Equipped with photovoltaic panels and an innovative pivot mechanism, the design efficiently transitions between functions while integrating rainwater collection to support sustainable living for its occupants.
5 key facts about this project
01
The unit can pivot to transform its interior layout based on user needs.
02
It generates and stores electricity through fully integrated photovoltaic panels.
03
Rainwater is collected and stored in expandable bladders within the structure.
04
The design accommodates efficient gray water reuse for irrigation.
05
Modular transport allows for easy relocation by various means, including helicopter.

The Qube is a compact living unit designed for one or two people. It offers a self-sufficient lifestyle, focusing on essential needs such as cooking, sleeping, and bathing. The overall design features a cubic shape, which grants it functionality and adaptability. Its innovative approach allows for easy transportation, making it suitable for different settings, including urban and rural environments.

Modularity and Functionality

Inside, the Qube contains three main areas: a kitchen, a bedroom, and a bathroom. This layout encourages users to move between spaces easily by exiting the unit and flipping it over to access the desired room. A unique pivot mechanism uses gravity, winches, and external cables to facilitate this process. Such design creates a flexible living experience while maximizing the use of limited space.

Sustainability Initiatives

Sustainability is a guiding principle for the Qube. The unit generates and stores its electricity through photovoltaic panels. When the unit is oriented for sleeping, these panels are positioned to capture the most sun. The energy produced is stored in batteries, ensuring that lighting, cooking, and heating operates smoothly at all times. This self-sufficient energy system addresses common concerns about reliance on external power sources.

Water Management Solutions

Water is collected through a system that gathers rainwater on the roof and stores it in flexible bladders inside the unit. This design minimizes water loss, even when the Qube is moved. The unit includes a bathing basin, and gray water from everyday activities can be reused for irrigation in gardens shared among units. This approach promotes resource efficiency while enhancing the overall functionality of the living environment.

Community Living

The design of the Qube fosters a sense of community. In clusters, residents can utilize shared facilities like composting toilets, while smaller portable toilets are available for individual use. This arrangement encourages interaction among residents, balancing private living with communal aspects. The Qube supports both personal needs and a collaborative community, responding effectively to modern living challenges.

Elements like rainwater collection and expandable bladder systems illustrate a commitment to practical sustainability within an efficient compact form.

Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization.
