Subterranean Structure Embracing Corten Steel and Concrete with Integrated Hydroponics

Project in-detail

Constructed with Corten steel and concrete, this subterranean car barn integrates hydroponic farming and versatile spaces to serve as a practical storage facility while promoting sustainability within its natural landscape.
5 key facts about this project
01
Constructed partly underground to minimize visual impact and enhance landscape integration.
02
Incorporates hydroponic farming to promote sustainable urban agriculture within the facility.
03
Features Corten steel cladding that develops a unique patina over time, enhancing durability.
04
Includes multifunctional spaces to serve community needs beyond vehicle storage.
05
Utilizes passive design principles to optimize natural light and thermal efficiency.

The Subterranean Car Barn is an innovative architectural project that exemplifies effective integration of function, sustainability, and aesthetics within a natural landscape. This architecture serves a dual purpose: it functions primarily as a storage space for vehicles while also providing additional multipurpose areas that cater to various community needs. The structure is partially embedded into the landscape, minimizing its visual footprint and allowing for a greater connection with the surrounding environment.

One of the key aspects of the design is the careful selection and combination of materials. The building uses concrete for its structural elements, ensuring durability and longevity. Corten steel is utilized for exterior cladding, which not only presents an industrial aesthetic but also engages in a weathering process that lends character to the structure over time. Wooden features are included to soften the overall appearance and enhance the building's relationship with the natural surroundings, promoting a sense of warmth and approachability. Large glass windows enable natural light to permeate the interiors, contributing to an inviting atmosphere.

The project showcases several unique design approaches that distinguish it from conventional car storage facilities. The subterranean aspect of the building allows it to harmonize with the terrain, reducing environmental impact while also preserving the topography of the site. The layout emphasizes flow and connectivity, with spaces dedicated to both utility and leisure that can be utilized for various community activities. Integrating an indoor hydroponic farm further supports sustainable practices, allowing occupants to engage in urban agriculture right within the premise.

The design also emphasizes multifunctionality. Apart from vehicle storage, the Car Barn offers space for a kitchen, offices, and a communal area, reflecting a versatile use of space that invites community interaction. This focus on adaptability ensures that the building can serve not only as a practical solution for vehicle storage but also as a resource for local initiatives and gatherings.

For further insights into this project, including architectural plans, sections, and design ideas, readers are encouraged to explore the detailed presentation of the Subterranean Car Barn. This will provide a comprehensive understanding of its innovative architectural approach and functional design.

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.
