Engaging with Tectonic Cracks Through Concrete and Steel Observation Structures

Project in-detail

Positioned along a tectonic crack, the design utilizes concrete and steel to create an observation structure that fosters visitor engagement with the striking geological landscape while serving as a functional center for information and relaxation.
5 key facts about this project
01
Located on a tectonic crack between two continental plates.
02
Observation platform elevates visitors to 18 meters for expansive views.
03
Design embodies themes of imperfection and Wabi-Sabi philosophy.
04
Pathways constructed from durable concrete slabs link key features.
05
Functional annex includes a café, enhancing visitor engagement.

The Cracked Tower is located in a dramatic landscape defined by the Grjotagja caves, situated on a tectonic crack between the American and Eurasian continental plates. The design invites visitors to engage with the surrounding geological features while exploring themes of imperfection. Inspired by Leonard Cohen’s reflections on the beauty of flaws, the structure serves both as an observation point and a functional space for visitors.

Design Concept

The design takes a straightforward geometric form that connects with the natural characteristics of the site. This approach allows the structure to sit comfortably within its rugged environment while also reflecting the themes of imperfection. The tower’s shape echoes the crack in the landscape, creating a relationship with the environment and enhancing the experience for visitors who interact with the geology of the area.

Functionality and User Experience

The tower includes an annex that serves multiple purposes. There is a café and an information center designed to inform and accommodate visitors. Facilities such as restrooms are provided for convenience. An observation platform, positioned at a height of around 18 meters, offers views of the striking landscape and geological formations. It encourages visitors to connect with their surroundings in an intimate way.

Materiality

The project uses concrete for the tower’s skin and pathways, reinforcing its relationship with the volcanic rock found in the landscape. The structure is supported by a steel frame, which allows for prefabricated components that simplify construction. Prefabricated concrete slabs are used for the façades and the foundation, ensuring that the assembly process is efficient and minimizes the environmental impact.

Accessibility and Pathway Design

Well-defined pathways connect the tower to key natural features, such as the caves, allowing visitors to explore the area easily. These pathways, built from concrete slabs, ensure a straightforward way to navigate the terrain while enhancing the overall experience of visiting the site.

The observation platform provides panoramic views that highlight the unique geological formations, reinforcing the connection between the tower and the natural landscape.

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.
