Leveraging the overground railway network, this development employs modular construction to create high-density co-living units that offer affordable housing solutions in a dense urban landscape.
5 key facts about this project
01
Modular units can be easily reconfigured based on resident needs.
02
Utilizes existing railway infrastructure to minimize land use impact.
03
High-density living is designed to foster community interaction.
04
Construction methods focus on carbon-negative solutions.
05
Direct access to public transport enhances urban connectivity.

The design focuses on addressing the urgent need for affordable housing in London, utilizing the city's extensive overground railway network. With land prices reaching £93.3 million per hectare, the initiative proposes to create residential units that do not expand the city’s footprint. By taking advantage of over 1,100 kilometers of uncovered railway tracks, the aim is to build decks that could accommodate around 250,000 homes, responding to the significant demand for housing in urban areas.

Modular Approach

A modular housing system, referred to as ON BOARD, forms the foundation of the design. This system allows for customization and adaptability, enabling residents to adjust unit layouts according to their individual needs. High-density co-living units feature shared kitchens and communal spaces, promoting a supportive community environment. Such configurations encourage social interaction among residents and cultivate a sense of belonging.

Sustainability Considerations

The design places a strong emphasis on environmentally sustainable construction methods. Although specific materials are not mentioned, the focus is on carbon-negative solutions that reduce the environmental impact of buildings. Prioritizing low-impact materials aligns with current practices aimed at achieving energy efficiency and sustainability in urban settings.

Community Engagement

Creating spaces for communal activities is integral to the overall design. By incorporating shared areas, the layout encourages interactions among residents, fostering a collaborative atmosphere. This design philosophy combines private living and communal spaces, enriching the everyday experience of urban living.

The architectural plan culminates in a thoughtful arrangement that enhances accessibility and promotes connections among residents. Communal spaces are designed for gatherings and shared experiences, contributing to a vibrant community spirit within the urban context.

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.
