Water Harvesting Systems With Filament Winding Fabrication in Sustainable Housing

Project in-detail

Utilizing filament winding fabrication for lightweight components, the design incorporates comprehensive water harvesting systems to create sustainable housing in urban contexts.
5 key facts about this project
01
Filament winding fabrication allows for lightweight and strong structural components.
02
Integrated water harvesting systems support sustainable domestic water use.
03
Internal cavities facilitate gray water treatment based on wetland principles.
04
Thermal mass is achieved using stored rainwater for energy efficiency.
05
Design emphasizes direct interaction with local water cycles.

The Home Spun project addresses the needs of shrinking cities, particularly those within the Great Lakes region. It seeks to redefine urban housing by connecting sustainable practices with systems for managing water. The design aims to create a community that emphasizes the importance of ecological health while engaging with nearby water sources. By encouraging interaction with natural water cycles, residents are invited to reconsider their relationship with this vital resource.

Design Concept and Spatial Configuration

The architectural framework of Home Spun reconsiders how living spaces relate to water systems. The design centers on making the water containment system a prominent feature, shifting away from conventional plumbing as an afterthought. This layout creates a direct connection between residents and their environment, allowing for meaningful engagement with the local ecology. It is particularly designed to enhance density and efficiency in neighborhoods affected by population loss and urban decline.

Construction Techniques

Filament and tape winding fabrication techniques are utilized, resulting in lightweight prefabricated components. This construction method optimizes the use of existing manufacturing resources and minimizes energy use during production and transportation. The reduced weight of these components allows for easier installation while supporting the overall sustainability of the housing units.

Water Harvesting and Management

Home Spun’s design includes effective water harvesting systems. It captures rainwater and melting snow, storing it within structural columns that fulfill multiple roles. Internal cavities direct the collected water from the roof to a holding tank, and an integrated living machine processes gray water using principles drawn from wetlands. This approach to water management supports sustainability and invites residents to participate in eco-friendly living.

Thermal Efficiency

To counter the challenges of lightweight construction, Home Spun integrates harvested water for thermal mass. The walls and columns are designed to help maintain indoor temperatures while serving domestic water needs. Additional features, such as a geothermal heat pump and a communal reserve water heater, create a comprehensive strategy for managing heating and cooling, ensuring comfort in the residential spaces.

The design exemplifies a thoughtful balance between living and environmental needs. By combining effective water management with innovative construction, it generates a space that responds to the realities of urban living.

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.
