The setting of Aokighara Forest, known as the Suicide Forest, serves as a backdrop for an installation that deals with deep issues of mortality and rebirth. The design aims to create a space for individual reflection and support, where visitors can engage meaningfully with their inner struggles. Combining natural surroundings with thoughtful architecture, the project offers a unique environment for contemplation and connection.

Functionality and Experience

Upon arrival, visitors encounter representations of souls bathed in orange light, which symbolize compassion and warmth. Each person receives a backpack filled with items associated with suicide—pills, a knife, and a gun. This choice of items acknowledges the realities that many face and creates an opportunity for personal introspection.

Spatial Arrangement

Visitors ascend to treetops via a ladder, which signals a movement from the everyday world to a more serene experience. At the top, individuals spend their last night in an inflatable air capsule. Here, they are enveloped in the harmonic chants of Buddhist monks, intended to resonate within their minds and encourage a reconsideration of their circumstances.

Sustainability and Materials

Sustainability is an essential aspect of the design. The installation operates independently, utilizing water collection systems and solar panels placed on the tree canopies. Local wood is used for the Buddhist room, adding a natural warmth to the setting. The tents are made from compostable materials, promoting a cycle of life. If a visitor chooses to end their life, these tents will decompose and nourish the earth, allowing new trees to emerge and reinforcing the theme of regeneration.

Design Nuances

Every element of the installation is carefully designed to enhance the user experience. The arrangement offers a balance of solitude and contemplation, encouraging a deep engagement with personal feelings. Natural light filters through the trees, creating a calming atmosphere that supports reflection. Ultimately, the space serves as a poignant narrative about life and death, while also emphasizing the possibility of renewal through nature.

Vancouver Tall Challenge: Building Higher Downtown

`
Competition organisers

The Vancouver Tall Challenge: Building Higher Downtown is an international architecture competition organized by Buildner in collaboration with the City of Vancouver and the University of British Columbia’s School of Architecture and Landscape Architecture (SALA). The competition invites architects, designers, planners, and creative thinkers to explore innovative approaches to tall buildings in Vancouver’s downtown core, focusing on sustainability, livability, urban density, public space, and the city’s strong connection to nature. As Vancouver continues to grow, participants are challenged to rethink how vertical development can enhance urban life and contribute to a more vibrant, inclusive, and resilient city identity.

The competition offers a total prize fund of $15,000 CAD, with winning proposals selected by an international jury of architects, planners, academics, and city-building professionals. Key dates include the final registration deadline on October 29, 2026, submission deadline on November 30, 2026, and winners announcement on January 26, 2027.
