## Overview

The design proposal for the Rome Concrete Poetry Hall presents a cultural venue aimed at enhancing the urban experience in Rome, strategically located at a key transport hub. The project integrates elements of Roman heritage while exploring contemporary architectural expressions, with a focus on themes of concrete, poetry, and spatial interaction. The design is informed by notable Roman landmarks, including the Pantheon and the Colosseum, and utilizes the motif of the sphere to represent diverse experiences and the unique interplay of light.

## Spatial Configuration

The proposal features a multi-level structure that includes a significant underground space known as the “Sphere Void.” This volume connects various areas within the hall, promoting movement and social interaction. Concentric circular arrangements facilitate a dynamic flow, culminating in the inclusion of exhibition areas and cafés that are designed to engage with the public. A fountain at the lowest level serves as a contemplative focal point, enhancing the reflective quality of the environment.

## Materiality and Structural Composition

Concrete is the primary material used in this proposal, selected for its strength and versatility in shaping innovative architectural forms. The design allows for the creation of complex geometric shapes, embodied in the proposed double spiral structure that reflects modern architectural capabilities. Glass elements are incorporated to enhance natural light penetration throughout the interior, contributing to an inviting atmosphere. The façade and interior finishes are further developed to complement the overall sensory experience within the hall.

The design additionally incorporates a landscaped ‘hill’ to obscure underlying transport infrastructure, promoting a pedestrian-friendly plaza that fosters public accessibility and engagement, in line with contemporary urban design principles.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
