Land real estate expertise in Brussels

Certified expertise of your land in Brussels

The appraisal of land in the Brussels-Capital Region constitutes a particular valuation exercise, substantially different from that of a building. The value of a plot depends almost exclusively on its development potential, itself determined by the planning regulations in force. Unlike a land appraisal that provides an indicative range, the certified expertise produces an enforceable report in the context of an inheritance, a donation, a mortgage or legal proceedings.

Our firm masters the specificities of Brussels land: high urban density, scarcity of available plots, and the complexity of the regional regulatory framework.

The particularities of land in Brussels

Scarcity and land pressure

The Brussels-Capital Region covers 161 km² and has a population of over 1.2 million. Building plots are scarce and expensive, which confers significant value on every developable square metre. Land prices vary considerably by commune and district: from 200 EUR/m² in some transitional zones to over 1,500 EUR/m² in the most sought-after districts.

The PRAS and the RRU

The developability of land is determined by two main regulatory instruments:

• The Regional Land Use Plan (PRAS): It defines the designated use of each plot (residential zone, mixed zone, enterprise zone, park zone, etc.). Only plots located in a developable zone may accommodate a real estate project.
• The Regional Urban Development Regulation (RRU): It sets the rules on massing, layout, density and architectural quality applicable to each zone.

The expert analyses in detail the regulatory situation of the land to determine the effective development potential: number of floors permitted, buildable depth, setback from the building line, maximum floor area.

Soil contamination

The ordinance of 5 March 2009 on the management and remediation of contaminated soils in the Brussels-Capital Region requires a soil investigation prior to any land transfer. If the soil is contaminated, the remediation costs, which can be very high, must be deducted from the value of the land. The soil condition inventory (managed by Brussels Environment) is systematically consulted.

Plot subdivision

When a large plot can be divided into several developable lots, the overall value may significantly exceed that of an undividable plot. The expert assesses the subdivision potential taking into account the PRAS, access to the road network and any easements.

Land appraisal methodology

Land valuation relies on specific methods:

• Comparison method: Analysis of recent transactions involving plots of comparable size, location and potential. Adjustments for differences in developability and accessibility.
• Developer’s residual land value method: Estimation of the residual land value by deducting all costs (construction, professional fees, financing costs, margin) from the sale price of the completed project. The reference method for plots with significant development potential.
• Opportunity cost method: For non-developable plots, value is estimated based on the most probable alternative use.

Content of the report

• Cadastral identification: References, official area, plot plan.
• In-depth planning analysis: PRAS, RRU, any PPAS, permitted massing, easements, listing.
• Soil condition: Consultation of the soil condition inventory, assessment of contamination risk.
• Accessibility and services: Road access, connection to utilities (water, gas, electricity, drainage).
• Reasoned fair market value: With detail of the retained method and calculation parameters.
