The Pavilion, located near the ancient caves of Grjótagjá in Iceland, exemplifies a thoughtful connection between architecture and the surrounding landscape. It serves multiple purposes, including a cinema, a bar/restaurant, and an exposition center. The design focuses on blending with nature, aiming to minimize environmental impact while providing a welcoming space for visitors.

Site Integration

The form of the Pavilion rises gently from the ground, resembling a protective cape. This elevated design minimizes disruption to the natural surroundings and preserves the scenic beauty of the area. The building aligns itself with the contours of the nearby volcano, creating a visual dialogue with the landscape that enhances its overall presence.

Functional Layout

Inside, the Pavilion is organized into three main areas that encourage movement and interaction. The cinema acts as the central feature with walls designed to reflect themes of rock and ice. This unique shape not only adds a distinct character but also improves sound quality within the space. Adjacent to the cinema, the bar and restaurant connect through a long, glazed corridor. This transparent passage allows people to flow easily between different areas while fostering a sense of community.

Sustainability Strategies

Sustainability is a key consideration in the design, prominently featuring a green roof that contributes to energy efficiency. The choice of low-carbon concrete and wood aligns with the goal of reducing the project’s environmental footprint. Strategic roof openings are designed to maximize natural light coming in from the south, reducing reliance on artificial lighting and creating a bright, inviting atmosphere inside.

Design Details

The Pavilion is notable for its careful attention to practical details. The fully glazed foyer encourages visitors to explore both the interior and the natural beauty outside. Natural light filters in, enhancing the experience within the space. The combination of thoughtful design, material choices, and a layout that invites interaction distinguishes the Pavilion as a meaningful addition to its environment, reflecting a commitment to harmony with nature.
