Brussels Office Market Dynamics, Q1 2026

Transaction activity hit historic lows with take-up of only 40,496 sq.m., down 49% year-on-year—the weakest performance in 25 years due to geopolitical tensions slowing decision-making processes.

Market fundamentals remain stable despite low activity, with city-wide vacancy holding steady at 7.7%, prime rents confirmed at €400/sq.m./year in the European District, and Grade A space continuing to dominate transactions at 43%.

Investment market stalled significantly with only €82 million in transaction volume across the entire country, while the outlook suggests potential take-up recovery later in 2026 driven by EU deals, though vacancy may increase due to speculative completions.
