Rear extension drawings in Greenwich
Greenwich granted 55% of the 294 larger home extension prior approvals it determined in the eight quarters to 2026 Q2 (our analysis of MHCLG planning application statistics, table PS1), so a deep rear extension there has a real route. DrawingsDirect draws rear extensions in Greenwich from £695.

Prior approval for a deep rear extension in Greenwich
The standard permitted development limit for a single-storey rear extension on a house that is not detached is 3 metres. The prior approval route allows up to 6 metres, subject to the council's decision (GPDO 2015, Schedule 2, Part 1, Class A, on legislation.gov.uk).
Greenwich determined 294 of those notifications over eight quarters and granted 55%, which means refusal was still the outcome for close to half. Notifications where the council decided prior approval was not needed are outside both numbers, so they do not describe every deep rear extension in the borough. Our prior approval guide explains each stage, and the permitted development glossary entry lists the wider conditions.
Householder applications: 624 decisions, 77% granted
A rear extension that is deeper, wider or taller than permitted development allows needs a householder application. Greenwich decided 624 householder applications of every kind in the four quarters to 2026 Q2, including prior approvals, and granted 77% of them. Excluding prior approvals, 95% were decided within 8 weeks (our analysis of MHCLG planning application statistics, table PS2).
These figures describe the council's past decisions on all householder schemes. We make no promise about your application, and we draw for the case officer who will read it.

Kidbrooke, Westcombe Park and Blackheath: daylight and neighbours
Homeowners near Kidbrooke, Westcombe Park and Blackheath who look up daylight assessments are usually answering a neighbour's concern about a new extension. We do not carry out daylight or right to light assessments, which a specialist surveyor provides. We do draw the extension, the boundary and the neighbours' windows to scale, and those plans are the starting point for any assessment.
If the house has not been measured, our measured building survey gives you accurate existing plans first. For the planning-permission side, see how we prepare drawings for planning permission.
