### Concept Overview
Located in a coastal environment, The LightHouse addresses the pressing issues of rising sea levels and urban density through the design of a microhome that promotes sustainability and functionality. The structure aims to provide residents with a lifestyle that is both practical and reflective of its aquatic surroundings. It is conceived as an adaptable living space that fosters a connection between the occupants and the natural landscape.

### Spatial Organization
The LightHouse features a two-level layout designed to facilitate indoor and outdoor interactions effectively. The ground floor encompasses approximately 16.43 square meters and includes communal areas such as a kitchen, living space, and storage solutions. The design emphasizes versatility, allowing for social gatherings and functional use of space. The upper level comprises a private bedroom, measuring 8.29 square meters, which benefits from extensive glazing, offering expansive views of the surrounding water and landscape.

Key elements of the spatial layout include:
- **Kitchen and Living Area**: The kitchen is strategically designed to encourage communal cooking experiences, while the living area offers flexible seating arrangements conducive to gatherings.
- **Private Bedroom**: This upper-level space prioritizes comfort and tranquility, with operable deck features that enhance the user experience and enable unobstructed engagement with the views.

### Materiality and Environmental Considerations
The construction of The LightHouse employs materials selected for their sustainability and resilience in marine contexts. Notable materials include:
- **Molded Shells (Prefabricated Off-Site)**: This structural key component supports efficient transport and installation while ensuring stability in coastal conditions.
- **Recycled Boat Fiber Reinforced Plastic**: Utilized for durability, it incorporates recycled elements to minimize environmental impact.
- **Solar Panels (25 kW)**: Installed for energy production, these panels support a hydrogen electrolyzer that contributes to sustainable energy use.
- **Detachable Floating Modules**: Designed to accommodate variable user needs, these modules enhance the adaptability of the home.
- **Water Harvesting Systems**: Integrated technology for rainwater collection ensures responsible water management practices.

Through these materials, The LightHouse serves as a model for resource conservation and energy efficiency, fostering an environmentally conscious approach to living.

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.
