Planning and permitted development in Merton
Many houses in Merton can extend under permitted development, but this depends on previous extensions, conservation constraints and dimensions. We confirm the safest route for each address, including whether a lawful development certificate is recommended.
Rear extensions
- Commonly 3 m to 4 m depths under PD
- Deeper schemes may use Prior Approval
- Height, boundaries and neighbour impact matter
- We set it out clearly in plans and sections
Loft conversions
- Volume limits typically 40 to 50 cubic metres
- Dormers sized to suit roof form and context
- Side windows normally obscure glazed
- Street appearance and overlooking considered
Flats and conversions
- Flats do not have PD rights
