Double storey extension drawings for Wallington homes, fixed from £995
A double storey extension in Wallington (SM6) is drawn in plan, elevation and section so that a householder application can show exactly what is being added. DrawingsDirect prepares double storey extension drawings from £995 with no VAT to add; the structural calculations and the council's householder fee of £548 are both separate.

Which council figures sit behind a Wallington extension
Our figures for this page are the ones published for Sutton, so that is the council this page speaks about. A householder application for a first-floor or two-storey addition is made on drawings, and the set has to show the existing house, the proposal and how the two relate.
Searchers in Wallington often type 'double storey wrap around extensions Sutton' or 'house side extension Wallington'. They are describing the same family of projects: an extension that adds a floor and, in many cases, wraps round the side and the back of the house. The drawing set is built the same way for each, and the shape of the wrap is what changes the plans.
What a double storey or wraparound set includes
Existing and proposed floor plans for both floors, existing and proposed elevations, at least one section through the new roof and floor, a block plan and a location plan. A wraparound adds the side and rear walls on the ground floor and, usually, a new room or two above.
The structural calculations are a separate fee: £745 from a named, insured engineer we work with, or your own engineer's figures drawn onto our set. They matter on a two-storey job because a wall that carries a first floor needs beams, foundations and openings sized before a builder can price it, and it is cheaper to settle that on paper than on site.
The published price for a double storey extension is £995 with no VAT to add, and sits on our public price list. The council's fee of £548 for a householder application is on top and is passed on at cost.
The Planning Inspectorate's database records 139 householder-development appeals decided for Sutton, and 41% of them were allowed.
The permitted development limits for going up
Some homes can add an extension without a householder application, but the rules tighten as soon as the extension is more than one storey. Under the General Permitted Development Order, a rear extension of more than one storey must not extend beyond the rear wall of the original house by more than 3 metres.
It also must not be within 7 metres of any boundary of the curtilage opposite the rear wall. On a typical suburban garden, that second limit is often the one that decides whether a project can be permitted development at all.
Both limits are measured from the original house, and other conditions in the Order can still apply. Because the drawings have to prove each measurement, we draw the existing house first and test the proposal against these limits before anything else.
What Sutton's householder figures show
Sutton decided 601 householder applications in the latest four quarters of published government figures, counting prior approvals. Of those, 92% were granted.
Of the householder decisions excluding prior approvals, 95% were decided within eight weeks. These are totals for all householder work, from small porches to large extensions, so they describe the whole caseload and not a double storey job in particular.
Those figures are not a promise about any single application. They show how many householder applications Sutton handled in the period, and a complete, clear drawing set is what an application is made of.
Appeals and designated areas to check first
Where an application is refused, the applicant can appeal. The Planning Inspectorate's database records 139 householder-development appeals decided for Sutton, and 41% of them were allowed. Read that as a record of how often appeals went either way, not as a forecast.
Before you design, check whether your road sits in a designated area. The government's planning data lists 15 live conservation-area entries for Sutton. Check your address against that list before you settle the design.
Separate from a householder application, the same government tables count prior approvals for larger home extensions. Over the last eight quarters, 98 of those were determined in Sutton, granted and refused together. It is a different application type, counted separately.
Neighbours, daylight and how the drawings answer them
People in Wallington search for 'daylight objections' because a taller wall near a boundary can cast shadow on a neighbour's window or garden. The drawings do not remove that concern, but they let it be looked at properly rather than guessed at.
We draw the new side and rear walls in section and elevation against the neighbouring building wherever it can be seen from the street or measured on site. Showing the relationship clearly, with the roof pitch and the height at the boundary, lets you adjust the design before you apply instead of after a letter arrives.
If you are weighing a side extension against a wraparound, ask for both to be drawn at the same level of detail so you can compare the effect on each neighbour.
How to start
Send the address, a few photographs of the rear and side of the house, and a line on what you want to add. We confirm the scope and the fixed fee in writing before any work begins, and the council's fee is shown separately so nothing is bundled into the headline figure.
