Stadim Focus Office Market Belgium: Market Report 2025

The Belgian office market closed 2025 in a context of gradual stabilization. Economic growth was around 1.2%, while inflation fell to an average of around 2.5%. Lower short-term interest rates and a stable 17-year OLO around 3.70% provided more price transparency and confidence. The market moved from a correction phase to selective renewed investment activity. The investment volume remained below the historical average, but clearly focused on sustainable and future-proof offices. The polarization between prime and obsolete buildings continued. Prime rents in Brussels remained around €400/m², with a rental premium of 5-10% for BREEAM Excellent or Outstanding assets.
