Prism Tower With Steel Structure Framing A Cave Auditorium Experience

Project in-detail

The prism tower, framed by a steel structure and designed with openings that capture the landscape views of Hverfjall and Grjótagjá, offers a unique cave auditorium experience while engaging visitors in a multifunctional cultural space.
5 key facts about this project
01
Prism-shaped tower frames views of Hverfjall and Grjótagjá.
02
Cave auditorium is intentionally buried to enhance acoustic qualities.
03
Entry space floats above the ground, creating a distinct threshold.
04
Sunken plaza connects multiple functional areas for community engagement.
05
External openings allow natural light while providing framed landscapes.

The design is situated near notable geological features, Grjótagjá cave and Hverfjall volcano crater. It functions as a multifaceted building that integrates into its natural environment, enhancing the connection between construction and landscape. The concept promotes a spatial experience that reflects the site's geological character, inviting visitors to engage with the surrounding nature while providing a welcoming atmosphere.

Structure and Entry Experience

As visitors begin their approach, they see an elevated entry space that appears to float above the ground. This design creates a clear separation between the landscape, often marked by harsh conditions, and the warmth of the interior. The façade is directed toward Grjótagjá, framing views of the geological formations and allowing natural light to enter, contributing to an inviting space.

Internal Spatial Layout

Inside, the building encompasses various functional areas, including a front desk, gift shelves, a bar, and an event space on the entry level. Visitors transition into a cave-like cinema auditorium, intentionally placed below ground, which fosters a direct link to the local geology. This arrangement highlights the contrast between the bright entry space and the darker qualities of the auditorium, offering an immersive experience for those inside.

Prism Tower and Viewing Platform

A notable feature is the prism-shaped open-air tower, incorporating stairs, auditoriums, and a viewing platform. The structure has several openings in its opaque exterior, which frame views of nearby landscape features like Hverfjall and Grjótagjá. The top opening invites natural light in, while at night, it highlights the building by casting artificial light into the sky, making it visible among the surroundings.

Material Choices

The project uses steel for structural elements, ensuring durability and support. Glass is prevalent in the façade, creating unobstructed views and maintaining a connection between internal spaces and nature. Local gravel serves practical functions as a filtering layer on the roof and for finishing the paths around the building, tying the structure to the site's geological features.

The transition from the ground to the entry space creates a sculptural form that mimics the surrounding geological profile.
