Emphasizing a curvilinear ramp and modular footbridge, the observation structure utilizes sustainable fir and OSB to create an accessible vantage point that enhances interaction with the natural landscape.
5 key facts about this project
01
Utilizes a curvilinear ramp design for seamless accessibility.
02
Constructed using sustainable fir and OSB for durability and ecological sensitivity.
03
Features a modular footbridge that connects to surrounding pathways.
04
Incorporates panoramic viewing platforms on each level to enhance experience.
05
Designed with a focus on integration into the natural landscape.

## Project Overview and Context
The observation tower is located within a landscape characterized by proximity to forests and wetlands, designed to enhance the visitor experience through an engagement with nature. The intent is to create a functional structure that serves as a focal point for outdoor activities and exploration, contributing to the site's value as a recreational destination.

## Structural Complexity
The design incorporates a robust structural framework composed of wood beams and circular piers, ensuring both stability and visual appeal. It features three distinct levels arranged to optimize views and facilitate movement. A curvilinear ramp provides a gentle ascent, enhancing accessibility for all users, including those with mobility challenges. The use of a plug-in construction method allows for quick assembly and adaptability, reinforcing the tower's role as a modern architectural solution.

## Material Selection and Sustainability
Material choices are integral to the project's efficacy, balancing aesthetic qualities with structural requirements. Fir wood beams form the primary support, offering both robustness and warmth, while oriented strand board (OSB) is utilized for ramps and flooring, ensuring durability and cost-effectiveness. Metal coupling devices enhance structural connections, promoting both stability and flexibility. Transparent wood finishes protect against environmental factors while showcasing the material's natural characteristics. The project adheres to sustainable practices by prioritizing the use of renewable materials and minimizing construction waste, ultimately reflecting a commitment to ecological responsibility.

`
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.
