Harnessing Water Hyacinth Through Sustainable Polyethylene and Passive Solar Design

Project in-detail

Utilizing passive solar design and recycled materials, the facility transforms local water hyacinth into sustainable resources while serving as a collaborative workspace and educational hub for the community.
5 key facts about this project
01
Utilizes passive solar techniques to enhance energy efficiency.
02
Incorporates local craftsmanship through the use of regional timber.
03
Features dedicated harvesting facilities for managing water hyacinth.
04
Integrates educational pathways for community engagement and ecological awareness.
05
Employs recycled materials from existing structures for environmental sustainability.

The House of Water Hyacinth in Cardona, Rizal, Philippines represents an innovative approach to architecture that addresses both environmental and community challenges. This project is designed as a dual-purpose facility, serving not only as a workspace for local workers engaged in the harvesting of the invasive water hyacinth but also as a tourist attraction that educates visitors about ecological issues and sustainable practices. The architectural design emphasizes collaboration, education, and sustainability while providing functional spaces essential for productivity.

Functional Spaces and Layout

The House of Water Hyacinth features interconnected sections that promote interaction among users, creating a workplace conducive to teamwork and community engagement. The facility includes dedicated areas for harvesting and processing water hyacinth, ensuring that local workers have access to the necessary tools and resources. In addition, the layout incorporates visitor pathways that guide tourists through informative tours, effectively blending educational experiences with the working environment.

A key highlight of the design is the sun-drying infrastructure, which utilizes passive solar design principles to enhance energy efficiency. This feature not only supports the drying process of harvested materials but also minimizes energy consumption, reflecting the project's commitment to sustainability. Further, the use of glass in various elements optimizes natural lighting, fostering a bright and inviting atmosphere within the facility.

Sustainable Material Use

The project places significant emphasis on sustainable materials, which are integral to its design and functionality. Key materials include locally sourced wood, polyethylene, and glass. The incorporation of recycled materials from existing structures not only reduces waste but also connects the facility to the local context. The structural elements predominantly consist of wood, showcasing local craftsmanship while enhancing the aesthetic appeal of the architecture.

The architectural design prioritizes ecological awareness by incorporating features that highlight the interaction with the surrounding landscape. The site's planning integrates water management strategies, ensuring the ecological balance is maintained while providing functional outdoor spaces that support both work and tourism.

The House of Water Hyacinth stands apart from typical architectural projects by merging functionality with ecological responsibility. The integration of educational elements within the working environment fosters community involvement and raises awareness about local environmental challenges. This project advocates for sustainable practices while enriching the lives of local workers and visitors alike.

The Mujassam Watan Urban Sculpture Challenge invites architects and designers to create iconic public sculptures for one of two sites in Saudi Arabia: Abu Hadriyah Road or the Tharwa Sea Front in Al-Khobar. Proposals should reflect Saudi identity, culture, and future aspirations.

`

The Mujassam Watan Urban Sculpture Challenge is an international architecture and design competition inviting creatives to shape the future of Saudi Arabia’s public spaces. With a total prize fund of €50,000, the competition calls for sculptural proposals that merge cultural symbolism with innovative design, offering participants a chance to see their concepts brought to life in a rapidly transforming national context.

Organised by Buildner in partnership with the Mujassam Watan Initiative, the challenge focuses on two prominent locations: Abu Hadriyah Road, a major highway and gateway into the Eastern Province, and the Tharwa Sea Front in Al-Khobar, a pedestrian-focused waterfront district. Designers must select one site and develop a sculpture that engages with its surroundings—whether addressing the fast-paced dynamism of a transit corridor or creating moments of interaction along a coastal promenade.

Proposals should be bold, site-specific, and rooted in narrative—drawing on themes such as heritage, national identity, transformation, and dialogue. Environmental responsiveness, material durability, and feasibility are strongly encouraged, as winning projects may be selected for actual construction.

Each submission must include four A2 landscape presentation boards, a cover image, and a written project description. The competition is open to professionals and students alike, working individually or in teams of up to four people. No professional license is required.

Registration is open until July 24, 2025, with final submissions due by August 27, 2025. Winners will be announced on October 1, 2025.
