Incorporating gravitational ventilation and aluminum cladding, the herb drying facility revitalizes a historic barn structure while maintaining its agricultural roots and promoting sustainable practices.
5 key facts about this project
01
Retains original north-south oriented barn walls for structural integrity.
02
Employs gravitational ventilation to optimize air flow without mechanical systems.
03
Integrates windcatching techniques to enhance natural cooling.
04
Utilizes aluminum cladding for durability and modern aesthetics.
05
Encourages community involvement through incremental construction methods.

The design focuses on adapting a historic barn structure for modern agricultural use. Located in an area with deep agricultural roots, the facility is primarily intended for drying herbs. By combining the old walls with new features, the design respects the heritage of the site while also addressing contemporary needs related to agriculture. It aims to promote sustainability and efficiency while fostering community use through a deliberate and organized layout.

Structural Integrity

Retaining the north-south oriented walls of the original barn is central to the design. These walls provide essential support while preserving the historical context of the structure. The thoughtful organization of the space allows for easy movement between different functional areas, including drying storage, workshops, living spaces, and mechanical rooms. This design encourages interaction among the various sections, making the building a multifunctional agricultural facility that is both practical and efficient.

Ventilation Strategies

Effective ventilation is key to the herb drying process. The design includes two main natural ventilation methods. Gravitational ventilation relies on the heat from the external surfaces of the building, which causes air to rise and creates a cycle of air exchange without the need for mechanical systems. Additionally, windcatching is integrated into the design, drawing in fresh air while pushing out stale air. These methods work together to create an environment suitable for drying herbs while reducing energy consumption.

Material Selection

Careful choices in materials play a significant role in the overall design. Aluminum cladding has been chosen for the exterior of the new structure. This durable material supports the gravitational ventilation system and aligns with the project’s sustainability goals. The aluminum provides a modern look that complements the texture of the existing stone walls, creating a visual balance between the old and the new elements of the structure.

The design combines traditional agricultural practices with modern techniques, ensuring the facility is both useful and respectful of its history. This balance is highlighted by the simplicity of its form, allowing natural light to interact with the drying spaces, enhancing their functionality and character.

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. Full competition details, requirements, and registration information are available at architecturecompetitions.com/VancouverTallChallenge
