Siec is evolving to boost networking and expand opportunities for professionals in commercial real estate. Its mission: to highlight the growing diversity of roles and expertise in the industry.
For its 20th edition, Siec 2025 is focusing on: “BRINGING PEOPLE TOGETHER.”
From shopping to dining and leisure, commercial spaces are evolving into vibrant hubs of everyday life.
To boost their appeal, commercial spaces – from city centres to shopping malls – are enhancing and diversifying their offerings. They’re blending dining, entertainment, services, and a wider variety of brands, both local and international.
But it’s not just about the mix of options. What really sets these spaces apart is their ability to meet the rising expectations of visitors: seamless customer experiences (accessibility, security), stunning architecture and design, and exceptional service. This combination is what transforms commercial spaces from transactional hubs to vibrant, community-focused destinations.
Celebrating 20 years of growth and innovation, SIEC 2025 will showcase the diversity and dynamism of the commercial property sector.
Taking place on 11th–12th June 2025 at Paris Expo – Porte de Versailles, the event will be shaped by three key strategic focuses:
- A new experience for visitors and exhibitors with redesigned spaces, including a revamped Business Lounge, a dedicated Brand Club, and, most notably, a brand-new central Food Court. This welcoming space will provide food and refreshment options throughout the day without leaving the exhibition. A highlight of the event will be the Siec’s Grand Evening on 11 June from 6:30 PM, marking the fair’s 20th anniversary. Open to all, this festive event will offer a relaxed atmosphere to continue discussions and celebrate two decades of networking and innovation.
- A larger exhibition space of over 1,000 additional square metres, introducing new areas and themes to attract a broader audience:
o Cities & Territories Pavilion: Featuring cities such as Poitiers, Bordeaux, Pau, and Calais, this pavilion will showcase commercial opportunities to over 800 French and international brands.
o Solutions & Services Pavilion: Highlighting innovative solutions to enhance the efficiency and sustainability of commercial spaces, including eco-friendly technologies such as solar panels, EV charging stations, and energy management systems. This area will also showcase sustainable design firms creating low-carbon retail environments and property management solutions that promote more efficient and eco-conscious commercial operations.
o Marketing & Data Pavilion: Showcasing the key role of marketing and data in
improving customer experience and visitor insights. From spatial design to customer journey analytics, communication, and engagement strategies, this pavilion will offer a wide range of innovative solutions. It will complement the well-established Retailtainment Pavilion, adding a focus on personalised customer experiences and commercial performance optimisation.
• A diversified audience to establish Siec as the must-attend event for all commercial real estate professionals. The 2025 edition aims to attract more retail brands, marketing decision- makers, site managers, public sector stakeholders, and investors. To encourage participation, a revised pricing policy will make the event more accessible to a wider range of professionals.
For this anniversary edition, Siec will also introduce an exclusive content programme, featuring expert talks, industry debates, and case studies. Key players such as Altarea, QubicaAMF, Carmila, Savills, Klépierre, and Nhood have already confirmed their participation, ensuring high-level discussions and diverse insights into the future of the industry.
“Just like retail spaces, which are constantly reinventing themselves to meet evolving consumer needs, Siec is becoming a space for experiences and interactions. It remains a key event for all commercial real estate professionals, welcoming new brands and partners,” says Arnaud Gallet, director of Siec.
Key Theme: “BRINGING PEOPLE TOGETHER”
This year’s theme, “Bringing People Together”, highlights the fundamental role of commerce in fostering social connections and strengthening local communities. As places of interaction, engagement, and shared experiences, retail spaces play a central role in urban and suburban life. They connect people, revitalise city centres, and support local economic and social development.
“Siec 2025 will be a unique opportunity to explore the latest trends shaping customer journeys and experiences, connect with innovative brands, and engage in discussions in a dynamic setting. By broadening its exhibitor and visitor base, the event reflects the evolution of our federation, now representing all commercial spaces—not just shopping centres,” adds Christophe Noël, General Delegate of FACT.
