FACTORY IPSEN juin 2025 ©Yann Deret-8578.jpg

Ipsen establishes its new Paris headquarters on the edge of Parc André Citroën, in collaboration with Factory.

Ipsen is a global biopharmaceutical group dedicated to developing innovative medicines for patients across three key therapeutic areas: Oncology, Rare Diseases, and Neuroscience. Its R&D portfolio builds on both internal and external innovation, backed by nearly a century of expertise and development anchored in global hubs across the United States, France, and the UK. With teams in over 40 countries and partnerships spanning the globe, Ipsen brings its treatments to patients in more than 100 countries.

After recent real estate projects in London and Cambridge, the spotlight turned to Paris. The mission: unite Ipsen’s Paris-area teams under one roof worthy of their ambitions. That’s when we stepped in.

Designing tomorrow, today.

More than that, we brought a forward-looking perspective. Our “future at work” approach — combined with our ability to pick up a project already underway — proved to be a game-changer. By anticipating future work styles and getting involved early, even before the foundations were laid, we were able to go faster and further.

From the moment the call for proposals went out, our vision was clear: align Ipsen’s ambitions with the unique architecture of the building.

Factory brought a bold, coherent, and disruptive vision to the table — and the belief we could make it happen.

A triple transformation for Ipsen.

Now, everyone is together within central Paris — in a space that’s optimized, coherent, and efficient.
Second, a cultural shift: a move to flexible workspaces — which means saying goodbye to assigned desks. In their place: open, dynamic environments designed for movement, collaboration, focus, or stimulation, depending on the moment.

This new headquarters marks three major shifts for Ipsen.
First, a spatial shift: gone is the fragmentation between Boulogne-Billancourt and Les Ulis.

And finally, a symbolic shift: this isn’t just about co-location. This address is a statement of intent — a showcase for the company and its culture.

Putting people first.

We took full advantage of the site’s location next to Parc André Citroën to cultivate a real connection with nature, natural light, and breathing space.
Each of the seven floors features distinct “destination areas” with strong identities:
– a quiet library to refocus,
– a scenic lounge for spontaneous conversations,
– a modular space to support teamwork and collective intelligence.

From day one, our guiding principle was simple: design a workplace that feels alive. Warm, open, inspiring.

Every level brings its own energy, yet together they weave a consistent narrative — a space tailored to the diverse rhythms of daily work and the individual needs of Ipsen’s teams.

Flexibility, comfort, and thoughtful design.

Flexible working means being especially mindful of posture, pace, and flow.
Varied seating, height-adjustable desks, natural materials, and purposeful volumes: here, design is never just decorative — it serves the user experience.

We weren’t looking to impress. We aimed to simplify, clarify, and soften. To create a true ecosystem for work — one built around the people who bring it to life.

A sensory atmosphere with depth.

Warm tones (terracotta, beige, greige), raw materials, custom or carefully sourced furniture — every detail contributes to a soft, welcoming atmosphere. The space is punctuated by the artwork of Henri Beaufour — grandson of Ipsen’s founder.

Natural light is abundant. Acoustic comfort is finely tuned. And greenery is anything but ornamental — it’s everywhere.

Nature inside and out.

In harmony with the building’s wood-and-glass extension, designed by the architect, we infused greenery into every corner: solid wood in passageways, lush indoor plants, tree-lined balconies, and a rooftop transformed into a sky garden — complete with a vegetable patch, flowers, and shrubs.

The result? Teams describe the space as calming, refined, beautiful, and restorative — but most importantly, vibrant, with the kind of energy that simply feels good.

A strong identity, a curated experience.

This headquarters also offers a new way to tell the Ipsen story. More fluid, more contemporary, more human. From the moment you step inside, the poetic DNA-shaped chandelier — created with Komut — greets visitors and affirms the company’s scientific mission.
Every space becomes a tool for connection, reinforcing Ipsen’s company culture with elegance and meaning.

This isn’t just a workplace — it’s an international showcase for Ipsen. We’re not talking about brand image. We’re talking about culture.

A holistic work experience.

Exceptional service design is a core part of the project. After visiting our own offices, Ipsen CEO David Loew was inspired to replicate the Factory model for the company’s catering experience: a social hub with flavorful, diverse cuisine and high-quality table service. The result? A brand-new, professional 200m² kitchen capable of serving 450 meals per day — designed and built entirely by our teams.

And that’s not all: terraces with planchas and garden beds, cafés with baristas, a dedicated wellness and fitness space... Every detail was designed to enhance the daily lives of employees. Working here also means living well here — experiencing this headquarters not just as a workplace, but as a space for community and connection.

