Complete overview of new construction in Hainaut — dominant turnkey houses, off-plan apartments in urban hubs (Mons, Charleroi, Tournai), rural subdivisions — developers, regional taxation and pitfalls.
Hainaut remains one of the most affordable Walloon provinces across all segments. Gaps are notable between Mons (premium), Tournai (dynamic) and the Charleroi basin (more affordable). Mandatory EPC-A and land pressure keep the upward trend going.
Non-exhaustive list · factual information · we have no commercial ties with these players (deliberately so: our independence is our trade).
The former coal basin (Charleroi, La Louvière, Mons, Frameries, Châtelet) holds hundreds of kilometres of mining galleries, heterogeneous backfill and unstable slag heaps. You must consult the Walloon mining cadastre before the deed of sale and require a G2 soil survey — applicable to houses, buildings and subdivisions. The subsidence risk at 10-30 years remains real on many plots.
