Cave Tower Featuring Timber Climbing Courtyard and Geological Observation

Project in-detail

The cave tower's timber climbing courtyard embraces the geological fissures of Iceland's landscape, offering visitors a unique vantage point to explore the surrounding natural beauty and observe the geological formations.
5 key facts about this project
01
Cave tower designed to harmonize with geological fissures.
02
Timber climbing courtyard enhances visitor interaction with the structure.
03
Elevated sections maintain unobstructed views of surrounding landscapes.
04
Custom timber modular grid ensures lightweight and sustainable construction.
05
Geothermal energy potential integrated within the building's design.

"The Upside Down" is an architectural design that creates a relationship between structure and landscape. Set in a location marked by significant geological features, it features a cave tower that serves both as a viewpoint and a destination for visitors. The design aims to enhance the experience of the natural environment, encouraging exploration and interaction with the surrounding landforms.

CIRCULATION AND ACCESS

The design incorporates two main ways for visitors to move through the space. One option is a continuous ramp leading to an observation dock, making it accessible for everyone. The second choice involves a climbing path built into the cave tower, adding an adventurous element to the experience. This climbing area allows visitors to engage more deeply with the cave-like structure and connect with the geology of the site.

SPATIAL DYNAMICS

The building is divided into two blocks, representing the geological separation found in the area. This division creates interesting spatial relationships that offer different experiences at each level. Elevated sections of the tower are designed to maintain clear views of the surrounding landscape. Sightlines to landmarks such as the Hervfjall volcano and Maylatain lake are preserved, enhancing visitors' appreciation of the region's natural beauty.

STRUCTURAL INNOVATION

The choice of a customized timber modular grid for the structure supports both sustainability and design flexibility. This system allows for the use of smaller, lighter components, making construction more efficient. Choosing wood aligns with modern efforts to use environmentally friendly materials, strengthening the project's connection to its surroundings.

The design also incorporates environmental strategies that address the site's geological context. High annual humidity levels create opportunities for using atmospheric water generation and exploring geothermal energy. These elements reinforce the building's fit within the local ecosystem.

At the heart of "The Upside Down" is an invitation for visitors to explore a compelling narrative with the earth. As they ascend through the cave tower, they are surrounded by deep views of the dramatic Icelandic landscape, resulting in a memorable experience of place and nature.

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.
