Steam-Driven Thermal Comfort with Tectonic Interactions

Project in-detail

By integrating steam-driven thermal comfort with the natural movement of tectonic plates, the design creates a responsive environment that cleverly collects precipitation while serving various recreational functions.
5 key facts about this project
01
Utilizes the natural movement of tectonic plates for structural dynamics.
02
Employs a steam-driven system for heating and moisture management.
03
Features a dual-function setup where one building releases steam and the other collects water.
04
Incorporates an underground water distribution network based on flow rates.
05
Creates an evolving landscape that changes with each visitor experience.

The design near Mývatn, Iceland, engages with the region's geothermal resources and unique geological features. It emphasizes the use of underground assets to draw attention to the natural landscape rather than changing it drastically. The aim is to create a space where the building interacts with the environment, shaped by the continuous movement of two tectonic plates that are ever so slowly drifting apart.

Geothermal Resource Utilization

Central to the design is the focus on geothermal energy. By tapping into the abundant resources beneath the surface, the building minimizes its impact on the landscape while celebrating its natural elements. Steam serves as a primary heating source, with pipes carefully placed throughout the interior. This method not only ensures warmth but also adds an interesting visual aspect to the overall design.

Water Management Strategy

The design includes a detailed underground water distribution system that sorts areas based on their flow rates. High flow sections are intended for essential functions like transportation and parking. Moderate flow areas accommodate recreational activities, such as camping and hot springs, while low flow sections manage local roads and trails. This thoughtful organization reflects a keen awareness of the site’s water resources and promotes responsible use.

Structural Dynamics

The arrangement of the buildings demonstrates an innovative understanding of structural dynamics. Wires connecting the two structures adapt to the movements caused by tectonic activity. A screw system helps regulate steam release, allowing one building to exhale steam while the other collects rainwater. This relationship creates a continuous interaction between the two, fostering a symbiotic environment that evolves gracefully over time.

An important detail is the network of visible steam pipes that crisscross the surfaces. These pipes facilitate the condensation process that generates precipitation. Water collected from this system is reused, showcasing a practical, sustainable approach while emphasizing the connection between architecture and natural processes.

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.
