An active quarry is a constantly changing landscape. Its raw and edgy character express an ongoing conflict between nature on the one hand, and human influence on the other. This inspired the design of a building carved out of the rock by the diamond wire saw, a technique used in the quarrying process. The approach of the project was to make a factory producing building- and paving-stones from waste material provided by the quarry, and to show the characteristics and potential of the available stone in the architecture. The larvikite rock dates back 300 million years. The crossover of architecture and nature in this building therefore pushes the concept of time to the forefront. It raises the question of what the site used to be, what it is now and what it might become in the future.
