南部的背景。

Low-tech and AAA, this building is very well insulated and equipped with triple glazing, optimizing generous natural lighting and framing the beautiful views of the impressive scenery of the nearby urban train station and Rotondes, with forests and fields lurking in the background of the south of the city.

自动外遮阳装置在夏季限制外部热负荷，通过自动窗口自然通风，在凉爽的夏夜重新激活混凝土板的热惯量。无需安装空调系统。

Automatic external shading devices limit the external heat load in summer and natural ventilation through automated windows reactivates the thermal inertia of the concrete slabs during cool summer nights. No air conditioning system had to be installed.

工作空间的机械通风由各层的VMC单独进行，具有较高的热回收效率。他们避免沉重的通风单元和整个建筑物的分配管道。如果适用的话，取暖得益于与城市供暖的连接，因此仅限于简单的分配泵和热量计。

The mechanic ventilation of workspaces is done by individual VMC on each floor, which have a particularly high heat recovery efficiency. They avoid heavy ventilation units and distribution ducts throughout the building. The heating, if applicable, benefits from the connection to the urban heating and is therefore limited to simple distribution pumps and calorimeters.

立面是由烧焦的区域落叶松覆层制成的。它的表面用喷灯烧成了日本的传统方式。黑焦层非常坚硬，形成了木材的自然保护。

The facade is made of charred regional larch cladding. Its surface is burned with a blowtorch in the yakisugi* japanese traditional way. The black charred layer is very hard and forms the natural protection of the wood.
