Larch and Glass Greenhouses Supporting Hydroculture in Geothermal Landscape

Project in-detail

Constructed with larch and glass, the greenhouses harness geothermal energy and hydroculture to create a sustainable food source in the challenging climate of Mývatn, Iceland.
5 key facts about this project
01
Constructed in a geothermal region, the project effectively uses natural heat for plant growth.
02
Multiple micro-climates are created within the greenhouses to support various crops.
03
Larch timber is utilized for flooring, enhancing thermal insulation and durability.
04
A hydroculture system minimizes water use while maximizing crop yield.
05
The design includes observation areas to engage visitors with the growing process.

The Green Oasis project is located near Mývatn in Iceland, a region known for its geothermal activity and its appeal to tourists. The main goal is to create a self-sustaining environment that uses the challenging climate to support the growth of plants. By designing an oasis-like space, the aim is to promote agricultural productivity alongside a deeper connection between people and nature.

Design Approach

The layout consists of three greenhouses arranged to make the most of sunlight while reducing the impact of strong winds. Each greenhouse is designed to create its own micro-climate, which helps grow a variety of herbs, fruits, and vegetables. This arrangement not only increases the efficiency of food production but also enhances the site's visual identity. The shadows cast by the structures help to define outdoor spaces, inviting exploration.

Focus on Sustainability

Sustainability is a key aspect, with the use of a hydroculture farming system that minimizes water waste and energy consumption. This system fits well with Iceland's commitment to renewable resources. Geothermal heating, drawn from the area’s natural elements, ensures optimal conditions for plant growth. In addition, solar panels are included to harness sunlight and support the project’s energy needs.

Material Choices

The greenhouses feature glass panels that allow natural light to reach the plants effectively. The exterior is outfitted with photovoltaic aluminum RHS to create a stable structure while collecting solar energy. Inside, 4 mm sheet steel adds strength against the area's tough climate. The floors are made of 25 mm larch tongued and grooved boards, designed for temperature control and moisture management.

The integration of functional farming areas and shared spaces encourages visitors to engage with their surroundings. The reflections of the greenhouses can be seen in the landscape, while the vibrant plant life being cultivated adds color and life. This design emphasizes the importance of connecting architecture with the natural world.

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.
