The Green Cave is located in an area characterized by dramatic landscapes in Iceland, where it aims to create a unique experience centered around cinema. The project blends into the existing terrain, using underground spaces to highlight its natural surroundings. It invites visitors to explore and interact, fostering a connection between the architecture and the environment around it. The design emphasizes the importance of providing an engaging experience that encourages curiosity.

Design Approach

The architecture incorporates minimal openings that enhance a sense of intrigue while guiding visitors into the various spaces inside. These openings allow natural light to enter, creating a play of light and shadow that enriches the atmosphere. This thoughtful design not only serves aesthetic purposes but also enhances the experience for those who enter, encouraging them to appreciate the spaces more fully.

Material Expression

The building features a facade made of corrugated weathered steel, which contributes to its distinctive appearance while reflecting the local environment. This treatment of the exterior allows the structure to blend with its surroundings, providing an appealing look that is both durable and practical. The choice of materials communicates a strong connection to the natural landscape, engaging visitors from the moment they arrive.

Site Integration

Visitors access The Green Cave through a gravel driveway crafted from volcanic stone, which directs them to a sunken entry. This layout creates a sense of arrival that prepares guests for the exploration of the interior. Inside, spaces such as the lobby and restaurant flow into the main cinematic areas, promoting movement and social interaction within the building.

Viewing Experience

Above the main areas, a turf roof provides visitors with stunning views of the surrounding Icelandic scenery. This roof serves as an outdoor space that connects visitors with nature, allowing them to appreciate the landscape from a unique vantage point. This feature not only emphasizes sustainability but also enhances the overall visitor experience within the broader context of the site, offering an opportunity to engage deeply with the environment.
