How much can I build in Forest?
That depends on the plot: the area of the Regional Land Use Plan (PRAS) in which it lies, a special land use plan (PPAS) if one applies, the Regional Urban Planning Regulation (RRU) and the municipality’s regulations. For each address, the Perceelscan report states which area and which PPAS apply, with a link to their provisions; in Brussels, it does not yet calculate the m² of floor area.
Which special land use plans (PPAS) apply in Forest?
In Forest, 4 special land use plans apply, including the most recent ones: ‘PPA N° 12 ANCIENS ETANGS’ (1984), ‘PPA N° 4 RUE DE L'eau, rue de la soierie, rue de hal, rue bollinckx’ (1983), ‘PPA N° 5 QUARTIER DE L'avenue des villas’ (1966) and ‘QUARTIER DE L'avenue des sept-bonniers’ (1959). A PPAS only applies within its own area: for each address, the Perceelscan tells you whether one covers the plot.
Do I need a planning permit in Forest?
For most works, yes: building, renovating, demolishing and changing the number of dwellings generally require a planning permit, and some activities also need an environmental permit; some minor works are exempt. You can see which permits already exist for an address on openpermits.brussels; the Perceelscan report lists the files for the plot.
Is my property listed as heritage in Forest?
Forest has 44 protected properties (listed or on the safeguarding list) and 1,067 properties in the legal inventory of architectural heritage. As a rule, a protected property cannot be demolished; the inventory is not a form of protection. For each address, the Perceelscan tells you whether the building is protected, lies in a protection zone or is in the inventory.
Is there a right of pre-emption in Forest?
According to the register, there is no current pre-emption perimeter in Forest. The Perceelscan checks this for each address.
Which municipal urban planning regulation applies in Forest?
The urban.brussels register lists no municipal urban planning regulation (RCU) for Forest. The Regional Urban Planning Regulation (RRU) applies throughout Brussels; a municipality may have its own rules that are not in the register, so if in doubt, check with the municipality.
