Constructed with sustainable timber and rammed-earth foundations, the structure's canopy-like design offers a unique vantage point while providing a safe route for visitors to engage with the surrounding forest ecosystem.
5 key facts about this project
01
Constructed with cross-laminated timber panels to enhance structural durability and reduce carbon footprint.
02
The incorporation of charred wooden shingles provides natural fire resistance and a distinctive aesthetic.
03
A bent A-frame design not only supports the structure but reduces wind load effects effectively.
04
The structure features a modular assembly method for efficient transportation and on-site construction.
05
Designed to harmonize with its environment, it minimizes disruption to local wildlife movement.

## Project Overview

Located within a forested area, the Green Bridge-Tower is designed to enhance user interaction with its natural context through a dual-function structure that serves as both a bridge and a viewing tower. The primary objective is to create an accessible and sustainable environment that accommodates pedestrians and wheelchair users, allowing them to engage with the landscape in a meaningful way. The project incorporates eco-friendly materials and modular construction techniques, reflecting a commitment to environmental stewardship and inclusivity.

### Structural Design

The integral components of the structure—the bridge and the tower—feature a gradient design that promotes easy navigation while aligning with the topography. The bridge is inclined at a five-degree slope, ensuring accessibility for individuals with mobility challenges. The tower employs a modular approach, wherein prefabricated segments facilitate efficient assembly on-site. This method not only streamlines the construction process but also minimizes waste, reinforcing the project's sustainability goals.

### Material Selection

Timber is the primary construction material, chosen for its low carbon footprint and local heritage within Latvia's architectural practices. Its aesthetic qualities and structural capabilities enhance the overall design. Connection joints, crafted from composite materials, provide stability while optimizing resource use. Additionally, the design may integrate complementary materials, such as metal brackets and glass panels, to support functionality and durability without compromising ecological integrity.

Throughout its design, every aspect of the Green Bridge-Tower prioritizes the interaction between users and the natural environment, ensuring that the structure is both practical and harmonious with its surroundings. The emphasis on accessibility and biodiversity throughout the design further aligns with contemporary architectural standards for sustainability and user experience.

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.
