The project in Iceland showcases a thoughtful relationship between architecture and the natural landscape, particularly emphasizing the unique characteristics of lava fields and volcanic formations. The design focuses on blending built spaces with their surroundings, encouraging exploration and interaction. It serves multiple functions, including a museum and a café, and incorporates elements that enhance the experience of being in this remarkable environment.

Site Integration

The building is positioned at an angle to the main access road, increasing its visibility as it leads visitors from the lava fields into a defined architectural space. This thoughtful placement allows for optimal views of the Hverfjall volcano and the Northern Lights, guiding individuals toward an engaging experience as they approach.

Entrance and Experience

A half dome marks the entrance, creating a welcoming threshold that invites visitors inside. This design simulates the feeling of entering a volcano, enhancing the overall experience. The entrance area provides direct access to the various functions within the building, while a ramp leads up to the roof, allowing visitors to connect with the expansive landscape around them.

Interior Configuration

Inside, the structure features several domes of different sizes, which provide spaces for various activities. This arrangement promotes an easy flow of movement throughout the building, allowing visitors to engage with both the architectural spaces and the outdoors. Transitional areas between the domes create a blend of intimate and expansive experiences, reinforcing the connection to the natural environment outside.

Materiality and Detailing

The project utilizes concrete and lava stone, tying the design to the volcanic geology of the region. These materials lend structural support, while also reflecting the unique character of the landscape. Terrazzo adds a tactile quality to the interior, contributing to the overall narrative of the space and enhancing the sensory experience of those who enter.

The design path culminates at the café area, which is sheltered by a quarter dome. Here, visitors can relax and enjoy views of the Hverfjall volcano. This setting invites a moment of reflection, grounding the architectural experience in the context of Iceland’s rich natural heritage.
