Blackened Timber Enclosure Overlooking a Geological Chasm

Project in-detail

Erected with a blackened timber exoskeleton, the structure engages directly with its surrounding geological chasm while providing educational space for visitors to explore Iceland’s unique natural history.
5 key facts about this project
01
The building is constructed with a unique exoskeleton design resembling a whale's skeleton.
02
It includes multiple panorama windows integrated into the structure for optimal landscape views.
03
The educational space uses vitrines to display information about the surrounding geology.
04
The orientation is specifically designed to align with prevailing winds in the region.
05
Parking facilities are strategically arranged to maintain the natural integrity of the site.

The Ice Cave Tower stands across a chasm that divides two continental shelves. It is designed to fit into a rugged landscape formed by tectonic and volcanic processes. The building is both a unifying element and a marker within this complex environment. With its orientation from east to west, it responds to the prevailing winds and emphasizes a connection to the surrounding land.

Design Concept

The concept behind the Ice Cave Tower revolves around its straightforward and impactful shape. This monolithic structure’s large exoskeletal forms are made from blackened timber, reminiscent of organic structures like a whale’s skeleton. Utilizing timber aligns the building with local construction traditions while providing necessary strength. The design fosters a relationship with the environment rather than overwhelming it.

Geometric Configuration

The architecture features a double square layout, employing regulations derived from the golden section and right angles. This consistent geometric framework creates a sense of balance and proportion in the building. The elevations interact with light and shadow, blending the structure with the natural landscape and enhancing its visual appeal.

Circulation and Experience

Circulation within the Ice Cave Tower is designed for ease of movement. A ramp leads visitors up to a plateau level, allowing access across the chasm. This pathway actively engages people with their surroundings. Large panorama windows are positioned to provide views that encourage contemplation. This connection invites visitors to reflect on both the interior and the natural world outside.

Functional Engagement

Within the design, areas dedicated to education include vitrines that present information about the geological history of the site. This thoughtful inclusion enhances the visitor experience by offering insights into the landscape’s formation and significance. Parking facilities are arranged to support accessibility while maintaining the natural integrity of the location.

The upper level of the Ice Cave Tower contains a mezzanine that looks out over the cave entrance. This vantage point reinforces the connection between the structure and the topography, deepening the visitor's interaction with the land. Every design aspect is intentional, ensuring that each element serves both a practical and a visual purpose.
