## Overview

Mutual House is an architectural design developed in Kent, United Kingdom, with a focus on sustainable living and community integration. This housing initiative serves the needs of a low-income couple while promoting a model for environmentally responsible construction. The design is informed by modern architectural practices and resource management techniques, emphasizing efficiency and ecological considerations in residential settings.

## Spatial Strategy and Functionality

The compact layout of Mutual House occupies 25 square meters, strategically designed to optimize space without sacrificing essential functionality. The configuration includes designated areas for the kitchen, dining/workspace, living room, bathroom, wardrobe, and bedroom. A central core houses vital services, thereby separating living areas and ensuring an efficient organization of space. This approach minimizes material use and construction costs while fostering an environment conducive to both living and working.

## Sustainable Material Use

The construction materials employed in Mutual House reflect a commitment to sustainability and resource efficiency. Key components include wooden cladding and structural elements, which not only provide thermal regulation but also create a natural aesthetic. The use of carbon fiber in the summer room structure enhances adaptability, while photovoltaic panels harness solar energy. Furthermore, recycled materials are utilized to reduce the construction's environmental impact. Notable features include an accordion-style carbon fiber room, which allows for flexible space adjustments based on seasonal needs or user requirements.

## Innovative Resource Management

Mutual House incorporates advanced systems for water and energy management. A rainwater collection system, supported by greywater recycling, aims to minimize freshwater use and manage runoff effectively. Additionally, a phytoremediation tank utilizes plant-based filtration to treat wastewater, integrating ecological practices into daily living. The energy system, featuring photovoltaic panels, allows for energy sharing among neighboring units, fostering a cooperative energy ecosystem that reduces reliance on external power sources and encourages sustainable community engagement.

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.
