Camden granted 89% of the 394 householder applications it decided in the four quarters to 2026 Q2 (our analysis of MHCLG planning application statistics, table PS2), so most householder schemes that reach a decision are granted. DrawingsDirect draws house extensions in Camden and Camden Town, with rear extension drawings from £695.

What the 89% grant rate means for your extension
The 89% figure covers all householder decisions, from small alterations to full rear and roof extensions, so it is a borough-wide average and not a forecast for your house. We cannot promise a result. It does show that Camden is not a borough where well-designed domestic extensions are routinely turned away.
The same statistics show Camden found prior approval was required on only 7 larger home extension notifications over the eight quarters to 2026 Q2 (our analysis of MHCLG planning application statistics, table PS1). With so few cases there is no meaningful rate to quote, and the route appears to be little used in the borough, so a householder application is the usual starting point.
Conservation areas decide a lot in Camden
The government's planning data register holds 40 conservation-area entries for Camden (our analysis of the MHCLG Planning Data Platform conservation-area dataset). Check your road on Camden's conservation area map before you plan, because your house may stand inside one.
In a conservation area the council reads an extension against the character of the street, so the drawings include the street-facing elevation, materials, and how the extension relates to neighbours. Our conservation area extension rules guide and the glossary entry set out the extra requirements.

The permitted development limits you start from
On a house that is not detached, a single-storey rear extension may go back 3 metres, and a larger home extension that needs prior approval may reach 6 metres (GPDO 2015, Schedule 2, Part 1, Class A). Rights can be removed by an Article 4 direction, which councils often use in conservation areas, so we check the register first.
Read the Article 4 direction guide if your road has been mentioned in a council letter.
What you pay: the council, then us
The statutory fee Camden charges for a householder extension application is £548, and the fee for a prior approval for a larger rear extension is £249, both from 1 April 2026. Our rear extension drawings start from £695, with other fixed fees on the pricing page.
Council figures above come from the MHCLG planning application statistics, which anyone can check.
How we start a Camden job
Send the address, a few photographs and what you have in mind. We check the designations on the road, say which application type fits, and quote a fixed fee. Our rear extension drawings page shows what a finished set contains.
