Modernizing an Office Building in Neuilly-sur-Seine: A Sustainable Transformation

The "Rue de l'Église" project in Neuilly-sur-Seine, anticipated for completion in December 2025, represents a significant endeavor to upgrade a 1970s office building. The primary objective is to align this structure with contemporary benchmarks for employee well-being, operational efficiency, and seamless integration within its urban landscape. Instead of opting for a complete teardown and rebuild, the architectural firms, Vincent Lavergne Architecture Urbanisme and COVE Architectes, embraced a more environmentally conscious strategy, focusing on the transformation and intensification of the existing building through a comprehensive approach to its exterior, ground floor, and roof.

This transformative process addresses the building's three key dimensions: its exterior shell, its base, and its uppermost section. The facade is being re-envisioned to enhance aesthetic appeal and energy performance, while the ground level is undergoing modifications to foster greater connectivity with the surrounding urban environment. Simultaneously, changes to the roof are designed to optimize space utilization and introduce new functionalities, ensuring the building meets modern demands without sacrificing its inherent structure. This holistic renovation aims to rejuvenate the property, extending its lifespan and enhancing its functionality for future occupants.

This project serves as a compelling model for sustainable urban development, showcasing how existing infrastructure can be adapted and revitalized rather than discarded. By prioritizing renovation over new construction, it minimizes environmental impact and preserves the architectural heritage of the area, demonstrating a forward-thinking approach to real estate that benefits both the community and the planet.

Beyond Transit: Rethinking Architectural Passages as Vibrant Social Arenas

In the realm of architecture, the pathways that guide our movement through buildings are typically viewed as purely functional elements. Their primary role is to facilitate transit from one point to another, often receding into the background of our consciousness as we focus on our ultimate destinations, be it a classroom, an apartment, a gallery, or a public square. However, this perspective overlooks the profound impact these transitional zones can have on human experience and social interaction. This piece delves into the idea that certain memorable architectural encounters unfold not just upon arrival, but significantly during the journey itself through carefully conceived circulation.

Traditionally, the design of circulation elements such as corridors, stairwells, and walkways is approached with a pragmatic mindset. Their purpose is straightforward: to link distinct areas and organize the flow of people within a structure. Consequently, these interstitial spaces have often been relegated to a secondary status, perceived as subservient to the main programs they serve. The emphasis invariably falls on the destination, leaving the intervening spaces largely unnoticed and undervalued.

Yet, a paradigm shift in architectural thinking suggests that these conduits can be reimagined as vibrant social landscapes. When imbued with thoughtful design, they transcend their utilitarian function to become dynamic spaces that encourage spontaneous encounters, foster community, and enrich the overall spatial narrative. Instead of merely moving through a space, individuals can engage with it, finding moments of pause, interaction, and even contemplation. This innovative approach to designing pathways recognizes their inherent capacity to contribute to the social fabric of a building and, by extension, the broader urban environment.

By consciously integrating features that promote dwelling, interaction, and engagement within circulation areas, architects can unlock their latent potential. This might involve incorporating seating arrangements, natural light, unexpected vistas, or elements that provoke sensory experiences. Such design interventions transform mundane passages into micro-environments where the journey becomes as significant as the arrival, nurturing a richer, more connected human experience within the built world. These transformed passages not only serve as connectors but also as destinations in themselves, celebrating the often-underestimated social life of architectural circulation.

Exploring Multispecies Architecture: A New Paradigm for Design and Coexistence

Western thought has often positioned human culture in opposition to the natural world, a dichotomy that has profoundly influenced fields from science to humanities, including architectural practice. This perspective has typically reduced non-human elements to mere "natural resources" for human utilization, leading to an extractivist mentality that has left significant, often irreversible, damage on our planet. However, diverse cultures globally have long embraced alternative modes of existence. Examples range from animistic spiritual beliefs in West Africa and the botanical knowledge of Brazil's Sacred Jurema masters to Indian indigenous communities whose lives synchronize with monsoon cycles, and Arctic Inuits who discern myriad shades of white. These traditions highlight a fundamental interconnectedness between humans and nature, viewing all life as an integrated whole.

Contemporary thinkers are now bringing this crucial conversation into philosophical and architectural discourse. Scholars such as Donna Haraway, Antônio Bispo dos Santos, Achille Mbembe, and Beatriz Colomina are among those expanding beyond a narrow Western viewpoint, illuminating diverse approaches to coexisting harmoniously with both human and more-than-human entities on Earth. This month, ArchDaily is featuring "Transspecies Architecture: The Life of Materials, Ecological Alliances, and Nature's Agency." This theme aims to dissect architecture’s deep connections with resource extraction, land use, and the broader web of planetary life. It challenges conventional notions of sustainability as a performance metric, instead asking how building materials embody geological histories and political geographies, and how advancements in microbiological design, biofabrication, and partnerships with non-human life are redefining the very act of construction.

The current editorial focus will explore these complex interdependencies across various scales. It will meticulously track the entire production cycle of granite, from quarry to finished countertop, revealing the environmental and territorial costs embedded in everyday materials. The rapid ascent of bamboo from a traditional craft material to a modern carbon-sequestering infrastructure will be examined for insights into its complete life cycle. Furthermore, the discussion will elevate mold to an architectural subject, investigating how living organisms colonizing structures can challenge prevailing ideas about permanence and design intent. The series will also consider cities where dogs, cows, birds, and insects already share urban spaces with humans, pondering what architectural forms might emerge from designs that prioritize these diverse realities. Lastly, it will analyze how historical food production systems, driven by the metabolic requirements of animals and plants, have shaped coastal regions, influenced building typologies, and reconfigured entire landscapes.

The core inquiry behind this exploration is a powerful challenge to the long-held assumption that architecture should view matter and other species solely as resources to be exploited. What if, instead, they were recognized as active participants and collaborators, each with their own distinct temporalities, intrinsic tendencies, and unique characteristics? As these questions become more pressing, it becomes increasingly difficult to overlook their implications: What are the true ecological and political ramifications of the materials we frequently employ without a second thought? Is it possible to conceive of an architecture where accommodating non-human life is a foundational principle of design? And what new understandings might emerge when we consider a building’s ability to decompose, transform, and endure beyond its intended human purpose?
