Summary and analysis of Brussels' current office real estate market conditions.
2025 was a strong year in terms of transaction volume, ough this masks a significant decline in deal count. Take-up recovery is largely driven by Grade A assets and replacement demand.
Vacancy declined modestly to 7.8% at the city level. However, the relatively substantial speculative completions planned for 2026 suggest that vacancy rates will likely increase again in the near term.
Prime office rents were confirmed at €400/sq.m./year in the European District while remaining stable in other districts. City-wide average rents eased from their previous peak to €190.9/sq.m./year (-1.2% QoQ, +6.4% YoY).
