The Iceland Thermal Springs Guest House is located in a picturesque area that showcases the essence of Nordic architecture, harmonizing with the natural surroundings. This facility is designed to serve as a peaceful retreat, providing guests with a comfortable space that emphasizes sustainability and a connection to the outdoors. The overall design concept focuses on arranging cabin modules in both horizontal and vertical grids, which allows for efficient construction and potential future expansions.

Architectural Configuration

The building is oriented along the NE-SW axis, optimizing solar gains while using renewable energy sources effectively. Solar panels installed on the roof harness sunlight, and geothermal energy is utilized for heating common and private areas, reinforcing the commitment to sustainability. The design creates a distinct separation between communal spaces and private accommodations, enhancing the guest experience.

Spatial Organization

On the ground floor, the layout includes a reception area, luggage lockers, a spacious living room, and a shared kitchen. These spaces encourage community interaction among guests while still providing privacy. Large glass façades on the NW-SE axis allow for ample natural light and breathtaking views of the landscape, reinforcing the bond between indoor spaces and the environment outside.

Guest Accommodations

The second floor features nine uniquely designed bedrooms, each equipped with a living area that includes a fireplace, dining space, and private bathroom. Private outdoor hot tubs provide guests with an opportunity to engage with the natural surroundings. The extensive use of glass throughout these accommodations maintains the theme of connectivity with the outside, inviting guests to experience nature while enjoying their retreat.

Sustainable Systems

An important feature of the guest house is the geothermal heating system that supports energy efficiency. Underground drains collect rainwater, which is complemented by a water reuse tank and both vertical and horizontal underground pipe loops. An internal heat pump circulates this collected water, extracting natural heat from the ground to maintain comfortable temperatures throughout the building, reducing reliance on conventional fuels.

The design of the living spaces includes private balconies that allow guests to immerse themselves in the surrounding scenery, enhancing the overall experience of the retreat.
