New-build house €/m² in Walloon Brabant rose +13% since 2022.

Walloon Brabant remains the most expensive Walloon province, driven by proximity to Brussels and land pressure (Ottignies-LLN, Wavre, Waterloo). Mandatory EPC-A and material costs sustain the upward dynamic.

Walloon Brabant pitfall to avoid

The clay soils of the Brabant plateau.

On the southern half of Walloon Brabant (Genappe, Court-Saint-Étienne, Chastre), swelling clay soils cause cracks and deformations within 5 to 10 years if foundations are undersized. Always demand a G2 soil study before signing, check continuous footing or raft foundations, and perimeter drainage at reception.
