Spiral Design Incorporating Hydroponics and Green Roofs in Reinforced Concrete Structure

Project in-detail

A spiraling structure with integrated hydroponics and green roofs allows for an innovative approach to urban agriculture, creating a multifunctional space that fosters community engagement and sustainable living.
5 key facts about this project
01
Spiraling pathways connect multiple levels, enhancing user circulation and accessibility.
02
Integrated hydroponic systems support year-round urban farming capabilities.
03
Green roofs mitigate stormwater runoff while promoting biodiversity.
04
Reinforced concrete and glass facades optimize energy efficiency and natural lighting.
05
Community gathering spaces are designed to facilitate social interactions and events.

The project "The SPIRAL" is an architectural initiative located in the Royal Docks area of London, UK. It functions as a mixed-use facility that integrates urban farming within an innovative architectural framework. The design concept features a spiraling structure that enhances user circulation and fosters community engagement. The project emphasizes sustainability through its incorporation of green technologies and adaptive reuse of space.

This architectural endeavor represents a response to the growing need for urban agriculture solutions in metropolitan environments. The SPIRAL not only serves as a hub for food production but also as a community space that encourages social interaction and educational opportunities related to sustainable practices.

Innovative Design Approaches

One of the distinctive features of The SPIRAL is its "Horizontal Vertical Farm" concept, which merges traditional farming techniques with modern architectural design. This approach allows for the integration of agricultural production areas within the built environment. Hydroponic systems are strategically placed throughout the facility to maximize space efficiency and yield. The spiral design facilitates easy access to different agricultural zones while creating a visually cohesive flow of movement.

The architectural layout includes designated zones for farming, community engagement, and commercial activities. Public gathering spaces within the design are equipped with seating and landscaping that promote outdoor interaction. This blend of functions is carefully articulated to promote accessibility, making spaces available for both private and public use.

Sustainability and Materiality

The SPIRAL prioritizes sustainability through the use of eco-friendly materials and systems. Key materials include reinforced concrete, glass facades, and steel frames, chosen for their structural integrity and energy efficiency. Photovoltaic panels are integrated into the design to harness solar energy, contributing to the building's net-zero energy goals. Green roofs and vertical gardens enhance biodiversity and assist in stormwater management.

This emphasis on ecological design aligns with the project’s mission of responding to urban challenges, such as food security and environmental sustainability. The integration of green spaces within the building encourages a connection with nature and supports local flora and fauna.

The SPIRAL exemplifies a pragmatic approach to contemporary architectural design. For more detailed insights into its architectural plans, architectural sections, and architectural designs, interested readers are encouraged to explore the full project presentation. This resource will provide a comprehensive understanding of the architectural ideas that drive The SPIRAL’s innovative design and functionality.

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.
