Exposed Concrete and Andesite Spa Blending with Icelandic Landscape for Community Relaxation

Project in-detail

Exposed concrete and locally sourced andesite define a serene beer spa that integrates harmoniously with the stunning landscape of Lake Mývatn, offering a unique retreat for wellness and relaxation.
5 key facts about this project
01
Exposed concrete and andesite elements create a seamless connection with the natural landscape.
02
The design incorporates terraces that enhance outdoor experiences and provide optimal views.
03
Sustainable practices are integrated through the use of geothermal energy for heating.
04
Grass growth on select surfaces symbolizes the merging of architecture and nature over time.
05
The layout fosters community interaction by linking multiple wellness facilities in a cohesive design.

### Project Overview

The design is situated along Lake Mývatn in Iceland, with the intent to harmonize the built environment with the natural landscape. Central to the project is a beer spa, strategically designed to enhance the sensory experience of the surrounding scenery, while promoting relaxation and connection to the outdoors. The architecture aims to integrate with the rural landscape, allowing for a space where visitors can engage with the elements both during the day and at night, enjoying vistas of the pseudo craters and Mt. Herðubreið, known as the "Queen of Icelandic Mountains."

### Materiality and Sustainability

The selection of materials underscores the project's commitment to durability and sustainability. Concrete serves as the primary structural element, engineered to withstand the region's climatic challenges while offering a modern appearance. Andesite is incorporated in areas where the concrete is etched back, visually reconnecting the architecture to the earth. Over time, grass will grow over some concrete surfaces, symbolizing nature's reclamation of the site. Additionally, the design utilizes geothermal energy for operational functions, integrating sustainability into its core.

### Spatial Organization and Interaction

The spatial layout comprises essential areas such as a central common spa, a dedicated beer spa, and a café/bar, which encourage fluid movement and interaction among visitors. The raised concrete sections create terraces that enhance outdoor engagement and perspectives of the surrounding landscape. The architecture prioritizes interaction with nature by utilizing glass panels that maintain sightlines to the environment, fostering an immersive experience characterized by natural ventilation and the gradual encroachment of local vegetation on the structural components.
