The integration of rotatable modules and bioconcrete in this living space optimizes energy efficiency and promotes sustainability while providing a flexible environment for residents.
5 key facts about this project
01
Rotatable modules allow for customized interior layouts based on sunlight exposure.
02
Bioconcrete enhances air quality by supporting plant growth on vertical surfaces.
03
Energy is generated through a combined use of solar panels and wind turbines.
04
The design accommodates both solid ground and water, offering versatile placement options.
05
Integrated bioreactors convert algae into biogas for renewable energy supply.

The design features a multifunctional living space focused on adaptability and energy efficiency. Located in a setting that accommodates both solid ground and water, the building consists of three rotatable modules. These modules allow residents to tailor their living environment based on their needs. The overall concept centers around the idea of sustainability, making use of innovative energy strategies while providing a flexible and dynamic interior.

Energy Generation

The building incorporates solar modules on the roof. These can be adjusted to capture sunlight effectively throughout the day. In addition, the modules can function as rotor blades, utilizing wind to generate energy through a central generator. This combination of solar and wind energy reflects a strong commitment to sustainable living practices.

Bioreactor Facade

Vertical elements of the facade feature surfaces designed for bioreactors, where algae can thrive. Using solar energy, these algae produce biomass that is converted into biogas. This biogas fulfills some of the building's energy requirements through a fuel cell. This aspect of the design emphasizes the integration of biological processes, contributing significantly to the building's energy sustainability.

Technical Infrastructure

At the core of the building is a technical room, which houses essential components for energy storage, including batteries, a generator, and a fuel cell. This centralized arrangement helps manage the energy produced by the building efficiently, ensuring that it powers both living spaces and water heating systems. This infrastructure promotes a responsive and effective energy management system.

The choice of bioconcrete as the primary structural material supports plant growth. The design encourages the growth of moss, lichen, and mushrooms, all of which improve air quality and insulation. The use of wood in other parts of the structure complements these efforts, highlighting a focus on sustainability and a connection to nature in the overall design.

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.