A tightly managed, high-impact project.

Our greatest pride? Merging functional excellence with emotional design, down to the finest detail. In the end, Factory and Ipsen teams worked hand in hand to create more than a workspace — we crafted a place for meaningful connection. A space where collaboration, performance, focus, and innovation come together — fully aligned with Ipsen’s vision.
This project came to life thanks to the vision of Ipsen’s leadership — and the teams who stood behind it every step of the way.

We delivered a fully controlled, high-standard project in just eight months of construction — despite tight deadlines and high technical demands.

Eight months. Intense constraints. An exacting level of finish. We stayed the course. But what truly matters to us is this: we reconciled high standards with emotional resonance. And we did it through co-creation, with careful listening, precision, and commitment.

We didn’t just design a space. We shaped a place of identity, performance, and connection — a place that brings Ipsen’s vision to life.

Transforming a headquarters into a strategic asset.

Delphine d’Amarzit

A redesigned, high-performing headquarters that stays true to Euronext’s identity.

The group is the leading stock exchange operator in Europe, managing the markets of Amsterdam, Brussels, Dublin, Paris, Lisbon, Milan, and Oslo. Euronext's offices in La Défense house both its French subsidiary and embody the group’s strong European identity.

As the European leader in capital markets with over 25% of equity trading across Europe, Euronext plays a central role in the continent’s economy.

A symbol of European finance since its founding in 2000, Euronext continues to assert its influence — a strategic and emblematic dimension that truly inspired us at Factory!

A major challenge: reinvent without relocating.

After a decade outside of central Paris, Euronext had to choose between staying in its unattractive, sparsely populated La Défense offices — largely abandoned by teams now accustomed to remote work — or relocating to a more appealing but costlier location. After negotiations with its landlord, the company opted for a third path: staying while transforming its premises into a space that matches its ambitions.

Our “The Future at Work” approach focused on three key pillars: optimizing workspace performance through a new layout and shift to flex office, enhancing employee well-being with more and better-adapted collaborative areas — brighter, more welcoming spaces including a fully redesigned restaurant — and strengthening the sense of belonging by turning the office into a true tool for collaboration and brand identity.

"A fourth challenge emerged: carrying out the work in an occupied building, while optimizing space without expanding its footprint — quite the feat! "

With support from Convictions RH, a consulting firm specialized in HR transformation, we guided Euronext through its transition to flex office while respecting team identities. It was essential to size the space correctly based on remote work policies and to ensure it could host Euronext employees from across Europe visiting Paris. We also carefully organized the spaces to encourage the right kinds of interaction — from small or large group meetings to remote calls in acoustic booths, or informal chats in alcoves and coffee corners.

Our first goal was to adapt the space to the real needs of employees.

As the work was done in an occupied site, the project required meticulous planning, smooth communication, and a strong change management process to support employees, ensure pleasant working conditions during renovations, and give them ownership of their new environment.

Putting people at the heart of the workplace.

We focused on making spaces brighter and more open, improving flow and comfort to foster better interactions — in short, unlocking the full potential of the office. To further enhance workplace appeal, we completely redesigned the food services.

The transition to flex office only made sense if it benefitted employees. 

We created a true restaurant with quality furniture, a dedicated coffee shop area for morning breaks with a real barista-style menu, and a diverse, high-quality lunch offering. Where employees once left the building at lunchtime, the new space has become a favorite gathering spot.

An iconic HQ for a strong brand.

We reimagined its flagship areas, which Euronext now calls its “remarkable spaces.” The previously impersonal lobby was upgraded with large exterior-facing screens that proudly display the Euronext brand. We also redesigned the bell-ringing ritual — a symbol of stock market listings that was previously underutilized. To elevate this experience, we collaborated with Europe’s oldest foundry to recast a more imposing bell and installed it in a high-ceilinged room with a panoramic view of Paris. At a time when everything is becoming digital, we were keen to preserve a physical ritual and celebrate European craftsmanship.

Despite its strategic importance and its role as the home of the Paris stock exchange, Euronext's office did not reflect its identity.

The on-site museum was also redesigned to create a dialogue between historic archives — including the famous trading pit of the former Paris Bourse, now repurposed — and contemporary installations such as a “sound shower” recreating the atmosphere of trading floors. These spaces tell the story and bring the Euronext brand to life — a key factor in strengthening both employee connection and public visibility.

