The architecture of the Midnightsky Chalets can be best described as purist, nature-based simplicity. The structure's shape was derived from a wooden log fallen from the sky, resulting in the triangular shape, the tower-like concept, and the layer-based interial design. The combination of 2D and 3D elements always shows us possible technical solutions in the building process. Prefabrication and modular division were crucial for the success. Besides the unique form of the chalet, it is the holistic approach and the focus on the impact model of the construction, that stands out.
