Cross-Laminated Timber forms the structural backbone of a new urban community in Saint-Denis, where innovative designs promote biodiversity through integrated farming and shared spaces, providing sustainable housing for diverse residents.
5 key facts about this project
01
Mid-rise apartment units feature a single corridor design for enhanced spatial efficiency.
02
The development includes designated areas for keeping goats and chickens for urban agriculture.
03
Rooftop community gardens provide sustainable food sources and recreational spaces.
04
Cross-Laminated Timber construction enables both structural strength and carbon capture.
05
Zoning regulations support low energy use and biodiversity through integrated features.

The design focuses on housing solutions in Saint-Denis, located in the northern suburbs of Paris. This area, known for its rich history, has been the backdrop of significant social movements. The project includes mid-rise apartment units and double houses. The overall aim is to create spaces that enhance community life while promoting sustainability.

Mid-Rise Apartment Units

Mid-rise apartment units offer a fresh perspective on how to use space in residential design. They feature a single corridor for every two floors, which permits larger living spaces. This thoughtful arrangement provides both functionality and comfort for residents. High ceilings in the main living areas help create an open atmosphere. Bedrooms are designed with windows on opposite walls, allowing for better ventilation and reducing the need for artificial cooling.

Accessibility is also a key feature in the design. There are wheelchair-friendly apartments alongside two-story layouts that meet diverse needs. Shared spaces for keeping goats, pigs, and sheep integrate urban agriculture into daily life. A rooftop community garden offers not just a place for plants but a space for residents to interact and learn about sustainable practices.

Double House Proposal

The double house design tackles zoning challenges by allowing a higher density without compromising individual living standards. It aims to maximize available space while fostering a sense of community among families. This design integrates both living and working spaces, giving residents the chance to blend personal and communal activities seamlessly.

Zoning regulations support low energy consumption and promote strategies for carbon capture. The development permits urban farming, including rules for raising backyard animals like goats, rabbits, and chickens. This relationship with nature reflects a growing commitment to responsible land use and biodiversity in urban environments.

Materials and Environmental Features

Material choices are an essential part of this design and provide foundational support. Cross-Laminated Timber (CLT) and heavy timber are the preferred options. These materials not only ensure structural strength but also help capture carbon.

Additional features like bat houses and dovecotes contribute to the ecological richness of the area, creating habitats that bolster local wildlife. Renewable energy options, including heat pumps and photovoltaic solar panels, are strategically placed to enhance energy efficiency throughout the site.

Private gardens for each apartment connect residents to the environment, enriching their living experience and fostering a sense of responsibility for local ecology.

`
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.
