## Overview

The Sel Crater Retreat is located in Myvatn, Northern Iceland, in proximity to Sel Hill and Lake Myvatn, an area renowned for its geothermal activity and natural beauty. The retreat aims to create an immersive experience for visitors by integrating architectural design with the surrounding landscape. The design reflects the unique topography of the region, fostering a connection between guests and their environment while prioritizing functionality and aesthetic appeal.

## Spatial Configuration and User Interaction

The architectural response to the site's natural geometry is characterized by an undulating roof that mimics the contours of the surrounding hills. This curvilinear design not only enhances structural stability but also creates a welcoming atmosphere that encourages interaction with the landscape. The interior features an open-plan layout that prioritizes communal spaces, facilitating social engagement among guests. Large glass windows throughout the retreat allow abundant natural light and provide expansive views, further enhancing the experience of relaxation and rejuvenation.

## Material Selection and Sustainability

The choice of materials plays a crucial role in reinforcing the retreat's relationship with its environment. Timber serves as the primary material for the roof structure and interior finishes, chosen for its durability and lightweight properties. Extensive use of glass enhances visual connections to the outdoors, while a steel framework provides structural support. Concrete ensures stability in the geological context, complemented by laminated wood for the roof’s complex shapes. Local stone may be integrated into the design, further anchoring the retreat in its landscape. The inclusion of geothermal heating systems aligns with sustainable practices, underscoring the project's commitment to environmental responsibility.
