Enter the plot size and the ratio.

Before you buy a plot

  1. Make sure the plot is building land (bouwgrond / terrain à bâtir). Cheap land is often rural land where you cannot build a home.
  2. Ask the municipality (or your notary) for the planning information on the plot: stedenbouwkundig uittreksel in Flanders, renseignements urbanistiques in Wallonia and Brussels.
  3. Check the utilities at the plot boundary: water, electricity and sewer. Ask each supplier for a connection quote before you sign.
  4. Check access. Modular homes arrive by truck in large modules and are set in place by crane: road width, bends, slope and space for the crane all matter.
  5. Get a soil study before final pricing. The foundations, and their cost, depend on the ground.
  6. Ask about setbacks, rights of way and flood risk. They limit where the house can go on the plot.

  • The permit depends on the region: omgevingsvergunning in Flanders (filed online via the Omgevingsloket), permis d’urbanisme in Wallonia and in Brussels. Source
  • The plot must be zoned for housing (woongebied / zone d’habitat) in the regional and local plans. Land in agricultural or natural zones is not building land. Source
