Inflatable ETFE chambers within a double-curved concrete shell create a flexible open office space that encourages community interaction and expression at Jones Point Park.
5 key facts about this project
01
Inflatable ETFE chambers facilitate adaptable space usage.
02
The double-curved concrete shell enhances structural integrity.
03
Navigable channels connect multiple functional areas.
04
Designed to host celebrations and public expressions.
05
Located near the historic first boundary stone of the nation’s capital.

The project at Jones Point Park in Alexandria, United States, offers a modern take on historical significance while enhancing community engagement. Located at the site of the south boundary stone laid in 1791, the structure symbolizes the founding of the nation and its evolving identity. Designed to function as a temporary open office, it can host various activities, such as events for artists and festival organizers. This approach promotes a sense of flexibility and invites public interaction.

Design Concept

A continuous, flowing surface characterizes the design, integrating multiple functions into a cohesive whole. This form encourages interaction and highlights the need for adaptable public spaces. By avoiding conventional boundaries, the structure creates an inviting area that encourages visitors to explore and engage with their environment.

Spatial Organization

The structure features navigable channels and chambers, presenting a distinct spatial arrangement that accommodates diverse activities. These pathways create connections between indoor and outdoor areas, promoting various forms of public interaction. This layout enhances the building's functionality and fosters a sense of community among users.

Materiality and Construction

Concrete serves as the primary material for the shell of the building, offering durability and a contemporary appearance. Ethylene tetrafluoroethylene (ETFE) is employed in the chambers, providing a lightweight and flexible component that contributes to the overall adaptability of the design. Additionally, lightweight thread elements are used in the formwork of the double-curved shell, showcasing a construction method that mimics natural processes.

The design challenges traditional ideas of monumentality by focusing on openness and fluidity. It welcomes a variety of public expressions, such as celebrations and protests, reinforcing the ongoing narrative of liberty. This thoughtfulness culminates in a structure that is both responsive to its historical context and relevant to its contemporary purpose.

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.
