In Woluwe-Saint-Lambert, as everywhere in the Brussels Region, a garden shed is exempt from planning permission if it meets every condition of the Order of 13 November 2008, including a maximum floor area of 9 m² and a maximum height of 3 m. Above that, you apply for a permit at the Woluwe-Saint-Lambert planning department. The full conditions are set out in our guide to garden sheds in Brussels. This page covers what happens locally: where to submit your application in Woluwe-Saint-Lambert, who to contact and what the municipality can require on top.
The exemption conditions at a glance
Your garden shed in Woluwe-Saint-Lambert is exempt from planning permission if all of these conditions are met:
- 9 m² maximum floor area (footprint, roof overhangs included);
- a height of 3 m maximum;
- located in the courtyard and garden area, respecting the 45° plane from the party walls (1.5 m at the boundary line);
- detached from the main building and its annexes, and not used as living space;
- 50% permeable surface kept in the courtyard and garden area (RRU, Title I, art. 13).
The exemption no longer applies if the property is less than 20 m from a protected heritage site, or if the shed departs from the RRU, a municipal urban planning regulation or a PPAS. The details and special cases are in the guide to the Brussels rules. If in doubt, a call to the Woluwe-Saint-Lambert planning department avoids unpleasant surprises.
