A Double-Skin Cubic Structure Featuring Translucent Polycarbonate and Local Timber

Project in-detail

Incorporating a double-skin facade of translucent polycarbonate and locally sourced timber, the structure harmonizes with the volcanic landscape while providing essential facilities for winter recreation.
5 key facts about this project
01
Utilizes a double-skin façade for enhanced thermal insulation and light penetration.
02
Integrates locally sourced timber, supporting regional sustainability efforts.
03
Features large windows designed specifically for unobstructed views of the Northern Lights.
04
Incorporates geothermal systems for efficient heating and hot water.
05
Designed as a cubic structure to blend seamlessly with the volcanic landscape.

The Ice-Cube Cabin, situated in Iceland's Krafla Crater, is designed to provide essential recreational and functional facilities for visitors within a landscape defined by volcanic and glacial features. The project prioritizes sustainable design principles to minimize environmental impact and respect the local cultural heritage, offering a contemporary architectural solution attuned to its unique context.

Spatial Strategy and Functionality

The cabin's design incorporates a double-skin facade, utilizing translucent polycarbonate and locally sourced timber, to enhance thermal performance and echo the geological strata of the surrounding environment. This design strategy ensures a comfortable interior climate during severe winter conditions while maximizing energy efficiency.

The cabin is spatially organized into two levels to optimize functionality. The ground level comprises an entry hall, information center, changing facilities, equipment storage, and rest areas. The upper level features a viewing platform and supplementary rest amenities, enhancing visitor engagement with the exterior environment.

Materiality and Sustainability

In alignment with environmental strategies, the cabin emphasizes the use of sustainable materials, including locally sourced timber, to ensure durability and minimize ecological footprint. Translucent polycarbonate panels are employed to maximize natural light penetration while preserving privacy, thereby reducing energy consumption. Geothermal energy systems are integrated to provide efficient heating and hot water, capitalizing on the region's natural geothermal resources. This integrated approach, combining local materials and advanced technologies, represents a considered architectural response to the region's unique and dynamic climate.

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.
