Hotel Gjá is located in Iceland on the Mid-Atlantic Ridge, where the earth's tectonic plates create a unique landscape. The design centers around the concept "Feeling the Earth Live," aiming to connect guests to the geological activity occurring below. The hotel serves both as a place for rest and a means to experience the natural world in a profound way.

Design Concept

The concept highlights the relationship between architecture and the surrounding volcanic landscape. Hotel Gjá is designed to enhance guests' awareness of the energy and vibrancy of the earth. The entry features a gap between rock formations, allowing visitors to step into a space that emphasizes a connection to nature. This moment prepares guests for an experience focused on the elements and the land's rhythms.

Spatial Organization

The layout encourages interaction with the landscape. Rooms are strategically placed around flowing water and shared spaces, promoting a sense of community. Each room is oriented to take advantage of natural light and views of the remarkable scenery. Guests find themselves on raised lava formations in the sleeping areas, linking the experience to the geology of the site. This physical connection reinforces their bond with the natural world.

Materiality

The design draws inspiration from traditional Icelandic grasshouses, incorporating local architectural traditions. By using excavated and stacked lava in the construction, the design addresses both structural needs and the story of the land itself. This choice demonstrates a commitment to creating a building that respects and integrates with its environment.

Sustainability and Energy Efficiency

Geothermal energy sourced from the nearby Bjarnarflag Geothermal Power Station supports the hotel's energy plan. This system provides heating to different areas while minimizing environmental impact. The incorporation of natural geothermal heat allows the design to align with sustainable practices, highlighting the relationship between the built environment and the earth.

The play of natural light is a key feature of Hotel Gjá. Large windows invite views of the aurora borealis after nightfall. Guests can witness this stunning phenomenon from inside their rooms, experiencing the magic of the northern lights first-hand. The design captures these natural elements, emphasizing the connection to the environment in a simple yet powerful way.
