Drawing inspiration from the Korowai culture, the design utilizes a towering treehouse structure to promote conservation awareness in the rapidly diminishing rainforest of Papua, serving as both an educational hub and a cultural landmark.
5 key facts about this project
01
Inspired by the Korowai people's treehouse architecture.
02
Utilizes cross-laminated timber for structural integrity.
03
Incorporates charred wooden shingles for weather resistance.
04
Features a bent A-frame design for enhanced stability.
05
Elevated viewpoints foster direct engagement with the rainforest ecosystem.

The project responds to the urgent need for ecological awareness in the face of rapid urbanization threatening rainforests, particularly in Papua, Indonesia. Designed as a tall lighthouse, it symbolizes the relationship between urban spaces and nature. The structure aims to educate people about environmental issues while reflecting the culture of the Korowai, an indigenous group known for their tree houses built in the rainforest.

Conceptual Framework

This design features a vertical layering system that imitates the natural stratification found in rainforest ecosystems. The forest canopy rises to over 130 feet, representing the thick network of leaves and branches typical of dense forests. This design choice not only adds complexity to the building's appearance but also emphasizes the connection between architectural forms and the natural environment.

Aesthetic and Structural Elements

The lighthouse is defined by shapes and forms that resemble trees, allowing it to integrate with the landscape. These organic designs help create a visual harmony with the surrounding flora. The project includes interconnected elements that mirror the relationships seen in nature, showcasing both the structural aspects of the lighthouse and the importance of ecological balance.

Cultural and Functional Integration

The influence of the Korowai culture is a key element of the design. It incorporates features from their traditional treehouse living, which protects them from the environment. This aspect of the project highlights sustainable practices based on indigenous knowledge and encourages a respectful connection between people and nature.

Elevated Interaction

The design's height not only offers views of the surrounding area but also engages city residents with the rainforest's beauty and vulnerability. This perspective allows people to consider the effects of urban growth on biodiversity and the environment.

The weathered surface treatment used for the lighthouse brings in textures reminiscent of the forest, enhancing the tactile relationship to the ecosystem while securing the structure within its natural surroundings.

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.