### A transformative project.
Today, teams have fully embraced the new workspace — so much so that early skeptics have become the project’s strongest advocates. As Delphine d’Amarzit, CEO of Euronext Paris, puts it: _“This project marked a real turning point for Euronext. Thanks to Factory, we’ve turned our headquarters into a high-performing, people-focused workplace that reflects who we are.”_ A vision shared by Stéphane Boujnah, CEO and Chairman of the Managing Board of Euronext: _“Euronext is a company resolutely focused on the future. I thank Factory for transforming our offices into a powerful symbol of our history and ambitions.”_

### A bold project — just like Euronext and Factory!

Green innovation and exceptional office-laboratories.

Patrick Torbey

A unique space dedicated to green tech.

This dream became a reality when Patrick Torbey, a PhD in synthetic biology from ENS, crossed paths with Lionel Mora, who had spent some time at Google.

Neoplants was born from a dream: what if our indoor plants could purify the air we breathe?

In 2018, through the Entrepreneurs First program at Station F, Neoplants was founded and has since become a key player in green tech.

Find a hybrid space to support growth and innovation.

The initial offices, developed in partnership with Factory at the Institut des Plantes de Saclay, quickly became too small to accommodate the company’s rapid growth. Neoplants once again turned to Factory to help them find new workspaces closer to Paris, where they could bring together offices and laboratories. 

The goal was to create the ideal space for their first concrete projects and early prototyping. The challenge was significant: finding a location that met the high technical standards of a laboratory while remaining within the first ring of Paris, all within a tight 12-month timeframe from the start of the search to the completion of renovations.

The founders of Neoplants were immediately captivated by the vast glass roof and the potential of this unique space.

The goal was to establish the framework for our search by outlining the project’s scope. Since no such hybrid space existed near central Paris, we had to create it.

First, we guided them in defining their real estate strategy and project requirements in the short, medium, and long term.

In line with the tradition of repurposing Saint-Ouen’s industrial heritage, we discovered a former 1,200 m² shoe warehouse that needed to be completely transformed.

Facilities combining laboratories, offices, and team well-being.

We relied on the invaluable expertise of an engineering firm, which helped us develop the layout, particularly the laboratories—an infrastructure unfamiliar to Factory at the time. This collaboration allowed us to grow and demonstrated our ability to bring together top-tier expertise for a company’s project and its users. Additionally, while the green tech sector typically does not consider office spaces as a marketing tool, Neoplants strongly believed in the importance of having offices that were both functional and attractive for their teams and broader ecosystem, including investors, journalists, and public officials.

Our challenge was to design spaces that met the strict requirements of a synthetic biology lab—temperature control, humidity levels, lighting, air treatment, rigorous safety standards, and floors resistant to corrosive substances—while ensuring they remained pleasant environments within a residential neighborhood. For the interior design, we set up the teams in a spacious open-plan office under the glass roof, warming up the space with terrazzo, Socialite Family furniture, custom fittings, and vintage pieces, complemented by essential greenery for Neoplants.

Every new visitor—whether employees, journalists, clients, or investors—gets a tour of the offices, as they perfectly embody the company’s mission: leveraging synthetic biology advancements to enhance well-being. 

This project marked a turning point for Neoplants, becoming a key element of their branding and communication strategy.

With 95% of employees satisfied with their work environment, the teams greatly appreciate the balance between laboratory space (700 m², including 36 workstations in experimental labs and the humidity control center) and a 500 m² open space—an enthusiasm shared by the company’s founder.

### This project was also a milestone for Factory, pushing us to tackle unprecedented technical challenges.

It reinforced our ambition to support companies that shape the future. By integrating laboratories directly into their office spaces, Neoplants has created a powerful tool for growth. Their new environment has fostered a new way of working, encouraging collaboration between R&D and operational teams—an essential factor in building a unified, engaged collective working towards a common goal. Seeing, talking, and understanding one another creates real shared value.

Unique offices combining a winter garden vibe, collaborative workspaces, and modern comfort.

Julien Vivier

A successful transformation thanks to Factory's unique support.

Voted Mobile Marketing Agency of the Year in 2023, it helps high-audience brands by designing interfaces and applications used by millions. As their office became too small, they wanted to move their teams into a larger, more characterful space without leaving their beloved Montparnasse neighborhood.

GO & UP is one of those agencies on the rise.

We began by supporting them in their real estate strategy. By taking the time to understand their exact needs, we were able to find them a unique space with remarkable features: impressive ceiling height, a monumental glass roof, and an exposed stone wall—all elements that give the place a distinctive charm.
