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.

Public spaces are the beating heart of our cities. They act as the hubs of social and cultural activity where people congregate, interact, and escape the clamor of the city. These areas are crucial in determining a city's identity, character, and citizens' well-being and standard of living. Public spaces can define our communities and significantly impact how we live, work, and interact with one another through their architectural designs, facilities, and activities. Furthermore, they provide leisure, exercise, and recreation opportunities, allowing individuals to escape the confines of their daily routines and connect with nature.

This week's curated selection of Best Unbuilt Architecture highlights projects submitted by the ArchDaily community showcasing different proposals made to enhance public space. Ranging from reimagining central squares to placing massive land art in the urban epicenter, these public spaces enhance the quality of life for the city's locals. In Germany, the redesign of the entire Memorium Nürnberger Trials reimagines this as a place to come together, grounded in its history, while in Havana, the new Cuban Square reimagines the metaphor of unity in the city center. The design and accessibility of public spaces significantly impact our well-being and quality of life. Thoughtfully planned and inclusive spaces with seating, greenery, and pedestrian-friendly infrastructure can promote physical activity, mental health, and community engagement in a city.

For many, schools and kindergartens represent the first contact with public architecture. They, together with every educational facility, serve as the foundation for learning and knowledge dissemination, playing an important role in shaping the formative years of children and young adults. In consequence, these buildings need to respond to the needs of different age groups, while creating functional and flexible spaces for learning, but also for play and unstructured interaction. Light and ventilation needs contribute to the complexity of these architectural programs. However, designing educational facilities presents opportunities for innovation and creative expression, as they are required to adapt continuously to the changing needs of students and faculty while creating a conductive environment for learning.

This week’s curated selection of Best Unbuilt Architecture highlights designs submitted by the ArchDaily community dedicated to cultural institutions. From a learning center created to offer the girls in Mozambique an equal opportunity to learn, play and connect, to a naval station redesigned as a research center on the coast of Puerto Rico, this selection features projects created to encourage learning, curiosity, and the exchange of knowledge and expertise. The article includes designs from both established and emerging architectural practices, including Moore Ruble Yudell, C+S ARCHITECTS led by Carlo Cappai and Maria Alessandra Segantini, Hello Wood, and snkh studio.

Master plans, or large-scale urban planning projects, are one of the main tools for shaping and structuring land use and development to ensure that the built environment is coherent and functional. The interventions vary in scope and approach. While some projects are extending the buildable area by creating floating neighborhoods off the coast of Florida, others are reusing the existing spaces and heritage to reimagine the future of their communities.

This week's curated selection of Best Unbuilt Architecture highlights large-scale urban design projects submitted by the ArchDaily community Offices such as Aedas, LDA Design, Proctor & Matthews Architects, WTA Architecture + Design Studio are showcasing designs that create or reimagine entire neighborhoods, whether on land or on water, in cities all over the world, from Ukraine to Malawi, India or the Philippines.
