Housed within a repurposed railway arch, the design utilizes a timber frame structure and adaptable acoustic panels to create a versatile workspace that promotes social interaction and sustainability.
5 key facts about this project
01
The project is located in an abandoned railway arch, integrating historical context into its design.
02
The structure utilizes an innovative timber frame system that enhances adaptability.
03
Acoustic panels allow for flexible spatial arrangements based on user needs.
04
Natural light is strategically distributed using reflective light pipes throughout the interior.
05
The design incorporates elements that promote eco-friendly transportation, such as bike racks and lockers.

Puzzle Works is located in an abandoned railway arch in London and serves as a versatile workspace that balances collaboration with individual focus. The design embraces a modern approach, emphasizing adaptability and functionality. It draws inspiration from a sliding puzzle, showcasing how spaces can be organized, combined, and divided to meet users' needs.

Central Gathering Space

The design features a communal dining area situated beneath a large void, creating a central hub for social interaction. This gathering point encourages both cooperation and community among users. Next to the dining space, there is a library found under the stairs, providing a quiet spot for meetings and reflection. Integrated lockers and bike racks support eco-friendly transportation choices, reinforcing a commitment to sustainability in everyday practices.

Dynamic Panel System

A standout feature is the communal dining table, which interacts with the overhead panel system. This table can change from a large surface into smaller sections for various events. The acoustic partition panels are electronically controlled, allowing users to adjust them vertically and horizontally. This flexibility helps redefine spaces as needed, creating an environment that adapts to the changing nature of modern work.

Sustainability and Natural Ventilation

The project focuses on meeting sustainability goals through retrofitting existing structures and offering a modular design that encourages movement and interaction. Alcoves located between structural columns serve multiple functions, promoting a sense of connection throughout the workspace. Natural ventilation is achieved through well-placed windows that work alongside an integrated HVAC system. Acoustic baffles in open areas improve sound quality, enhancing comfort during collaborative work.

Light and Visibility

Half of the level was excavated, making it possible to see communal activities from the outside while maintaining privacy for the upper levels. The design includes a daylighting strategy that uses reflective light pipes to distribute natural light throughout the space. This approach minimizes the use of artificial lighting and creates a warm atmosphere. Puzzle Works skillfully balances light and space, enhancing the overall experience for users while promoting a sustainable and engaging work environment. The thoughtful interplay of these elements defines the unique character of the space, offering functional solutions for everyday use.

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.
