### Project Overview

The Lookout, situated adjacent to the Duero River in Serio, Spain, functions as a center for environmental studies and education tailored for university students. It serves as a resource for academia and experiential learning, emphasizing the relationship between architectural design and the surrounding natural environment. The center's location enhances its accessibility and facilitates exploration, aligning with its educational mission.

### Spatial Organization and Experience

The design emphasizes a distinct spatial hierarchy, comprising study areas, exhibition spaces, classrooms, and observatories that promote collaboration and interaction. A central open spiral staircase allows for unobstructed movement within the building, while strategically placed openings frame views of the natural landscape. The vertical structure, with its cylindrical form, not only offers panoramic perspectives of the river but also encourages contemplative learning through diverse educational activities centered on observation and interpretation of the environment.

### Material Choices and Sustainability

Construction of the Lookout employs a selection of materials that merge contemporary techniques with traditional practices. Key materials include stone masonry for structural integrity and durability, concrete for its versatility, glass to enhance natural lighting and visual connections to the outdoors, and steel for supportive framing. This thoughtful combination reinforces the connection to local heritage and promotes sustainability by minimizing transportation needs. Additionally, the design incorporates natural ventilation, rainwater harvesting systems, and green roofing, which collectively reduce environmental impact while enriching the educational experience of the center.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
