Incorporating Werregue weaving and a permeable membrane, the tower elevates living spaces above flood risks while serving as a community hub to promote sustainable practices in the mangrove ecosystem.
5 key facts about this project
01

02
Utilizes local Werregue weaving techniques for façade design.
03
Features a permeable membrane made from renewable vegetable materials.
04

The design focuses on a tower located in the mangroves of Buenaventura, Colombia. Its main purpose is to restore the relationship between human habitation and the natural environment. The tower acts as a community space while addressing important issues such as illegal wood trafficking. By using principles from vernacular architecture, the design integrates with the unique features of the mangrove landscape.

Site Context

The tower is positioned on Cangrejo Island, which is 1.7 kilometers from the urban edge. This location allows for effective monitoring of timber traffic, highlighting the importance of environmental governance. The site's characteristics have greatly influenced the design and the various functions of the tower. The aim is to create a structure that complements the natural surroundings while serving the community's needs.

Structural Organization

The design incorporates stilt structures that elevate living spaces above the risk of flooding. This is a necessary response to the water dynamics found in mangrove ecosystems. The central tubular system provides a large void, with beams connecting the outer walls and supporting the structure. This organization enhances the tower's strength and facilitates better load distribution.

Cultural Integration

The façade of the tower draws from local Wounaan culture, specifically referencing traditional Werregue weaving techniques. This choice not only adds aesthetic value but also connects the architecture to the local community. A permeable membrane made from renewable vegetable materials is used to promote sustainability. It protects against moisture and sunlight while being easy to maintain.

Programmatic Elements

The tower includes spaces that encourage community engagement and education. It features workshops for carpentry and canoe repair, promoting local skills and traditions. Educational facilities focused on sustainable fishing practices further enhance community involvement. Additionally, spaces like a hostel and communal areas provide economic opportunities while educating visitors about the environment.

The intricate façade showcases woven patterns that represent local craftsmanship, establishing a connection between the tower and its natural surroundings. This blend of architecture and culture creates a distinct identity that resonates with the landscape.

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.
