Dencity is an initiative addressing the urgent housing needs of urban residents in Paris. It focuses on creating adaptable living solutions by placing prefabricated housing units on existing rooftops. The design merges density with communal living, targeting young families, students, and migrants, all while promoting a modern urban lifestyle that encourages community engagement.

Design Concept

The emphasis is on creating modular units that residents can tailor to their specific needs. This flexibility addresses the varied requirements of city dwellers. By using prefabricated elements, the construction process is efficient, allowing for quick integration into existing structures. This approach maximizes limited space while maintaining a functional living environment.

Community Integration

The design prioritizes shared spaces and amenities to foster interactions among residents. Features like coworking spaces, coffee shops, and vegetable gardens are included to promote collaboration and community spirit. These elements not only enhance the living experience but also build connections among neighbors, helping to create a sense of belonging.

Site Selection and Urban Dynamics

Specific locations such as Rue Bouvier, Avenue René Coty, Rue des Partants, Rue Maillard, and Rue des Meaux have been chosen for their potential to support increased housing density. The design promotes both vertical and horizontal expansion, improving connectivity within neighborhoods. This careful site selection aims to offer necessary amenities while integrating new units into the existing urban landscape.

Material Specifications

Materials have been deliberately selected to achieve functional and sustainable outcomes. The foundation is made of concrete for stability. Steel forms the main frame, providing durability. Wood is used in the secondary structure, adding warmth to the spaces. Thermal insulation comes from fiberglass while acoustic insulation is provided by Prodex, enhancing comfort and reducing noise.

The design includes rooftop green spaces that connect with the surrounding environment, promoting biodiversity and a healthier urban lifestyle.

Vancouver Tall Challenge: Building Higher Downtown

`
Competition organisers

The Vancouver Tall Challenge: Building Higher Downtown is an international architecture competition organized by Buildner in collaboration with the City of Vancouver and the University of British Columbia’s School of Architecture and Landscape Architecture (SALA). The competition invites architects, designers, planners, and creative thinkers to explore innovative approaches to tall buildings in Vancouver’s downtown core, focusing on sustainability, livability, urban density, public space, and the city’s strong connection to nature. As Vancouver continues to grow, participants are challenged to rethink how vertical development can enhance urban life and contribute to a more vibrant, inclusive, and resilient city identity.

The competition offers a total prize fund of $15,000 CAD, with winning proposals selected by an international jury of architects, planners, academics, and city-building professionals. Key dates include the final registration deadline on October 29, 2026, submission deadline on November 30, 2026, and winners announcement on January 26, 2027.
