Selected materials, individual structural elements and the entire structure are designed for maximum durability. The used material minimizes technical interventions during the lifetime of the building. In the natural conditions of the upper parts of Boubín, the lifetime of the wooden structure is low, requiring periodic corrections and related interventions in a naturally valuable location. Therefore, we decided to use UHPC construction material in the project. Its benefits will be well applied in the most valuable area of the Protected Landscape Area. Thanks to the well-chosen construction material and sensitive design, we can present the most basic ideas of correct construction in the most valuable natural sites. Modern, but with respect for the environment we are in. For our design, ecology and sustainability of the building is hidden above all in the minimization of the volume of transported material, in its long life and in the simplicity of the construction itself.
