Buoyant Community Space Crafted from Concrete Ship and Porous Materials for Urban Resilience

Project in-detail

Crafted with buoyant concrete and integrated porous materials, the community space responds dynamically to urban flooding while fostering interaction among inhabitants through its multifunctional design.
5 key facts about this project
01
The structure operates on buoyancy principles, allowing it to adjust its position based on weight and water levels.
02
Utilizes porous concrete to facilitate natural water management, enhancing sustainability.
03
Incorporates a rainwater reservoir that contributes to its buoyancy and helps mitigate urban flooding.
04
Designed to foster community interaction through multipurpose spaces adaptable to various activities.
05
Integrates plant life within the architecture, creating a micro-ecosystem that promotes biodiversity.
The architectural project "Drowned in the Crowd" embodies a nuanced exploration of the interaction between built structures and environmental elements, particularly in urban settings susceptible to flooding. This design integrates the concept of “Moving Architecture,” illustrating how architecture can respond dynamically to both social and natural stimuli. By likening the structure to “Frozen Music,” the project establishes an imaginative framework where functional use is harmonized with the surrounding landscape.

At its core, this project functions as a versatile community space that addresses contemporary urban challenges by utilizing water as an integral element of both design and experience. The architecture promotes a relationship with nature, inviting users to engage with plant life and water features that contribute to the overall livability of the space. This adaptability is a central theme, where the architecture is not just a static object but a fluid entity that evolves according to the needs of its users, making it a unique addition to urban life.

The design encompasses several essential components, each playing a significant role in achieving the project's overarching goals. The Shell Hall serves as the main communal area, designed for a variety of activities, creating an inviting space for gatherings and events. The incorporation of stairs and the use of porous concrete further enhance functionality while promoting effective water management within the design framework. The structural strategy employed here allows for the collection of rainwater in a reservoir, which not only manages excess moisture but also aids in buoyancy, allowing the building to adjust to varying weight conditions.

A key aspect of the architecture is its duality between floating and sinking states, achieved through a careful balance of weight and design considerations. The project assumes a stable floating condition under normal usage but is engineered to accommodate increased loads effectively, ensuring continued safety and accessibility. This level of foresight in its design establishes a resilient framework that anticipates environmental challenges while providing a sustainable solution.

The materials selected for construction further contribute to the project’s distinctive character. The use of Concrete Ship signifies a commitment to durability and structural integrity, while porous concrete enables natural water flow through the space. Glass and steel are incorporated to provide visual transparency and enhanced connectivity between interior and exterior environments. This strategic choice of materials not only reflects the project’s identity but also underscores a focus on environmental sustainability and effective resource management.

Unique design approaches include the thoughtful integration of plant life within the architectural framework, fostering a micro-ecosystem that supports biodiversity. By creating spaces where nature coexists alongside human activity, the project emphasizes an important dialogue between the built environment and its natural context. This interaction transforms the overall experience, making the architecture a living entity that encourages ongoing engagement from its users.

The project's layout is meticulously planned to maximize both functionality and aesthetic appeal. Different zones are allocated for diverse activities, from communal gatherings to quieter reflection areas among greenery. Accessibility is prioritized, with well-designed pathways, trams, and stairs ensuring that individuals from various backgrounds engage with the architecture seamlessly.

The innovative nature of "Drowned in the Crowd" represents a concerted effort to rethink traditional architectural paradigms. By placing emphasis on adaptability, sustainability, and community interaction, the project serves as a model for future architectural endeavors that aim to tackle pressing urban issues. To delve deeper into the nuances of the design, including architectural plans and sections, prospective readers are encouraged to explore the project presentation for a comprehensive understanding of its intricacies and inspirations. This exploration can provide valuable insights into how architecture can indeed shape environments and foster community connections in a changing world.

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.
