该项目旨在为Vals石材制造商Truffer Stone A.G.创建一个新的总部和展厅。Vals石材因其独特的表现、高性能和作为建筑材料的适用性而受到建筑师的高度赞赏和追捧。这种石材具有银色金属光泽和从绿色到蓝色的精美色彩，随着光线和水的变化而变化。该项目旨在展示Vals石材的潜力及其卓越品质，结合独特的制造技术、创新细节和应用。
Vals是一个位于山间狭窄山谷中的传统阿尔卑斯村庄。裸露的Vals石材在陡峭的山谷地形上，以及应用于传统房屋屋顶的粗糙石板，定义了村庄的景观纹理。用Vals石材建造的建筑旨在与周围自然环境和村庄的建筑语言相呼应。
建筑体量的设计考虑了场地限制，并遵循当地建筑规范的坡屋顶形状。然后，我们提炼了周围传统阿尔卑斯房屋的可识别建筑特征——屋檐，作为设计的主题。
复杂的三角空间由中央线性空隙构成和组织，楼梯斜向和垂直贯穿整个建筑体量的长度和高度，连接所有功能区。我们的意图是重现采石场的感觉，仿佛置身于岩石的裂缝中。楼梯的比例夸张，狭窄而高，由两面原石面和钻孔的墙壁定义。通过天窗的光线设计了最小的支撑结构，以突出石材的纹理和置身裂缝中的感觉。这个空间象征着采石场，是家族工作、发明和创造的核心和基础。
规划围绕中央楼梯展开。建筑包括一层地下和四层地上。地下室是“石材世界”，设计为展厅、会议和聚会空间，配有展示浴室和一个被天窗柔和照亮的下沉花园。第一层和地面层包含办公室功能，而第二层和第三层则用作私人住宅。
外部包围设计源自传统屋檐，采用粗糙的石板，并以屏风的形式向下延伸。在传统的阿尔卑斯房屋中，窗户较小，因此空间会显得温馨和更具保护感。在本项目中，我们的设计意图是创造开放感和更强的透明感，以便将壮丽的山景作为室内背景的一部分。
屏风由石板和落叶松木板构成，支撑在不锈钢拉索上。它们固定在凹入的不锈钢夹具上，夹具的角度经过精确加工，以匹配屏风的倾斜度。
通过最小化金属配件和支撑结构的尺寸和可见性，屏风给人一种石板轻轻漂浮在窗前的效果。复杂的细节和精确度是通过一系列尝试、测试和挑战制造方法、技术以及向Truffer家族学习石材工艺的过程中实现的。
在地方术语中，Haus Balma意为岩石与倾斜土地之间的空隙，是动物和人类在山中可以得到舒适和安全庇护的地方。我们希望该项目能够与土地有机结合，成为家族和社区的舒适和栖息之所。
The project is to create a new headquarter and showroom for the Vals Stone manufacturer Truffer Stone A.G.Vals stone is known for one of the most appreciated and desired stones by architects for its distinctive expression, high performance, and applicability as the building material. The stone has a silver metallic glitter and exquisite color in the range of green to blue that changes under the light and water. The project aspires to showcase the potential and its exceptional quality of Vals stone with unique manufacturing techniques, innovative details, and applications.
Vals is a village with traditional Alpine houses in the narrow valley among mountains. The Vals stone in bare rock state on the steep valley terrain and rough split of solid stone slate applied on the roof of traditional houses defines the texture in scenery of the village. The architecture with and made of Vals stone is designed to echo the surrounding nature and the architectural language of the village.
The architectural volume was generated to fit to the site constraint and with the pitched roof shape per local building guideline. Then, we elaborated the recognizable architectural feature of surrounding traditional Alpine houses, the eave as the design motif.
The intricate triangular spaces are structured and organized by the central linear void, the staircase that runs diagonally and vertically through the entire length and the height of the architectural volume that connects all programs. Our intention was to recreate a sensation of the quarry, being inside a crack of a rock. The staircase is in exaggerated narrow and tall proportion defined by 2 walls with raw split stoneface and boreholes. The light though the skylight is designed with minimum supporting structure to accentuate the stone texture and sensation of being in the crack. The space is symbolic of the quarry being the core and the foundation of the family work, their invention and creation.
The planning was developed around the central staircase. It is comprised of one level underground and 4 storey above ground. Basement houses the “stone world” which is designed as a showroom, meeting and gathering space with its showcase‐bathroom, and a sunken garden gently washed by the skylight placed over them. While first floor and Ground floor and are comprise of office functions second and third floors are used as private residence.
The exterior envelop design was developed from the traditional eaves with rough split stone slabs and drawing them down in screen manner. In traditional Alpine house windows are small, thus spaces would feel cozy and more protected. In this project our design intention is to create openness with more sense of transparency so to take in incredible view of the mountain as a part of interior backdrop.
The screen is designed with stone slabs and larch planks supported by stainless tension cables. They are fixed on recessed stainless‐steel clamps that are milled at the precise angles to match the inclination of screen.
By minimizing the dimensions and visibility of metal fittings and supporting structure the screen gives an effect as if slates of stone stay afloat gently and subtly in front of the window. The intricate details and precision were possible through a series of trying, testing and challenging manufacturing methods, technic and learning from the mastery of stone, The Truffer family.
Haus Balma in regional term, means a void, a space between a piece of rock and the sloping land where animals and human can be sheltered for comfort and safety in a mountain. It is our hope that the project would grow to be organic to its land, and to become a place for comfort and nesting for the family and the community.
