## Project Overview

Located near Myvatn Lake in Iceland, the Myvatn Grotto embodies a spa design that engages directly with the region’s geothermal and volcanic landscape. The intent is to create a facility that fosters a connection to water and nature, offering visitors a range of therapeutic experiences. This architectural solution integrates natural elements with modern design to enhance the user experience.

## Spatial Organization and Interaction with Water

The spatial composition consists of interconnected areas, each serving distinct purposes while allowing for a fluid transition between environments. Water pathways function both as experiential routes and environmental filters, guiding visitors throughout the facility. The tiered layout creates a dynamic relationship between the interior spaces and the natural surroundings, simulating the meandering flows of water bodies.

Water features are a prominent aspect of the design, incorporating pools, steam rooms, and waterfalls that emphasize the soothing and revitalizing properties of water. The architecture encourages active engagement with these elements, promoting awareness of the physical and mental health benefits attributable to water.

## Materiality and Sustainability

The design employs a diverse range of materials chosen for their structural integrity and resonance with the local environment. Concrete provides durability, while large glass panels maximize natural light and facilitate indoor-outdoor connectivity. Steel supports the building's modern aesthetics, and copper panels enhance the façade's visual appeal through natural aging.

A sustainable approach informs the selection of resources, with an emphasis on local materials and environmentally conscious construction practices. The integration of geothermal heating and stormwater management systems demonstrates a commitment to ecological sustainability, further enhancing the building's functionality and responsibility toward the environment.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
