With a compact footprint, this kiosk integrates a chemical toilet and sustainable energy systems within a modern design characterized by its glass walls and aluminum framework, providing a functional space for urban engagement.
5 key facts about this project
01
Compact design allows for easy placement in diverse urban environments.
02
Energy needs met by built-in photovoltaic panels and a backup generator.
03
User-centric features include a chemical toilet for extended operational periods.
04
Glass walls enhance visibility and interaction with the surrounding space.
05
Waste management system includes separate containers for efficient disposal.

The kiosk embodies a practical approach to enhancing user interaction in urban areas. Its dimensions of 365 cm in length and 270 cm in width allow it to fit comfortably into various settings. The design centers on a sturdy framework that integrates essential functions, creating a space that prioritizes accessibility and efficiency.

Structural Design

The structure relies on three aluminum pillars, which provide support and serve as key visual elements. Glass walls are used to maintain a sense of openness, allowing people to see inside while also adding to the integrity of the design. This transparency fosters a welcoming atmosphere, encouraging passersby to engage with the space.

User-Centric Features

An important aspect of the design is the inclusion of a bathroom that supports the needs of users. Designed as a chemical toilet, it is suitable for areas without sewer connections. This facility features a collection tank situated below the kiosk, optimizing space and ensuring easy access through a sliding door.

Material Choices

The materials chosen for the kiosk contribute significantly to its functional and aesthetic appeal. The external walls are made from steel sheet painted in soft brown and cream colors, creating a neutral backdrop. The floating wood floor adds warmth to the interior, enhancing comfort and maintaining simple upkeep. Insulation is provided by glass wool within the panels, offering fire resistance and soundproofing to create a pleasant environment inside.

Sustainable Elements

Sustainability is a key consideration throughout the design. Photovoltaic panels are included to generate energy, supported by a generator for periods of low sunlight. The heating and cooling systems are designed for efficiency, featuring a radiant panel for even heat distribution and a system to maintain airflow without increasing humidity. Integrated waste management features include three separate containers below the counter, promoting responsible disposal habits.

A hatch at the front, designed with hydropneumatic pistons, allows for easy closure when the kiosk is not in operation. The combination of user-focused design and thoughtful material selection results in a space that meets contemporary needs without compromising on functionality.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
