Breathing Life into Concrete: Thomas Heatherwick’s ‘Humanise’ Wall in Seoul

In the dynamic urban heart of Seoul, a powerful new public artwork is taking shape, one designed to challenge our very perception of the built environment. The “Humanise Wall,” a monumental 90-meter-long, four-story-high structure from the visionary Heatherwick Studio, is the centerpiece of the Seoul Biennale of Architecture and Urbanism. Conceived as more than just a public installation, the wall is a bold, tangible manifesto aiming to provoke a global conversation about how our cities—with their often-harsh, monolithic structures—affect our well-being. By using a seemingly simple architectural element, the wall, as a canvas for a deeper message, the project seeks to inject a sense of human scale, warmth, and emotion into a typically impersonal urban space, inviting citizens to reflect on the architecture that shapes their daily lives.

A Dialogue with the City

The “Humanise Wall” is strategically positioned in Songhyeon Green Plaza park, a location that places it in direct conversation with its urban surroundings. The contrast between the park’s natural, green landscape and the wall’s industrial materials is striking, immediately drawing the eye and sparking a dialogue about the relationship between nature and the city. The structure is built from chunky, red and black steel, a material palette that deliberately contrasts with the often cold and polished surfaces of modern high-rises. This choice of material gives the wall a raw, almost handmade feel, imbuing it with a sense of texture and humanity that is often absent in contemporary architecture.

The twisted, undulating form of the wall further amplifies this dialogue. It rejects the straight lines and rigid geometry of most urban construction, instead adopting an organic, flowing shape that feels more sculptural than architectural. This form is not just a stylistic choice; it’s a statement on the need for urban design to be more dynamic and empathetic. By subverting the typical form of a wall—a symbol of separation and enclosure—Heatherwick’s design transforms it into a point of connection, a public canvas that invites engagement from every angle.

The Architecture of Empathy

The project’s name, “Humanise,” is its central design philosophy. Thomas Heatherwick, who serves as the general director of this year’s biennale, has long advocated for a more human-centric approach to architecture, one that prioritizes feeling and experience over sheer functionality or scale. This wall is the physical manifestation of that ethos. Its purpose, as outlined by the studio, is to spark a conversation about how a city’s architecture affects people’s feelings, bodies, and behavior.

When completed, the wall will feature large-scale text, artworks, and images of buildings that embody the “Humanise” ideal. The featured projects are deliberately chosen for their ability to foster a sense of joy, wonder, or belonging, serving as tangible examples of how architecture can be a force for good. Projects like The Interlock by Bureau de Change and The Broad museum by Diller Scofidio + Renfro will be showcased, each a case study in creating spaces that feel vibrant and alive. The wall essentially functions as an open-air museum, using compelling visuals to argue for a more emotionally intelligent approach to urban design.

The Craft of a Living Wall

What makes the “Humanise Wall” so unique is not just its conceptual depth but its meticulous craftsmanship. The steel elements are given a raw, almost imperfect texture, a deliberate choice by Heatherwick to counter the sterile perfection of much of today’s architecture. The wall feels tactile and authentic, inviting viewers to get closer and experience its details. This “living” quality is further emphasized by the inclusion of smaller, interconnected wall sections. In total, 24 of these smaller walls are being built by a diverse group of creatives, from esteemed architectural firms like Kengo Kuma and Associates and MAD, to designers like Stella McCartney. This collaborative approach transforms the main wall from a singular object into a collective project, a tapestry of creative voices. Each smaller section adds a new perspective to the central theme, turning the entire installation into a microcosm of the “Humanise” campaign itself. The project is an impressive feat of logistics and collaboration, bringing together a global cast of designers to create a unified statement on the future of urbanism. The result is a structure that is both a reflection of one man’s vision and a culmination of many different voices.

Redefining Public Space

Ultimately, the “Humanise Wall” is a project that redefines the purpose and potential of public space. It demonstrates that a piece of architecture can be both a functional boundary and a powerful medium for communication. By placing this provocative artwork in a public park, the biennale is making a clear statement: the conversation about urban design belongs to everyone, not just to architects and planners. The wall is a catalyst for dialogue, a place where citizens can gather, reflect, and share their own thoughts on the cities they inhabit. As the Seoul Biennale of Architecture and Urbanism runs from September 26 to November 18, the wall will be the central physical anchor of its message. The “Humanise” campaign, which also includes a book and a radio series, will continue to expand the conversation beyond the physical installation. By creating a physical and digital platform for these critical discussions, Thomas Heatherwick and his collaborators are building a legacy that will extend far beyond the duration of the biennale. They are proving that architecture’s most profound impact isn’t found in a building’s height or size, but in its ability to connect with and enrich the human soul.
