The Greenhouse Garden in the Crater is located at the foot of the Hverfjall Volcano in Iceland. It combines the functions of a greenhouse and a multipurpose space. The design draws inspiration from the area's unique geography, emerging as a triangular slice of earth crust. The building features a central "crater" hall that invites visitors to engage with the stunning landscape.

Central Features

The arrangement includes a central "crater" hall that creates a welcoming atmosphere for gatherings. Visitors access the space through an entrance designed to resemble a cut into the earth’s crust. This pathway leads into a semi-underground area illuminated by a linear skylight. This feature guides people towards the greenhouse, enhancing the overall visitor experience and establishing a strong connection between indoor and outdoor environments.

Functional Design

Inside, the greenhouse occupies a prominent position within the circular hall. It benefits from natural light and geothermal heat, creating an ideal environment for growing plants. The skylight, often referred to as the "frozen ocean," infuses the space with light while supporting plant growth. This thoughtful design highlights the commitment to sustainability and ecological awareness, making the greenhouse a central element of the building.

Materiality and Aesthetic

Construction materials include fairfaced concrete and dark grey volcanic stone. Both choices echo the local geology and contribute to the building's context. Fairfaced concrete adds a modern touch, while volcanic stone connects the structure to its surroundings. Together, they create a cohesive visual appearance that enhances the relationship between the building and the landscape.

Spatial Experience

The interior includes a multifunctional restaurant and hall that provide views of the greenhouse on one side and the Hverfjall Volcano and milky blue mineral water on the other. This design invites visitors to experience nature from every angle, emphasizing the relationship between the interior and the external environment. The linear skylight not only improves visibility but also allows natural light to play across the space, creating a dynamic atmosphere.

The detailed design of the ceiling and the transparent surfaces fosters an engaging environment, inviting visitors to explore both the building and its natural surroundings.
