## Overview

Located near the Skútustaðagígar craters in Iceland, the Beer Spa project integrates architectural design with local culture and the natural landscape. This facility serves not only as a place for brewing but also as an immersive experience that engages visitors with both the brewing process and the surrounding environment.

## Spatial Organization and Unique Features

The Beer Spa is organized into three primary levels, each designated for specific functions while maintaining interconnectivity. The ground floor houses the brewery and a souvenir shop, where large glass windows provide visibility into the brewing process. The first floor features a beer spa lounge, complemented by a terrace that offers expansive views of the craters, providing an area for relaxation and various treatments. A gallery space dedicated to educating visitors about the brewing process links the visual journey of the facility to its production mechanisms.

One of the defining architectural elements is the “second skin” facade, which serves both aesthetic and functional purposes. This outer layer provides protection while facilitating air circulation, essential for maintaining the spa environment. The spatial layout promotes active engagement, with a winding path that simulates the brewing process and leads to the spa lounge, fostering an intimate connection between architecture and experience. The presence of outdoor terraces enhances interaction with the landscape, allowing guests to appreciate the unique geological features of the area, while the interplay of open and enclosed spaces dynamically shifts light and shadow, enriching the sensory experience within.

## Materiality

The material selection plays a critical role in the project’s identity. Predominantly using slatted timber for the facade, the structure evokes warmth and reflects the natural textures of the landscape. Strategically placed glass elements enhance natural light flow and visibility into brewing activities. Internally, natural stone elements ground the design, drawing inspiration from Iceland's volcanic geology, while steel structures balance strength and modernity. Concrete provides robust support for the facility. Nuanced lighting, including LED installations, enriches the experience by creating varying atmospheres that adapt to different moments of the day.

`
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.
