### 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.

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.
