The new house price per sqm is the indicator every future buyer pulls out first to compare two projects. Yet this ratio hides more than it reveals: depending on the items it includes, the same “1,800 €/sqm” can mean a finished turnkey house or a simple closed shell. To calibrate your comparisons on a solid basis, the official Statbel construction statistics serve as a neutral reference, complemented by the indices of the Construction Confederation. This page gives you the 2026 benchmarks by region and by standing, as well as the classic pitfalls to avoid before signing a compromise.

What the price-per-sqm ratio really covers

The construction price per sqm refers to the cost related to the net habitable surface (according to the regional EPC definition) or to the gross surface depending on the developer. This first ambiguity already explains 10 to 15% of gaps between seemingly comparable offers. The good-practice rule: require a detailed quote item by item and rebuild the ratio yourself on a homogeneous basis.

The structuring items of a standard construction rate per sqm include: earthworks and foundations, closed shell (elevation, slabs, roof, exterior joinery), finishing (ceilings, floors, paints, sanitary, basic kitchen), techniques (electricity, heating, ventilation, plumbing) and finishes. Some turnkey contracts include everything; others leave the kitchen, tiling, screed or even earthworks as options. A quote at 1,600 €/sqm without earthworks does not have the same value as a quote at 1,800 €/sqm all included.

To these items are added the off-construction costs: land, registration duties or VAT, notary fees, urban planning taxes, connections (water, gas, electricity, sewers), outdoor works (terrace, driveway, fences, garden). These extras typically represent 15 to 25% of the global budget and never appear in the displayed sqm ratio.

2026 benchmarks by region and by standing

In 2026, in Belgium, the following ranges are observed for a single-family new house in standard turnkey:

Entry-level (basic finishes, catalogue equipment): 1,600 to 1,850 €/sqm excl. VAT in Wallonia, 1,750 to 2,000 €/sqm in Brussels and Flanders.
Mid-range (EPC A, careful finishes, equipped kitchen): 1,900 to 2,350 €/sqm excl. VAT.
High-end (EPC A+/A++, noble materials, home automation, reinforced insulation): 2,500 to 3,200 €/sqm excl. VAT and more depending on benefits.

The new house cost per sqm now integrates technical standards far superior to those of ten years ago: double-flow ventilation, triple glazing, heat pump, reinforced insulation to reach regional EPC thresholds. These obligations explain part of the inflation observed since 2020: according to Statbel, the ABEX construction index has progressed by more than 25% between 2020 and 2025.

To place these benchmarks in a global project context, consult also our new house price (overview) and new-build notary fees to budget the off-construction.

Practical case: a misleading sqm ratio

A representative file recently audited by the firm: a family hesitates between two offers for a 4-facade 165 sqm habitable villa in Walloon Brabant.

Offer A: 1,720 €/sqm, i.e. 283,800 € excl. VAT. Attractive announcement.
Offer B: 1,950 €/sqm, i.e. 321,750 € excl. VAT.

At first sight, A is 38,000 € cheaper. But the audit item by item reveals that offer A excludes: earthworks (8,500 €), screed (6,200 €), tiling (12,400 €), kitchen (15,000 €), final interior paint (4,800 €). Once these items are added (46,900 €), offer A actually comes out at 2,005 €/sqm — i.e. more expensive than offer B which included them all. Without this reprocessing work, the family would have signed offer A thinking they were saving.

Pitfalls to avoid when comparing ratios

Comparing non-homogeneous bases: EPC habitable surface ≠ gross built surface ≠ floor surface. Always bring back to the same definition.
Forgetting off-construction: land and fees can represent 30 to 50% of the total budget depending on the municipality.
Underestimating “catalogue” options: the standard kitchen at 4,500 € quickly becomes 18,000 € with usual options.
Believing the incl.-VAT ratio = excl.-VAT: a project eligible for VAT 6% (main residence, conditions FPS Finance) does not have the same tax burden as a project at 21%. See VAT 6 conditions.
Neglecting addenda: a poorly drafted Breyne Law contract lets through tariff modifications during the site.

What to do before signing

Before any commitment, an adversarial audit of quotes is the most profitable investment of a construction project. The firm Mon Etat Des Lieux offers a Breyne Law support including critical reading of quotes, contract verification, specifications analysis and hunt for unfair clauses.

Frequently asked questions

What are the main 2026 benchmarks for new house price per sqm in Belgium?

Price ranges and conditions vary depending on the region, the standing and the exact nature of the project. The orders of magnitude given in this guide are a compass, but do not replace a personalised analysis.

Should I call in an expert to validate my file?

For structuring projects, an outside opinion is often profitable: it avoids contractual and technical blind spots. Our construction audit can step in before signing.
