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.

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.
