Planning in Southwark
Checked October 2026. Planning policy changes, so we confirm the position for your address before you commit.
The Southwark Plan 2022 was adopted on 23 February 2022 and is the main policy document for planning applications in the borough.

SourceRear extensions between 3m and 6m deep need to consider the impact on neighbours, with the roof sloping down towards the neighbour and staying below 2.4m; extensions over 6m deep on the boundary are likely to be refused, and rear extensions should not take up more than 50% of the rear garden (Householder Development SPD, 2025).
