Tetrahedral Viewpoint with Sintered Stone and Structural Glazing Over Tectonic Plates

Project in-detail

A tetrahedral structure clad in sintered stone and large-scale glazing presides over the intersection of the North American and Eurasian tectonic plates, offering visitors a unique viewpoint on the geological landscape.
5 key facts about this project
01
Tetrahedral shape enhances structural stability while integrating with the landscape.
02
Large-scale structural glazing creates a visual connection to the surrounding environment.
03
Positioned directly on the fault line between two tectonic plates for contextual relevance.
04
Bridge design avoids dependency on the North American plate, ensuring stability.
05
Sintered stone cladding contributes to durability and energy efficiency in the design.

The Iceland Cave Tower is set in the unique landscape of Iceland, where the North American and Eurasian tectonic plates intersect. Serving as both a viewpoint and a landmark, the tower is designed to reflect the geological movements occurring in the area. The overall concept emphasizes the relationship between the building and the natural forces at work, integrating it into the surrounding terrain while providing visitors with an insightful perspective on the landscape.

Geometric Form and Positioning

The tower features a tetrahedral shape that interacts with the landscape's natural contours. Positioned on the European side, it aligns closely with the fault line between the tectonic plates. The pathways leading to the entrance mimic these geological fractures, enhancing the connection between architecture and the environment. This thoughtful positioning encourages visitors to engage with the geological context, as the building appears to grow organically from the land.

Materiality and Structure

Material choices play a significant role in the design and performance of the tower. Large-scale sintered stone cladding gives the building a sturdy exterior while also contributing to its visual appeal. Reinforced concrete forms the main structure, providing necessary strength and stability. Additional materials such as mineral wool thermal insulation and XPS thermal insulation enhance energy efficiency and comfort. Concrete slabs serve as the foundation for the tower, ensuring a solid and durable base.

Integration of Glazing

Large-scale structural glazing is a key feature of the design, allowing for an abundance of natural light inside. This extensive use of glass creates a visual connection between the interior and the outdoor landscape, offering panoramic views of the geological formations. Such transparency helps to dissolve the barriers between inside and outside, making visitors feel more connected to the environment surrounding them.

Bridging Geology

A glass bridge complements the tower, spanning the gap between the tectonic plates. The design of the bridge avoids reliance on the North American plate, ensuring stability as geological shifts occur. This careful engineering provides an elevated vantage point to observe the terrain below. The bridge enhances the visitor experience, allowing for a direct engagement with the landscape and its geological features, ultimately highlighting the natural dynamics of the area.

The tower's design incorporates large openings that invite nature inside, drawing visitors into an exploration of the striking Icelandic landscape and its unique geological history.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
