Understanding the new house price in Belgium requires distinguishing three things that are too often confused: the gross construction cost (structural work + finishes excluding the land), the turnkey sale price (which includes the developer’s margin, connections, taxes) and the total cost price (land, notary fees, connections, outdoor works, financing). Confusing these three envelopes leads to budget overruns of 15 to 30%. This guide gives the updated 2026 ranges and the structuring items to anticipate.

Price-per-sqm ranges in 2026

In 2026, the new house cost turnkey (excluding land) sits in the following ranges, based on cross-data from the firm on recent files:

Basic energy standard (EPC A, traditional structure): 1,500 to 1,850 €/sqm excl. VAT
Intermediate standing (heat pump, double-flow ventilation, careful finishes): 1,850 to 2,200 €/sqm
High standing (home automation, noble materials, custom architecture): 2,200 to 2,800 €/sqm and beyond
Certified passive house: 2,400 to 3,000 €/sqm depending on orientation and compactness

For a turnkey house of 150 sqm in intermediate standing, the house rate therefore comes out around 300,000 € excl. VAT, to which you must add the land, notary fees and outdoor works. The official figures published by Statbel confirm an average increase of 4 to 6% per year since 2022, mainly driven by materials and EPC requirements.

The items that (really) make the bill

The construction price breaks down into four main masses. The structural work (foundations, walls, slabs, roof frame, roof) represents 45 to 55% of the budget. The finishes (coverings, interior joinery, painting, sanitary) weigh 25 to 30%. The special techniques (electricity, heating, ventilation, plumbing) consume 15 to 20%. Finally the ancillary costs (studies, taxes, connections, EPC, controls) add up to 5 to 10% and are regularly underestimated.

Beyond the sqm, three variables strongly impact the price: the compactness of the volume (an L-shaped house costs 8 to 12% more than a simple rectangle), the energy equipment level (geothermal heat pump, photovoltaic, battery) and the standing of finishes (entry-level tiles vs. large-format porcelain stoneware). The firm regularly observes house price examples where “high-end” finishes at 600 €/sqm extra bring only a marginal resale margin: a choice to weigh up coldly.

Practical case: 150 sqm house near Namur

Let us take a concrete file handled by the firm in 2025: 150 sqm turnkey house, 4 bedrooms, 3 facades, 5 ares of land near Namur, EPC A.

Serviced land: 92,000 €
Turnkey construction (1,950 €/sqm excl. VAT): 292,500 € excl. VAT, i.e. 354,525 € incl. VAT at 21%
Connections (water, electricity, gas, sewers): 8,400 €
Notary fees for land: 11,200 € (Wallonia registration duties + fees + disbursements)
Outdoor works (driveway, terrace, fences): 18,500 €
Studies, urban planning taxes, EPC: 6,800 €

Total cost price: 491,925 €, i.e. 3,280 €/sqm related to the habitable surface. That is the real envelope to present to the bank, not just the “turnkey” price displayed by the builder.

Pitfalls to avoid when reading a quote

Quote “incl. VAT” without saying so: 21% hidden difference. Always require excl. VAT + incl. VAT in clear writing.
Items as “PM” (pro memoria): means “not costed” and will be invoiced in an addendum. Have everything costed.
Connections excluded: a new-house quote that omits connections hides 6,000 to 12,000 €.
Finishes “standard range”: without a precise description of references, the builder often substitutes at delivery.
Uncapped price revision: the Breyne Law frames the revision (article 7), require the full formula in the contract.
Missing outdoor works: terrace, driveway and fences cost 15 to 25,000 € rarely budgeted.

Securing your budget before signing

Before committing deposits, the firm systematically recommends having the contract and specifications audited by an independent third party. The extra cost (1,200 to 2,500 € depending on complexity) is marginal compared to the 300,000 € at stake, and allows you to renegotiate 3 to 8% of the price on average thanks to highlighting vague items, abusive revisions or exclusions.
