### Overview

Milestone 108 is situated in the high altitudes of the Himalayas, designed to accommodate the needs of mountaineers and trekkers in Nepal. The project seeks to integrate the physical structure with its surroundings while reflecting cultural and spiritual significance. This approach aims to create a space that serves not only as a shelter but also as a sanctuary for reflection and connection with nature.

### Spatial and Functional Organization

The design consists of a three-tiered structure that includes a ground floor, first floor, and second floor, each serving distinct purposes. The ground floor features an entrance area equipped with sanitary facilities and storage for expedition gear, acting as a buffer against the elements. The first floor encompasses communal areas such as a common room and kitchen, fostering interaction among visitors and enhancing the sense of community. On the second floor, a dormitory accommodates up to 17 individuals, designed for flexibility and comfort, allowing for easy rearrangement of sleeping arrangements.

### Material Strategy and Sustainability

The choice of materials emphasizes sustainability and suitability for the harsh Himalayan environment. Structural elements primarily utilize wood for insulation and warmth. Durable corrugated steel sheets form the façade, while insulation materials ensure a stable internal climate. The incorporation of solar panels and wind turbines highlights a commitment to renewable energy, essential for self-sufficiency at high altitudes. Additionally, large windows enhance natural light and provide panoramic views, reinforcing the connection to the breathtaking landscape. These material selections collectively contribute to a resilient structure that respects traditional building techniques.

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.
