Inflatable units crafted from polycarbonate and wood create a flexible, sustainable shelter solution for trekkers in the challenging environment of the Himalayas.
5 key facts about this project
01
Inflatable units allow for rapid assembly and disassembly in variable terrains.
02
Hydrothermal heating uses waste heat from cooking to warm communal spaces.
03
Modular design accommodates varying group sizes and promotes community engagement.
04
Sustainably sourced wood enhances structural insulation and environmental performance.
05
Air-filled insulation layers improve thermal efficiency in extreme cold conditions.

### Project Overview

"Many Airs as One" is designed for high-altitude trekkers in the Himalayas, focusing on providing shelter, sustenance, and safety in challenging environmental conditions. The project emphasizes sustainability, community engagement, and adaptability, addressing the unique requirements of outdoor enthusiasts traversing one of the world's harshest terrains. By utilizing innovative design strategies, the structure aims to facilitate both individual comfort and communal interaction.

### Spatial and Thermal Strategy

The design incorporates a series of interconnected inflatable units termed "Air Huts," which can function independently or combine to form larger shelters. This modular approach allows for shared thermal properties, optimizing insulation and warmth in temperatures that often plunge below freezing at altitudes exceeding 4,000 meters. Consequently, the layout promotes social gathering by centralizing communal spaces, such as a kitchen area, which serves as a heat source and a hub for interaction. Individual accommodations reflect a balance of privacy and communal experience, with sleeping units designed for efficient thermal insulation.

### Material Application

The selection of materials is crucial for addressing high-altitude challenges. Key components include polycarbonate film for its lightweight and weather-resistant qualities, sustainably sourced timber for structural support, and multiple air-filled layers to enhance thermal performance. Additionally, the design integrates a heating system that utilizes hot water pipes to circulate warmth from the kitchen to living spaces. This combination of materials not only ensures durability but also contributes to the overall efficiency and comfort of the units, adapting effectively to the extreme elements of the Himalayan environment.

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.
