The London Affordable House addresses the urgent need for affordable housing in an urban environment. It is situated in London and focuses on creating a functional living space while promoting sustainable practices. The design consists of two overlapping square forms that create an interesting building profile. This approach not only maximizes usable space internally but also integrates well with the urban context.

Materiality and Sustainability

Wood is the main material used for construction, chosen for its cost-effectiveness and environmental benefits. Compared to concrete, wood lowers construction costs and reduces the overall carbon footprint. It is a renewable resource that contributes positively to energy efficiency within the home. The use of wood provides warmth and character to the interior while supporting a sustainable approach to home building.

Spatial Organization

The intersecting forms generate diverse spatial arrangements that allow for flexible living. Areas within the house cater to both communal and private needs, ensuring comfort and functionality. The layout thoughtfully considers how space is used, promoting interaction while allowing for solitude. The southern orientation plays a key role in enhancing natural light within the home, improving the quality of each space.

Interior Ambiance

Natural light is a critical factor in creating a welcoming atmosphere throughout the house. By strategically positioning the home to face the south, it captures sunlight effectively, leading to bright and airy rooms. This design choice supports a pleasant living environment, enhancing daily life for residents.

The design language is simple and modern, with a focus on clean lines and geometric forms. Each form interacts with the other in a way that highlights the relationship between space and structure. Areas are defined yet connected, balancing the need for openness and privacy.

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.
