Utilizing bamboo and biodegradable fungi, the design creates a self-sufficient shelter that harmonizes with its mountainous environment while addressing waste management and resource efficiency for outdoor enthusiasts.
5 key facts about this project
01
Utilizes bamboo and clay for structural elements, enhancing sustainability.
02
Incorporates plastic-digesting fungi to manage waste on-site.
03
Features a modular design for easy transport and assembly in remote areas.
04
Employs a multi-layered roof membrane for optimized insulation and rainwater capture.
05
Integrates a frozen water filtration system for clean water access in cold climates.

### Project Overview
The Sponge House is designed for deployment in extreme mountainous environments, particularly in ecologically sensitive regions such as the Himalayas. The project aims to mitigate the environmental impact associated with increased human activity in these areas, focusing on waste reduction and resource conservation while providing a sustainable shelter for climbers and explorers.

### Environmental Responsibility and Innovation
The Sponge House incorporates several key features to enhance its environmental responsibility. It is equipped to generate its own power, and includes systems for waste processing, minimizing the ecological footprint on mountainous landscapes. The design employs locally sourced, low-impact materials such as bamboo and clay, and utilizes innovative components including multi-layered membranes for insulation and rainwater collection. Notably, it features plastic-digesting fungi, which provide a novel solution for converting non-biodegradable waste into consumable products.

### Modular Construction and Water Management
The design's modularity allows for efficient transportation and on-site assembly, utilizing a geodesic structure to ensure stability and energy efficiency. Integrated water management systems are designed to capture snowmelt and rainfall, employing methods such as frozen water filtration and transparent insulators to maximize freshwater resources. These features, combined with thermal performance enhancements, enable resilience in extreme weather conditions by strategically placing heat-generating elements and optimizing insulation.

### Materiality
The construction of the Sponge House employs a distinct selection of materials:
- **Bamboo**: Utilized for structural elements and insulation, valued for its lightweight and resilient properties.
- **Clay**: Sourced locally, providing non-toxic thermal mass and humidity control.
- **Multi-layered Roof Membrane**: Designed to capture and filter moisture and snow, it includes transparent insulation elements.
- **Plastic-Digesting Fungi**: This innovation is implemented to decompose plastics, addressing waste management.
- **Photovoltaic Systems**: Integrated for renewable energy generation to support the shelter’s electrical needs.

Through these strategies, the Sponge House emphasizes sustainability and adaptability, ensuring comfort and utility for its users while respecting the delicate alpine environment.

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.
