In an industry defined by building codes, climate urgency, and the pressures of the real estate market, the architectural competition has quietly become one of the discipline's most generative spaces. Unburdened by budgets, clients, or city regulations, competition entries allow architects to think at the edge of what the built environment could be, and increasingly, that speculative work is being taken seriously as a cultural and intellectual contribution in its own right. Buildner's Unbuilt Award, now in its second edition, is one of those efforts, by treating the unbuilt project as a platform for architects and designers to share concepts that challenge boundaries and inspire future possibilities. In this way, competitions like this allow architecture professionals and students to showcase ideas and visions that, even without being constructed, reflect the spirit of exploration and ingenuity in architecture.
Buildner has also announced the results of Buildner's Unbuilt Award 2025, the second competition in a series celebrating architectural design that has yet to be realized. With a generous 100,000 EUR prize fund, this initiative provides a global platform for architects and designers to showcase their most compelling unbuilt projects, whether conceptual, published, unpublished, or fully developed.
Across geographies and generations, architects are rethinking the idea of home, balancing personal expression, contextual sensitivity, and material clarity. These contemporary residential proposals, submitted by the ArchDaily community, reveal how the house continues to evolve as both an architectural statement and an intimate landscape for living. From the sculptural and futuristic to the grounded and vernacular, they explore how built form balances between identity, environment, and lifestyle in an increasingly complex world.
Amid questions, reflections, and debates, the work of Clorindo Testa embodies an innate connection between artistic and architectural experimentation, reflected in many of his built projects, sketches, models, and plans. From the Mariano Moreno National Library to the former Bank of London building in Buenos Aires, his production is of such scope, diversity, and complexity that it constitutes a major source of study, one that also includes unbuilt projects that deserve visibility and recognition on a global scale. In his final years of professional activity, two unbuilt projects of religious architecture highlight Testa’s work not only as an architect but also as a visual artist.
The use of primary colors, pure forms, and concrete represent some of the most distinctive characteristics of Clorindo Testa’s architecture, which is inseparable from his visual art. Reflecting on themes such as living in large cities or the conditions of life in urban spaces, the powerful expressiveness and plasticity of his works, together with the character of the line, his typical color palette, and the frequent presence of the human figure, reveal the importance and meaning he attributed to scales, uses, and perceptions as an architect who never settled for the first idea.
In today's architectural discourse, masterplanning is increasingly recognized as a means to reconcile growth with long-term social, cultural, and environmental priorities. Beyond organizing buildings and infrastructure, these large-scale proposals aim to regenerate urban fabrics, adapt historic or underutilized sites, and establish frameworks for inclusive and resilient communities. Submitted by the ArchDaily community, the projects featured in this edition of Unbuilt Architecture highlight how masterplans can respond to contemporary challenges while preparing cities for an uncertain future.
Spanning diverse geographies, from Europe to the Middle East and the Americas, the selected projects reinterpret industrial complexes, cultural sites, and residential neighborhoods through strategies that prioritize sustainability, mobility, and collective identity. Many share a focus on regenerative design: reopening historic canals, creating climate-adapted public spaces, and introducing green corridors and community hubs to reconnect people with their environments. Together, they showcase how masterplanning is evolving into a critical tool for rethinking how cities grow, adapt, and sustain civic life.

In the contemporary context, museums face contradictory sets of ideas: becoming attractions on and of themselves but presenting an understated image that shifts the attention to the exhibits, creating a safe and protected environment for the artifacts, yet opening them up to the public, becoming repositories of history yet catalysts for innovation. Searching for the balance between all of these constraints has resulted in the flourishing of diverse types of museums and cultural institutions, from those dedicated to the remembrance of a single event or persona to temporary homes for cultural events or spaces that expand their cultural offering beyond exhibition areas.
This curated selection of Best Unbuilt Architecture highlights projects submitted by the ArchDaily community that demonstrate the fusion of art, technology, and innovation within the realm of museums and cultural centers. Among the featured designs are works from renowned architectural offices, including CAA architects, NextOffice – Alireza Taghaboni, and Fentress Architects, along with several emerging firms. Ranging from a sculptural art museum in Dubai to a local cultural and recreational complex in Senegal, or an immersive science museum in Rome, Italy, this diverse compilation strives to showcase the spectrum of scales and purposes of cultural institutions.
