Photovoltaic Glass and Hydroponics in a Sustainable Riverbank Shelter

Project in-detail

The integration of photovoltaic glass with hydroponic cultivation modules creates a sustainable habitat that enhances agricultural productivity along the riverbanks of northern Chile.
5 key facts about this project
01
Hydroponic modules optimize food production with minimal land use.
02
Concentric ring design enhances fluid movement and interaction.
03
Azuda wheel system efficiently generates renewable energy.
04
Photovoltaic glass integrates solar power directly into the structure.
05
Laboratory space focuses on research of local greenhouse practices.

The Water Mill Shelter integrates living spaces and agriculture along the rivers of northern Chile. Designed around the concept of utilizing hydraulic energy through the azuda wheel, it focuses on sustainability by harnessing water and solar energy. The design reflects a commitment to creating a harmonious relationship between human habitation and the natural environment.

Design Strategy and Functionality

The structure features a series of concentric rings that create distinct areas for living and working, including a laboratory for agricultural research. This layout encourages natural movement throughout the space, allowing for efficient workflows and interactions. Agronomists can easily transition between various tasks, enhancing the productivity of their work studying local greenhouse practices.

Mechanical Integration

Key mechanical systems enhance the shelter’s energy efficiency. Elements like water tanks, floatators, and a water mill collectively generate sustainable energy. These systems not only fulfill the basic energy needs but also illustrate the potential for architecture to coexist meaningfully with natural resources.

Sustainable Practices

Hydroponic cultivation modules are a prominent feature of the shelter, allowing for effective food production with minimal land usage. This aligns with modern perspectives on urban agriculture and the necessity for sustainable food systems. The modular design allows the shelter to be set up strategically along riverbanks, taking advantage of available water resources while limiting environmental impact.

Material Considerations

Material choices in the project emphasize both sustainability and durability. Photovoltaic glass captures solar energy, while structural components like wood beams ensure robustness. These materials enhance the shelter's connection to the environment, supporting its ecological goals while maintaining an appealing aesthetic.

Design elements such as retractable windows open the interior spaces to the outdoors. This design detail encourages interaction with the natural surroundings and emphasizes the project’s focus on environmental integration.

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.
