Double storey side return and wraparound extension drawings in Sutton
A double storey side return or wraparound extension in Sutton is a householder application, and the borough granted 92% of the 601 it decided in the four quarters to 2026 Q2 (our analysis of MHCLG planning application statistics, table PS2). We draw double storey extensions for planning from £995, survey included.

Prefer to talk it through?
Side return, wraparound or double storey: which is yours
The three names overlap. A side return fills the strip beside the back of a house, a wraparound adds that strip to a rear extension, and double storey means the new work rises over two floors. The forms are often combined, so the drawing set has to show the ground-floor footprint, the first-floor footprint and how the two meet the neighbours. Our side return extension drawings page and wraparound extension drawings page describe each form, and the side return against wraparound guide helps you choose.
Sutton's householder decisions
Sutton decided 601 householder applications in the four quarters to 2026 Q2 and granted 92%; 95% of the householder decisions that were not prior approvals were made within 8 weeks (our analysis of MHCLG planning application statistics, table PS2). Porches, dormers and garden-facing extensions all sit in that count, so read it as a borough-wide picture rather than a figure for two-storey work alone.
On appeal, 139 householder cases have been decided for Sutton since 2021 and 41% were allowed (our analysis of the Planning Inspectorate Casework Database). That is a record of what happened, not a forecast.
The national register holds 15 live conservation-area entries for Sutton (our analysis of the MHCLG Planning Data Platform conservation-area dataset), and Sutton's own conservation area map shows whether your road is one of them.
The limits that apply to a second storey
Where a second storey extends from the rear wall, permitted development allows it to project no more than 3 metres from the original rear wall and keeps it out of 7 metres of any boundary of the curtilage opposite the rear wall (General Permitted Development Order, Schedule 2 Part 1). Side additions carry their own conditions, which we check against your house at survey. Our double storey planning guide explains when a full application is needed.
Heritage, council fee and our fee
The national register holds 15 live conservation-area entries for Sutton (our analysis of the MHCLG Planning Data Platform conservation-area dataset), and Sutton's own conservation area map shows whether your road is one of them. Sutton also determined 98 larger home extension prior approvals in the eight quarters to 2026 Q2 (our analysis of table PS1), the route for deeper single-storey rear extensions.
The council's householder fee is £548 from 1 April 2026. Our double storey extension planning drawings start at £995, with the survey included; the double storey extension drawings page shows the set.
