05
Energy production through underwater turbines reinforces the community's self-sufficiency.

### Project Overview

MicroPELAGO is situated on the ocean's surface and introduces floating micro-housing units designed to foster a sustainable lifestyle that interacts closely with marine ecosystems. The development comprises an interconnected network of microhomes anchored to three slender towers, emphasizing ecological responsibility and promoting community engagement within an aquatic context. Residents can adjust their living environments according to personal preferences through a core that allows rotational movement, enhancing privacy and interaction with nature.

### Material and Structural Strategy

The structural integrity and aesthetic appeal of MicroPELAGO are achieved through the innovative use of materials. Lightweight, monolithic 3D printed concrete serves as the primary construction material, minimizing waste while ensuring durability in harsh marine conditions. This is complemented by the use of bio-concrete enriched with volcanic ash to extend longevity. Transparent glass elements enhance interior brightness and foster a visual connection to the surrounding environment. Rainwater collection systems are integrated into the design, demonstrating a commitment to resource efficiency and sustainability.

The homes are organized around a central core that houses essential utilities and community spaces. This includes distinct sections for entry, living, kitchen, and sleeping areas, each designed to facilitate multifunctionality. The towers function as both structural elements and community hubs, capable of independent rotation to offer varied views and levels of privacy. Additionally, underwater turbines contribute to the energy needs of the development, supporting its off-grid capabilities while promoting a lifestyle harmonized with the oceanic environment.

### Community Integration and Biodiversity

MicroPELAGO extends its influence beyond the microhomes, incorporating platforms designed for communal use and direct interaction with marine life. These features facilitate a lifestyle closely aligned with nature, transitioning from conventional habitats to spaces that enhance biodiversity and support ecological resilience. The design focuses on fostering a vibrant community life while respecting and uplifting the surrounding ecosystem, positioning MicroPELAGO as a case study in sustainable architectural practice.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
