The leading trade event for commercial real estate fresh new vision with key theme: “bringing people together”
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.
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.
