Utilizing charred wood for its facade and designed to create multiple microclimates, the greenhouse serves as a dynamic community space that enhances agricultural production while fostering social interaction.
5 key facts about this project
01
Utilizes charred wood for both aesthetic appeal and thermal insulation.
02
Integrates movable planters to enhance spatial flexibility and adaptability.
03
Designed with a staggered greenhouse layout to reduce self-shading.
04
Incorporates an open southwest corner for maximum daylight entry.
05
Inspired by traditional Walipini structures to optimize passive solar energy.

The ICE Greenhouse and Restaurant is located in Iceland and designed to merge agricultural use with a community gathering space. The project aims to respond to its environment by taking advantage of the natural slope of the land. With a focus on sustainability, the design enhances sunlight exposure and fosters a connection between people and nature.

Site Orientation and Design Strategy

The layout features a long facade that faces south, encouraging maximum sunlight to enter the greenhouse. An open southwest corner allows for lower walls, which helps bring in more light and offers clear views of the landscape outside. This design promotes a strong visual link between the interior and the surroundings, inviting occupants to engage with the environment.

Structural Composition and Functionality

The structure consists of eight connected greenhouses, covering a total of 5,000 square meters. The construction is planned in phases, allowing for gradual growth that aligns with the needs of the community. Each greenhouse is staggered to reduce the chances of self-shading, creating individual microclimates that benefit plant growth. This thoughtful arrangement serves both the agricultural and communal functions of the space.

Material Selection and Aesthetic Integration

Material choices are key to the building’s performance and appearance. The exterior utilizes charred wood, which not only insulates but also harmonizes with the local volcanic landscape. Inside, exposed concrete is paired with natural wood elements, creating a balanced atmosphere that promotes comfort alongside functionality. This combination of materials supports the project’s commitment to sustainable practices.

Adaptive Design Features

Movable planters have been integrated into the design, allowing for flexibility and encouraging interaction within the greenhouse spaces. This feature aligns with the idea of adaptability, accommodating different uses as needs change over time. The planning also incorporates an analysis of sun and wind patterns, ensuring that the structure optimally captures natural light and minimizes the effects of harsh weather.

The design includes unique angles for the greenhouse sections, which maximize sunlight exposure while enhancing the connection to the surrounding landscape. This thoughtful approach creates a harmonious relationship between the spaces used for growing and those intended for community interaction.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
