## Project Overview

The Conical Tower is situated in a wetland area known for its rich biodiversity and significance for birdwatching. This structure serves as both a viewing platform and a shelter, designed to enhance visitor interaction with the natural environment. The architectural concept is based on a triangular plan, culminating in a conical form that marries functionality with ecological sensitivity.

## Design Strategy

### Spatial Organization

The interior of the Conical Tower features a circular layout with multiple observation platforms connected by a central staircase. This arrangement promotes ease of movement and maximizes the views of the surrounding landscape. The structure's height varies, with the first level at 2 meters and the second at 5 meters above ground, providing unobstructed sightlines for observation.

### Material Selection

The construction utilizes locally sourced materials to minimize ecological disruption. The primary structural component is wood, with specifications including 8x8 inch wood for central pillars, 2x6 inch wood for beams, and smaller sizes for flooring. Woven vegetal textiles are employed for external cladding to enhance the integration with the environment, while steel plates are used for joints to ensure durability and stability. This combination of materials not only enhances the tactile quality of the structure but also underscores its connection to the natural surroundings.

## Environmental and Cultural Context

### Sustainability Measures

The design prioritizes sustainable practices, incorporating traditional construction techniques that facilitate natural ventilation and solar orientation. These features contribute to a comfortable indoor environment while respecting the ecological conditions of the site.

### Community and Cultural Engagement

Inspired by traditional shelters from various global cultures, the Conical Tower connects visitors to broader narratives about nature and shelter. It functions as a communal gathering point that promotes environmental education and fosters social interaction, appealing to birdwatchers, researchers, and casual visitors. Positioned within a vital ecological corridor, it facilitates discussions on conservation and the importance of preserving natural habitats.

`
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.
