Reflective Steel Structure Embracing the Landscape and Geothermal Energy

Project in-detail

The reflective steel structure, harmonizing with the surrounding landscape and harnessing geothermal energy through an innovative design, serves as a visitor center near Karlagjá cave, inviting exploration of the area's geological features.
5 key facts about this project
01
Reflective outer skin minimizes visual impact in the natural landscape.
02
Observation platform extends into the air, offering expansive mountain views.
03
Kinetic pavement tiles generate electricity from visitor foot traffic.
04
Central skylight refracts the aurora light into the interior space.
05
Built using a steel structure that integrates with local geothermal energy.

"The Gap Flower" is a structure located near the entrance of Karlagjá cave. It serves as a visitor center and embodies the relationship between the natural landscape and built forms. Designed to represent a flower rising from an icy environment, the building reflects the contrasting elements of fire and ice that characterize the region. The project enhances public interaction with the area's unique geological features.

Design Concept

The design integrates thoughtfully with the surrounding landscape. The outer surface is reflective, allowing it to blend in with the environment and minimize visual disturbance. A central skylight plays a vital role in the design by bringing natural light into the building, creating a lively interaction of light and shadow that enriches the experience for visitors.

Program and Functionality

The facility includes essential amenities for visitors. Features such as a waiting area, an information stand, storage rooms, toilets, a café, an office, and an observation platform make the space functional. The observation platform is particularly notable, extending outward to offer expansive views of the nearby geological fissures and mountains, encouraging visitors to engage with the surrounding natural beauty.

Sustainability Features

Sustainability is a key aspect of the design. Kinetic pavement tiles are used to generate electricity based on foot traffic, demonstrating an efficient way to harness energy within the building. The design also incorporates a ground source heat pump, making use of local geothermal resources to provide sustainable heating.

Material Selection

Materials used in the project include mirror stainless steel and a sturdy steel structure. These choices not only support the structural needs but also enhance the overall appearance of the building. The reflective quality of the stainless steel strengthens the connection between the structure and its natural setting, aligning with the concept of integration into the landscape.

The upper levels provide visitors with a chance to experience the interaction of light and form, creating an inviting space that encourages exploration of the area's distinctive qualities.

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.
