目的是研究芦苇作为外墙和屋顶覆层材料的适宜性，特别是在高海拔的高山地区。
The objective is to research the appropriateness of reed as facade and roof cladding material, especially in high altitude alpine regions.
芦苇生长迅速，形成一个有价值的生物群落，产生更好的水质，并为多种动物提供一个家。植物的死立部分每年都会被新的植物取代。只有植物的死亡部分将被收获，并可作为外墙和屋顶的覆层材料，而无需进一步处理。在生命结束时，芦苇是可堆肥的，并关闭了材料的生命周期。
Reed grows fast, forms a valuable biotope, generates better water quality, and provides a home for multiple animals. The dead-standing part of the plant is going to be replaced by new plants every year. Only this dead part of the plant is going to be harvested and can be used as a cladding material for the facade and roof without any further treatment. At the end of life, the reed is compostable and closes the material life cycle.
芦苇–也被称为茅草–在任何意义上都是一种可持续的、可再生的、碳中性的资源，似乎是建筑围护结构的一种完美的替代可再生材料：生长迅速，过程链短，能源需求和排放低，完美的生命周期，没有污染物，经过几代人的证明。
Reed – also known as thatch – is in every sense a sustainable, renewable, carbon-neutral resource and seems to be a perfect alternative renewable material for the building envelope: rapid growth, short process chain with low energy demand and emissions, perfect life cycle, no pollutants, proved over generations.
经过斯图加特大学建筑技术与设计学院IBBTE两年的研究和项目开发，我们于2019年8月在奥地利福拉尔贝格州曼海姆山庄（2600米）附近的高寒地区建造了第一个茅草项目。建筑围护结构采用当地的茅草和木材，尽可能减少金属连接和其他材料。
该建筑保证了主屋的供水，需要一个新的外观。我们决定使用现有的石头建筑作为新的木制结构的基础，以尽量减少对这个合理环境的干预。
After two years of research and project development at the Institute of Building Technology and Design IBBTE at the University of Stuttgart, we built in August 2019 the first thatched project in high alpine surrounding close to Mannheimer Hut (2600m) in Vorarlberg, Austria. The building envelope has been realized in local thatch and wood by reducing metal connections as far as possible and all other materials.
The building guarantees the water supply of the main hut and needed a new appearance. We decided to use the existing stone building as the foundation for the new wooden structure to minimize the intervention into this sensible environment.
设计需要简单，并适合于地点和用途。主要的重点应该放在材料本身及其建筑和手工-技术协调的细节上。在规划的早期阶段，将经验丰富的茅草工匠纳入其中，对于开发相关材料的简单和适当的细节至关重要。一个由工匠、学生和教职员工组成的团队共同开发和建造了平衡。
The design needed to be simple and appropriate to location and use. The main focus should be on the material itself with its architectural and manual – technical coordinated details. The integration of experiences thatch craftsmen in an early stage of planning was essential to develop simple and appropriate details for the material involved. A team of craftsmen, students, and faculty staff developed and built balanced together.
但是，我们是如何得到这种材料的呢？这在开始时是一个非常正式的方法。我们意识到，在他们的山地小屋的设计工作中，学生们试图用一种材料来设计整个围护结构–外墙，和屋顶，以产生一个整体的设计。
But how did we get to this material? This was a very formal approach in the beginning. We realized that in their design work for a mountain hut the students attempted to design the full envelope – façade, and roof – out of a single material to generate a monolithic design.
因此，我们研究了以下可用于这种方式的学生工作室材料。除了石头、混凝土、木材和金属，我们重新发现了茅草这种材料，它几乎可以实现类似于混凝土的非常立体的设计。这立刻吸引了我们，并导致了进一步的研究和建造一个茅草围墙原型的想法。
So we researched the following student workshop materials which could be used in this way. Besides stone, concrete, wood, and metal we rediscovered the material thatch which allows a very three-dimensional design analog to concrete almost. This fascinated us right away and led to further research and the idea of building a prototype thatched envelope.
