Rear extension drawings for a house extension in Redbridge
A house extension in Redbridge can go back 3 metres at the rear under permitted development, or 6 metres with prior approval, and anything larger needs a householder application, on which the council granted 83% of 991 decisions in the four quarters to 2026 Q2. DrawingsDirect draws rear extensions from £695.

Three ways to extend a house in Redbridge
The first is permitted development. A single-storey rear extension on a house that is not detached may extend up to 3 metres beyond the original rear wall without an application. The second is prior approval, which allows up to 6 metres on the same type of house once the council agrees (GPDO 2015, Schedule 2, Part 1, Class A, on legislation.gov.uk). The third is a householder application, which has no fixed depth limit but is judged on its design and its effect on the neighbours.
Houses in Woodford, Wanstead, Ilford and the rest of the borough can use any of the three, subject to their own conditions. Our permitted development explainer lists them.
The Redbridge householder record
Redbridge decided 991 householder applications in the four quarters to 2026 Q2, including prior approvals, and granted 83% of them (our analysis of MHCLG planning application statistics, table PS2).
The percentage covers every type of householder scheme, from a small porch to a large extension, so treat it as background. What it cannot tell you is how a particular rear extension will be received, which depends on the drawings and on the neighbours.

If Redbridge refuses: the appeal record
Our analysis of the Planning Inspectorate Casework Database counts 271 householder appeals decided for Redbridge between 2021 and 2026, with 40% allowed. Only applicants who disagreed with a refusal appear in that group, so it is not the borough's refusal rate.
It is a reminder that the plans and elevations are the evidence an inspector reads as well. Our planning appeal process guide sets out how an appeal works and what it asks of the drawings.
Where prior approval stands in the borough
In the eight quarters to 2026 Q2 Redbridge determined 308 larger home extension prior approvals and granted 29% of them (our analysis of MHCLG planning application statistics, table PS1). The count leaves out notifications the council decided did not need approval, so it does not describe every extension of 6 metres.
Because most of the notifications the council examined closely were refused, we study the neighbours' side of the plot before suggesting the 6 metre route. The prior approval guide covers the process.
