What to know in Lasne
Lasne is in Wallonia. The works exempt from planning permission were redefined on 1 May 2025 (Article R.IV.1-1 of the CoDT). No exemption applies in a high flood-risk zone.
Local rules and grants
- In Lasne, the municipal planning guide does not list asphalt or poured concrete for driveways: grey natural stone, grey concrete pavers, fired clay, gravel, dolomite or grass pavers (gravel and grass pavers never on the first 5 metres).
- In Lasne, terraces, driveways and parking areas count towards site coverage, which is limited to 30% (35% in villages) of the buildable part; grass pavers that are grassed over do not count.
- In Lasne, a fence visible from the street must not exceed 1.20 m; PVC, woven wooden panels and hedges of thuja or cherry laurel are not allowed.
- Felling a tree over 40 cm in girth in Lasne needs authorisation from the municipal executive, and felling is only allowed from 15 August to 31 March.
The rules in Wallonia
| Ground-level terrace | No permit needed and no size limit, if it is at ground level and does not noticeably change the lie of the land. |
|---|---|
| Driveway and parking | No permit needed up to 300 m² if they are permeable and non-continuous (stabilised gravel, open-jointed pavers, grass pavers). Above that, a simplified permit, without an architect. |
