Submerged, solid, rigid, hard, but natural. The organic nature of this structure feeds the relationship between site, building, and human. Submerged in the ground, the visitor centre is brought to life by the porous nature of the lava rocks found in Iceland. Using interconnected void space to channel light, an idea to create a structure from this form emerged. A solid form in a harsh environment, the structure needed treatment to become lightweight. Rather than placing on top of the site, the idea was to connect it with the site in a way that would keep or add value to the site's natural features. To accomplish a smaller footprint on the site there had to be a level of integration interior and exterior spaces in which the public areas of the visitor centre became indoor-outdoor spaces separated by large glazed channels leading from the interior to the exterior. These channels distribute light into the underground areas whilst protecting the scenic value of the landscape above. In accordance with the channels, the light was also distributed through a 2m wide glazed perimeter that captured panoramic views of the sky; the interior private areas utilise frosted skylights. The public area is an integrated space in which the cafe and exhibition share the same floor. This creates a warmer environment in contrast to that of the outside. The children's play area is located inside the largest channel, the space provides a safe outdoor environment that feels enclosed by the warmth of the surrounding visitor centre. The entire building is accessible, with two entrance methods including a spiral staircase and elevator. The circulation method, both internal and external are catered to preference, there is a free of circulation that consumes the external floor, this is influenced by the channels. However, the position of the car park creates an overall direction to take. The materials were chosen by their performance in Iceland's climate, concrete has a high thermal mass, meaning it can retain a lot of heat and cold. By insulating underground, the concrete will retain the warmth of the sun and exert it within each room.
