The Iceland Greenhouse Restaurant is located in the picturesque area of Mývatn, Iceland. It serves as both a dining venue and a greenhouse space where visitors can enjoy meals surrounded by nature. The design centers on a concept called the "frozen ribbon," which creates a protective cover while framing views of the striking Hverfjall volcano and the tranquil Mývatn lake. This structure connects the restaurant with the landscape, offering a unique experience for guests.

Design Approach

The layout of the restaurant is organized to create different dining experiences. It includes large communal tables that encourage social dining, intimate settings for smaller groups or families, and a bar area linked to a lounge. This variety of spaces allows guests to choose their preferred atmosphere, enhancing the overall experience while remaining close to nature.

Spatial Organization

The building adapts to the topography of the site. Social spaces are placed in the lower southern area while greenhouse elements occupy the higher northern section. This configuration minimizes disturbance to the land and optimizes natural light and views. Open staircases and vertical green walls facilitate movement through the space, integrating elements of nature within the architecture.

Materiality

The structure uses galvanized steel columns that provide stability and strength. Laminated Veneer Lumber (LVL) beams are included to offer warmth and a natural aesthetic. The lower façade is made of glass with aluminum framing, allowing for expansive views and abundant daylight. The upper layer is crafted from multi-wall polycarbonate sheeting, which helps manage heat and light within the building.

Sustainability Considerations

Attention to sustainability is apparent throughout the design. A geothermal heating system draws on local thermal water sources, providing an efficient way to heat the building. The restaurant also includes facilities for organic waste recycling, highlighting its commitment to environmental responsibility.

Guests are surrounded by vibrant greenery while dining, enhancing the atmosphere with a sense of peace and connection to the outdoors. This integration of nature and dining creates a remarkable setting for both locals and visitors to enjoy.
