Harnessing Geothermal Energy with Skylights and Stack Ventilation in a Sustainable Dining Experience

Project in-detail

Geothermal energy powers a thoughtfully designed space that combines a Restaurant and Greenhouse, utilizing skylights and stack ventilation to enhance sustainability and food production.
5 key facts about this project
01
Geothermal systems provide energy for heating and cooling.
02
Stack ventilation enhances natural airflow throughout the spaces.
03
Skylights are designed to frame the night sky and reduce energy use.
04
The layout facilitates a direct farm-to-table experience for guests.
05
Sustainability principles guide the design, minimizing environmental impact.

The design in the Myvatn region of Iceland explores the relationship between the landscape and the culinary experience through the integration of a Restaurant and Greenhouse. It focuses on sustainability and the unique geological features of the area, illustrating how food is produced and consumed. The layout is carefully structured to provide both distinct and interconnected experiences, guiding visitors to appreciate the connection between growing food and enjoying it as a meal.

Design Concept

At the core are two separate spaces: the Restaurant and the Greenhouse. Each functions independently, yet their forms engage in conversation with each other. This interplay encourages exploration of the site. The layout groups areas into two categories: the Green, for circulation between the greenhouses, and the Red, which includes the Food & Beverage sections. This arrangement simplifies movement and enhances the understanding of how food travels from the greenhouse to the dining table.

Sustainability and Environmental Engagement

The design places a strong emphasis on sustainability. Natural airflow is optimized through stack ventilation, which reduces reliance on mechanical systems. Skylights are skillfully positioned to capture natural light while framing the night sky. This connection between inside and outside not only brightens the spaces but also enhances the experience of being in such a beautiful location. Nature becomes part of the architecture, contributing to the overall atmosphere.

Lighting Strategy

A careful lighting strategy was implemented to protect the dark sky of the region. Illumination is directed downwards, minimizing light pollution. This approach highlights a commitment to environmental balance while respecting the area's night environment. Each architectural decision aligns with the surrounding landscape, reinforcing the responsibility to both the ecosystem and the local community.

Using local materials emphasizes the idea of sustainability and helps reduce transportation emissions. Every element supports the notion that architecture can fulfill practical needs while offering insights into food systems. The form of the Restaurant and Greenhouse stands out against the landscape, showcasing the relationship between the built environment and nature, while the design of the skylights captures the changing light throughout the day in a dynamic and engaging way.

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.
