Rear extension drawings for Kentish Town homes

DrawingsDirect's starting fixed fee for single-storey rear extension drawings is £695 with no VAT to add, and that price is on our published price list.

What the £695 covers and what it does not
£695 is our starting fixed fee for single-storey rear extension drawings, survey and planning or permitted development drawings, with no VAT to add. It is the figure on our published price list, so you can read it before you speak to anyone.
It is a drawing fee. It is separate from the council's application fee, which is paid to Camden, and from any building work. If you are comparing a kitchen extension quote from a builder, the builder's price and our drawing fee are two different lines.
How far can a rear extension go before it needs planning permission?
Under the General Permitted Development Order, a single-storey rear extension on a house that is not detached may extend up to 3 metres beyond the rear wall of the original house. That limit sits inside a longer list of conditions in the same Class A, so 3 metres on its own is not a guarantee that no application is needed.
There is a second route for larger projects. A larger home extension, still on a house other than detached, can reach up to 6 metres beyond the original rear wall, but only through the prior approval process rather than by simply building.
A plan with the original rear wall marked, the new wall dimensioned from it and the boundary shown makes the 3 metre and 6 metre questions answerable on paper, which is the job of the drawings.
Over the latest eight quarters of published figures, Camden determined 7 larger home extension prior approvals, counting both granted and refused.
Camden's recent householder decisions
Camden decided 394 householder applications across the latest four quarters of published figures, counting prior approvals in that total. Of those, 89% were granted. We worked this out from the government's planning application statistics, and the source is listed at the foot of this page.
Over the same four quarters, 61% of householder decisions were made within eight weeks, with prior approvals left out of that calculation. If you are planning building work around a start date, that is a more useful number than the granted rate.
These are figures for the whole borough and for householder applications of every kind, not only rear extensions. They describe the past and say nothing certain about how your own application will go.
Appeals and conservation areas around Kentish Town
The Planning Inspectorate's casework database shows 135 householder appeals decided for Camden in the period we analysed, and 32% of them were allowed.
Camden also has 40 live conservation areas on the government's planning data platform. Whether your street is inside one changes what you can build without an application, so check this before you rely on the 3 metre figure.
Larger home extensions are rare in Camden's figures
Over the latest eight quarters of published figures, Camden determined 7 larger home extension prior approvals, counting both granted and refused. That is a small number beside the 394 householder decisions above, so most extension decisions in these figures sit outside the prior approval route.
If you want the 6 metre depth, it is that route you would be using, so it is worth deciding early whether the extra depth is worth it.
The Camden fee for a householder application
Under the current national fee table, the fee for a householder application to enlarge, improve or alter a single dwellinghouse is £548. The fee is set by government and paid to the council.
Add it to the drawing fee and you have the paperwork cost of a rear extension application, before any consultant reports or building work.
Kitchen extensions, lofts and other work on the same house
Many searches for a kitchen extension in Kentish Town are really searches for a rear extension, because the kitchen is what usually goes into the new space. The drawings are the same set either way.
If you are also thinking about the roof, a loft conversion is a separate drawing job with its own price and its own limits.
