3-year price trend

New-build €/m² in WB rose +13% since 2022.

All segments combined (houses, apartments, subdivisions, serviced residences), the province is the most expensive in Wallonia. Proximity to Brussels, land pressure in Wavre-Ottignies-Waterloo and the mandatory EPC-A keep the upward trend going.

Walloon Brabant pitfall to avoid

Clay soils of the Brabant plateau.

On the southern half of WB (Genappe, Court-Saint-Étienne, Chastre, Villers-la-Ville), swelling clay soils cause cracks and deformations within 5 to 10 years if foundations are undersized. Systematically demand a G2 soil survey — applicable to houses, apartments and subdivisions. Verify the raft slab or reinforced footings and the perimeter drainage at reception.
