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

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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
