A mobile eave system enhances solar access and rainwater collection in a low-cost prism structure, constructed with cross-laminated timber and microcement, providing efficient residential space.
5 key facts about this project
01
Mobile eave system adjusts to seasonal sunlight and weather.
02
Integrated rainwater collection system optimized for efficiency.
03
Cross-laminated timber structure enhances structural strength and sustainability.
04
Unique bent A-frame design maximizes interior space and natural light.
05
Microcement finish provides durability and a modern aesthetic.

The project showcases a thoughtful approach to sustainable design, embedded in an urban environment that balances ecological care with social value. The focus is on a low-cost prism structure that efficiently serves its function while aiming to reduce environmental impact. The overall concept blends economic factors, ecological responsibility, and social engagement, creating a coherent response to modern architectural needs.

Sustainable Design Concept

The design begins with a basic rectangular prism, modified to enhance the use of solar energy and the collection of rainwater. Lowering one vertex creates a sloped surface that maximizes sunlight exposure and facilitates water harvesting. This clever solution enhances both the building’s functionality and its appearance, allowing for seasonal adjustments in light and climate management.

Ventilation Strategy

The project emphasizes an effective ventilation strategy that promotes natural airflow. Openings are thoughtfully placed at various heights, enabling cross ventilation throughout the interior. This design choice improves indoor air quality and comfort while reducing the need for mechanical cooling. The approach aligns with sustainable design principles by fostering a healthier living environment.

Material Selection

Materials have been chosen with care, ensuring both performance and environmental responsibility. The use of aluminium roofing sheets, cross laminated timber, and rigid thermal insulation are notable choices that reflect a focus on durability and energy efficiency. The Exterior Insulation Finish System contributes to the building's overall energy conservation, while microcement flooring, reinforced concrete, and extruded polystyrene foam enhance thermal performance and longevity.

Design Outcomes

The careful selection of design elements leads to a building that meets practical needs while engaging with its environment. The result is a structure that blends well with its surroundings and speaks to its purpose. The mobile eave serves as an effective shading system and protection against rain, adapting to varying weather conditions and enriching the user experience through its responsiveness.

`
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.
