## Project Overview

The Piazza Galeno project is situated along Regina Margherita Avenue in Rome, Italy, an area characterized by significant vehicular traffic and urban congestion. The intent is to convert this traditionally vehicle-oriented square into a pedestrian-centric space that fosters social interaction and community engagement. This design integrates green spaces and pocket parks around the square, forming a conducive environment for community activities and enhancing urban livability.

## Spatial Organization and Connectivity

The layout consists of a primary multipurpose hall complemented by auxiliary spaces that facilitate circulation and user interactions. Elevated above the ground plane, the hall offers clear sight lines across the area, while the design strategically separates pedestrian pathways from vehicular routes, ensuring a secure zone for cultural and community events. Pathway diversity promotes accessibility and encourages natural movement through the square, effectively delineating areas for various functions.

## Materiality and Structural Features

Material selection reflects both functional needs and aesthetic objectives. Key materials include highly reflective concrete for the pavilion, eroded concrete surfaces for tactile quality, and light-transmitting concrete that allows natural light to penetrate the structure. Colour-pigmented concrete is utilized to define pathways, while durable concrete paving facilitates social interaction within pedestrian areas. Structural elements feature a lightweight concrete envelope for the hall, coupled with an intricate roof design that enhances both natural light and ventilation, thus contributing to the overall atmosphere and sustainability of the space.

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.
