Gravitational Ventilation and Aluminum Cladding in a Traditional Herb Drying Barn

Project in-detail

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.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
