Utilizing thermal water systems and incorporating the Areca plant, the design harmoniously blends agricultural productivity with community spaces for food preparation and engagement.
5 key facts about this project
01
Thermal water systems enhance energy efficiency throughout the building.
02
Greenhouse incorporates local biodiversity by allowing foreign plant growth.
03
Distinct thermal comfort zones are created using passive design strategies.
04
Community spaces are intentionally oriented to maximize sunlight exposure.
05
The design features a wall radiation system for effective heating management.

The project presents an integrated approach to functionality and sustainability within the context of agriculture. It addresses the needs of its environment while creating a balance between living and working spaces. The design focuses on thermal comfort and engages a variety of activities, showcasing how modern architecture can complement traditional practices in farming.

Thermal Comfort Zones
- Distinct thermal comfort zones are designed to cater to the different activities that take place in the building. Passive techniques such as the use of thermal water systems and specific color choices help optimize thermal conditions. Measures to protect from the elements encourage layering in clothing, which contributes to natural comfort and improved well-being for those within the space.

Spatial Arrangement
- Food preparation areas, including reception, dining, and multipurpose spaces, are positioned to make the most of sunlight. The choice of a south-facing orientation is essential for maximizing exposure to solar energy, aiding both energy efficiency and user comfort. The careful layout fosters interaction between agricultural production and daily living, enhancing the functionality of the space.

Greenhouse Integration
- The greenhouse is a prominent element that allows for growing various vegetables and flowers for the local market. This integration not only serves practical purposes but also introduces biodiversity to the area. The design is adaptable, accommodating foreign plant species even in harsher climates, which showcases its resilience and adaptability.

Ecological and Material Considerations
- Vegetation is thoughtfully chosen to enhance indoor air quality, featuring plants like the Areca and the Mother-in-Law's Tongue. These selections support a healthy indoor environment and reflect a commitment to natural design principles. Material choices, including down jackets and wool, serve to enhance warmth and comfort, acting as elements of thermal management.

Among the design details, a wall radiation system effectively increases heating surface area through a corrugated façade. This approach achieves a practical balance between environmental efficiency and occupant comfort.

`
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.
