Stepped Greenhouse Incorporating ETFE and Natural Ventilation for Community Engagement

Project in-detail

Utilizing a stepped form and a façade of ETFE, the design integrates natural ventilation and hydroponics to create a sustainable community space that fosters agricultural practices and social interaction.
5 key facts about this project
01
Stepped design aligns with natural terrain to optimize sunlight and drainage.
02
ETFE façade allows for natural light while enhancing thermal performance.
03
Integrated hydroponics support sustainable agriculture and education.
04
Community spaces feature flexible layouts for diverse functional uses.
05
Water gardens enhance biodiversity and improve site ecology.
The architectural design project features a stepped greenhouse and multipurpose space, located within an undulating landscape that enhances its function and aesthetic. The design effectively incorporates natural contours to create spaces that serve both agricultural and community purposes. Encompassing sustainability and innovation, the project aims to foster ecological relationships while ensuring accessibility for users.

The central structure of the project comprises a stepped greenhouse that optimizes sunlight exposure and internal environmental conditions. This greenhouse utilizes advanced materials like Ethylene Tetrafluoroethylene (ETFE) for its transparent façade, facilitating natural light while minimizing heat loss. The hydroponic systems integrated into the greenhouse allow for efficient cultivation of plants, making it a model for sustainable agricultural practices.

The multipurpose space adjacent to the greenhouse encourages community engagement through its flexible design. This area is intended for gatherings, workshops, and other social interactions, focusing on adaptability in its layout. Well-designed entry points connect the multipurpose space to the surrounding landscape, promoting ease of access and movement.

The project's unique approach lies in its responsive design to topography, which distinguishes it from typical structures. The stepping elements not only enhance the visual appeal but also contribute to functional aspects, allowing users to navigate the site easily. Additionally, the incorporation of water gardens creates natural reservoirs that enhance biodiversity and support the overall ecological framework of the development.

The use of materials such as aluminum plates for structural components and concrete for foundational elements reinforces the durability and longevity of the design. The warm aesthetic of wooden decking adds to the inviting nature of the interiors, thereby balancing practicality with visual comfort.

Exploring the architectural designs and visual representations of this project can provide deeper insights into its planning and execution. Review the architectural plans, sections, and unique ideas that characterize this innovative design approach to gain a comprehensive understanding of its scope and impact.
