Rainwater Harvesting Through Funnel Architecture With Local Stone and Thermal Mass Utilization

Project in-detail

Harnessing rainwater through a distinctive funnel structure, the design incorporates local stone and thermal mass to create an efficient living space that emphasizes sustainability and resource management.
5 key facts about this project
01
Utilizes a funnel-shaped roof to efficiently capture and direct rainwater for storage.
02
Incorporates a natural filtration system using local soil and vegetation for wastewater treatment.
03
Constructed with thermal mass materials to enhance energy efficiency and temperature regulation.
04
Features extensive glazing to maximize natural light while maintaining privacy in living spaces.
05
Integrates native flora on the roof to promote biodiversity and improve insulation.
The Water Funnel House project exemplifies a contemporary architectural approach focused on sustainability and water management. Designed to respond to its mountainous geographic setting, this project employs innovative techniques in rainwater harvesting, aiming for a minimal ecological footprint. The architectural design merges both functional requirements and aesthetic considerations, resulting in a residence that promotes environmental stewardship.

The primary function of the Water Funnel House is to create a sustainable living environment that leverages natural resources for water management. A central feature of the design is the umbrella structure, which channels rainwater through its sloped surfaces into a filtration system. This system ensures the collection and reuse of rainwater, effectively addressing water scarcity concerns. The layout includes multiple living areas, integrating communal and private spaces while encouraging interaction among residents.

The architectural plans reflect a focus on open space and natural light, utilizing extensive glazing to connect indoor spaces with the surrounding landscape. The interior is organized into functional zones, including a central communal area, kitchen, bathroom, and bedrooms, effectively optimizing the use of space while maintaining comfort and livability.

Sustainability is at the core of this design. The project's water management system distinguishes it from typical residential architectures. The funnel structure not only serves a functional purpose but defines the aesthetic identity of the house. Materials chosen for the construction include concrete for structural integrity, glass for transparency, and locally sourced stone and soil for environmental harmony. These materials contribute to passive heating and cooling systems, reducing energy reliance.

The integration of green roofs with native vegetation enhances habitat biodiversity and thermal insulation, promoting energy efficiency. The project’s innovative approach to water management and sustainable resource use makes it a significant reference point for modern architectural practices.

To explore more about the Water Funnel House, including its architectural plans, sections, and detailed designs, readers are encouraged to review the comprehensive project presentation for deeper insights into its unique architectural ideas and functional elements.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
