## Modular Capsules of Nepal

### Overview
Situated in the challenging mountainous terrain of Nepal, the project addresses both geographical and climatic conditions through a modular architectural approach. Designed to adapt to the unique needs of local communities, the project utilizes a series of modular units that aim to provide functionality across various living and communal spaces. This design strategy enhances ease of assembly and ensures the structures can effectively meet diverse requirements in remote locations.

### Modular Configuration
The architecture comprises multiple unit types that serve specific functions. Key components include entrance and technical modules, sleeping modules for individual accommodation, living modules for communal activities, storage modules for personal items, medical resource modules equipped for basic healthcare needs, and service modules that provide living spaces for staff. The hexagonal module design permits flexible configurations, allowing for the creation of larger complexes while maintaining stability and aesthetic variety suited to the region's harsh weather.

### Material Selection
Material choices are focused on resilience and sustainability, responding to local climate conditions and availability. The design typically incorporates prefabricated steel or aluminum for structural stability, wood or composite panels for insulation and aesthetic integration with the natural environment, and glass elements for ample natural light and scenic views. Energy strategies include solar panels to achieve self-sufficiency and rainwater harvesting systems integrated into technical modules to provide potable water, facilitating resource efficiency and ecological responsibility.

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.
