New-build house for sale in Belgium: where to find and how to choose

Finding a new-build house for sale in Belgium in 2026 means combining online research, administrative checks and field audits before any commitment. The market offers three main sources: generalist portals, developer sites and specialised real estate agencies. Each has its biases, and the quality of the offer varies greatly. This guide helps structure the search, identify serious new-build house listings and validate an opportunity before signing the compromise or authentic deed.

Where to find a new-build house for sale in 2026

Three main channels concentrate the supply:

Generalist portals: Immoweb, Logic-Immo, Zimmo, Realo. Activate the “new” or “first occupation” filter. Advantage: maximum coverage. Disadvantage: listings are sometimes kept long after actual sale, and developers publish there in parallel with their own site. The belgium new-build sale market typically has 60 to 80% of its listings on these portals.

Regional developer sites: each major developer (Matexi, Eckelmans, Thomas & Piron, BPC Real Estate, Cordeel, BESIX RED, etc.) maintains a site with its catalogue of current programmes. Updates often faster, more detailed technical sheets, access to pre-reservation. Advantage: direct information. Disadvantage: no cross-comparison.

Specialised new-build real estate agencies: certain local players (notably in Brussels and Antwerp) are mandated by several developers for marketing. Advantage: a single interlocutor for several programmes. Disadvantage: commissions built into the final price, variable transparency.

Checks before visiting

Before travelling or signing the slightest reservation, several administrative checks are necessary:

• Building permit: issued, under review, or simply filed? The information is public. In Brussels, the permit is consulted via municipal planning services. In Wallonia, via the Géoportail portal. A project without an issued permit involves a risk of modification or blockage.
• EPC: any new-build housing must reach Q-ZEN (Quasi Zero Energy Net). Check the EPC-project certificates currently valid.
• Planning and sector plans: compatible zoning (housing zone, mixed), absence of heavy easements, flood risks (cartography available via regional portals).
• Developer: history, delivered references, balance sheets at the CBE, absence of recent collective procedure.
• Breyne Law applicable: any off-plan or turnkey purchase with down payment before full completion falls under the Breyne Law, with mandatory 5% security deposit. See Breyne Law.

Booming markets in 2026

Active new-build house developers in Belgium concentrate their programmes on a few booming areas:

• Brussels and periphery: stable market, high prices (€2,200 to €3,200/m² incl. VAT depending on municipality and standing), high density of VEFA programmes.
• Walloon Brabant (Wavre, Genappe, Ottignies, Nivelles): premium market, tight demand, prices €2,000 to €2,500/m² incl. VAT.
• Namur-Liège axis: dynamic market, opportunities in peripheral towns, €1,600 to €2,100/m² incl. VAT.
• Belgian Luxembourg: more moderate prices, demand driven by cross-border workers.
• Hainaut and Charleroi: calmer market, opportunities for first-time buyers, €1,500 to €1,900/m² incl. VAT.

The Statbel data allow tracking price developments by district.

Case study: selection of a new-build house in Wavre

Case 2024: couple searching, budget €480,000 incl. VAT all-inclusive, Walloon Brabant area.

Pre-selection method applied: 14 listings pre-selected on Immoweb and 3 developer sites. For each, verification: (1) issued and compliant permit, (2) EPC project certificate, (3) financial strength of the builder (CBE), (4) price per m² consistent with the local market. Result: 5 listings dismissed (permit not issued, insufficient EPC, developer in difficulty), 9 retained for visit.

Visits organised with a firm expert. Land audit + finish projection on 4 finalists. One project retained, pre-signing audit of the contract (3 clauses renegotiated), reservation then authentic deed. Estimated saving: €12,000 from renegotiation + full Breyne Law security.

Pitfalls to avoid

• Signing a reservation without security deposit: prohibited by the Breyne Law, demand the certificate.
• Believing the listing without checking the permit: it is public, check at the town hall or via the regional portal.
• Paying a reservation down payment > 5%: legal cap.
• Ignoring the developer’s financial strength: the CBE is free and public.
• Choosing the developer’s notary without having your own: it is free for you to have your own notary.
• Skipping the pre-signing audit: €1,800 to €2,500 to secure €380,000 to €600,000 of commitment.

Securing your new-build house purchase

Identifying a serious new-build house for sale is the first step, but the pre-signing audit is what really secures the investment. A critical reading of the contract, specifications, plans and schedule by an independent expert makes it possible to identify blind spots and renegotiate before you commit.
