Four Blox is located at the entrance to Grjótagjá Cave in Iceland. The facility serves as a visitor center, enhancing the experience for those exploring the nearby geological site. The design relies on simple geometric shapes that blend with the natural landscape. The volumes arranged throughout the building guide visitors while highlighting the area's beauty.

Architectural elements include specific volumes that support different activities. The BLOCK serves as a transitional area, directing visitors from the entrance to the visitor center. This approach enriches the visitor's anticipation before they enter the cave.

Vertical movement is facilitated through a VERTICAL VOLUME, utilizing stairs that elevate views of the surrounding landscape. The café is placed in a horizontal volume above, allowing visitors to enjoy panoramic sights while they relax and refresh.

Sustainability features prominently in the design. A ZERO MASS SOLAR ROOF helps generate energy and collects moisture from the air. The structure is reinforced by an ANCHOR system, which maintains stability while allowing innovative spatial arrangements.

The inclusion of gabion walls is a significant detail in the project. These walls provide a practical construction option that requires little upkeep. They integrate well with the local stone environment, adding texture and depth. As light interacts with these walls, it creates interesting patterns and shadows inside the building, enhancing the overall visitor experience.
