Brussels Home Prices Match 2021 Peak as Core District Sales Surge

Brussels apartment prices have reached €4,850 per square metre in the first half of 2026, matching the peak levels recorded during the 2021 boom cycle when annual growth hit 8.2 percent.

The comparison matters because the city now faces similar supply constraints after two years of subdued construction permits, pushing buyers back toward established stock in central postcodes instead of waiting for new builds.

Price Patterns in Ixelles and Saint-Gilles

In Ixelles, two-bedroom flats near the Place Flagey now list at €5,200 per square metre, up 7 percent from the same period in 2021. Saint-Gilles properties along the Chaussée de Charleroi show parallel movement, with renovated townhouses selling for €4,900 per square metre after an average of 28 days on the market. Local agents report that demand from EU staff and Belgian families has replaced the investor wave that defined the earlier cycle.

Data from the Brussels Property Observatory records 2,140 residential transactions between January and June 2026, compared with 1,980 in the first half of 2021. Average sale prices in Etterbeek rose to €4,650 per square metre, while the city-wide median transaction value stands at €385,000, €12,000 above the 2021 equivalent when adjusted for inflation.

Buyer Steps in the Current Cycle

Prospective purchasers should review energy-performance certificates early, as properties scoring below D now face longer listing times than in 2021. Checking recent sales on the Avenue Louise and Rue Belliard provides a clearer benchmark than relying on asking prices alone. Contacting the regional housing agency for updated mortgage rules before making offers reduces the risk of last-minute financing shortfalls.
