Geothermal Greenhouse Featuring Etfe Canopy and Sustainable Steel Structure Enhancing Local Dining Experience

Project in-detail

Constructed with an ETFE canopy and a durable steel framework, this greenhouse restaurant utilizes geothermal energy for sustainable food production while serving as a dynamic community dining space in Iceland's unique landscape.
5 key facts about this project
01
Constructed with an ETFE canopy that enhances light diffusion and thermal performance.
02
Integrates geothermal heating to maintain a sustainable temperature year-round.
03
Utilizes a steel frame to minimize site disturbance while ensuring structural integrity.
04
Includes hydroponic gardens that support onsite food production and promote sustainability.
05
Designed with a dynamic form that mirrors the surrounding volcanic landscape.

The "circUS: Iceland Greenhouse Restaurant" is an architectural project designed to create a functional dining experience seamlessly integrated with local food production. Located in Iceland, the project harnesses the unique geological characteristics of the region, including volcanic and geothermal resources. The design melds aesthetics and practicality while prioritizing sustainability, creating a structure that supports both ecological responsibility and community engagement.

Innovative Use of Materiality and Form

One of the project’s distinguishing features is its use of materials that promote sustainability and energy efficiency. The main structure combines an ETFE membrane and glass to maximize natural light while maintaining thermal performance. This combination reduces energy consumption by optimizing the greenhouse effect within the building. The steel framework provides structural support with minimal environmental impact. Concrete forms the foundation, ensuring stability while enabling the incorporation of green elements.

The building's design reflects organic forms, mimicking the surrounding landscape. This connection to the environment is evident in its undulating shape, which aids in thermal regulation and enhances visual interaction with nature. Large glass panels allow diners to engage with the outdoor environment while enjoying their meals, fostering an appreciation for the local ecosystem.

Integrated Community and Food Production Spaces

The project emphasizes community interaction through its spatial organization. It features distinct areas including a dining hall, multi-purpose event spaces, and integrated gardens. The dining hall serves as the focal point, enriched by the proximity to the greenhouse elements that provide fresh produce directly to the kitchen. This direct connection from production to consumption is a significant aspect of the restaurant’s concept.

The design also accommodates flexible usage of space, allowing for various community-oriented functions such as educational workshops and local markets. This adaptability enables the project to serve as a hub for sustainable practices, fostering awareness and collaboration among local residents.

Sustainable Practices and Performance

A critical aspect of the "circUS" project is its commitment to sustainability through the integration of geothermal heating systems and water-efficient practices. Utilizing local resources reduces the ecological footprint while providing a comfortable indoor environment year-round. The architectural choices reflect a comprehensive understanding of the climatic conditions, ensuring that the building maintains energy efficiency throughout its lifecycle.

In summary, the "circUS: Iceland Greenhouse Restaurant" stands out for its thoughtful integration of architectural design, materiality, and functional community spaces. The project not only addresses dining needs but also enhances local food production, education, and ecological awareness.

`
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.
