Sustainable Habitat Integrating Bamboo and Biodegradable Fungi in Alpine Terrain

Project in-detail

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.
The Sponge House is an architectural design project conceived to address the challenges of human habitation in mountainous environments, such as the Himalayas. It aims to create a self-sufficient shelter that integrates seamlessly into the natural landscape while minimizing its ecological footprint. The project represents a departure from conventional alpine architecture, focusing on sustainability and resource efficiency in a demanding setting.

The primary function of the Sponge House is to serve as both a refuge for outdoor enthusiasts and a model for environmentally responsible construction. It is designed to support basic human needs—shelter and energy—while also emphasizing the importance of waste management and ecological awareness.

Efficient material use is a hallmark of this project. The structural elements are primarily constructed from bamboo, a renewable resource known for its durability and insulating properties. Clay is also utilized for its thermal mass and sustainability. The multi-layered roof membrane is engineered to optimize insulation and water collection, capturing snow melt and rainwater for reuse, further enhancing the building's self-sufficiency.

Unique Design Approaches
One of the distinguishing features of the Sponge House is its dual-purpose functionality. The design incorporates systems that not only provide a safe space but also actively engage in processing waste. Plastic-digesting fungi are integrated into the architectural framework, effectively addressing plastic waste and converting it into biodegradable materials. This bio-sustainability approach is a significant innovation that enhances the project’s environmental responsibility.

Adaptability is another key design aspect. The building employs a geodesic structure that ensures stability in harsh weather conditions while allowing for easy transport and assembly. Each module is designed to be lightweight and efficient, promoting lower carbon footprints during construction. Heat-generating components, such as a centralized wood stove, are strategically placed to maximize energy efficiency and comfort.

Sustainable Resource Management
The house's design emphasizes comprehensive water management. It features a frozen water filtration system that is capable of producing clean water by utilizing ice in winter months. Transparent insulating layers in the structure contribute to thermal performance, ensuring the interior remains habitable even in extreme cold.

The Sponge House challenges traditional notions of what it means to construct in remote areas, pushing the boundaries of architectural design by implementing innovative materials and sustainable technologies. The project serves as an important case study for future designs in similar environments, illustrating how architecture can provide human comfort while prioritizing ecological integrity.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
