Which route does an Angel extension take?
Most people searching for a house extension in Angel want to know one thing first: can it be built without a full planning application? For a house that is not detached, the permitted development rules let a single-storey rear extension go up to 3 metres beyond the original rear wall. A larger home extension under the prior approval process can go up to 6 metres.
Those limits apply to the original house, and they sit alongside other conditions in the rules. Which route fits depends on the design and on the address, so the drawings are normally where the answer is settled: the proposed plan shows exactly how far the extension projects.
Check the conservation areas before you rely on the limits
Islington has 41 live conservation-area entries in the national planning data platform. It is worth checking your street against the council's conservation-area list before you assume the permitted development figures above apply to your house.
If your home turns out to be in a designated area, the drawings need to show the existing building and the proposed change clearly enough for the council to judge the effect. That is a job for accurate measured drawings rather than sketches.


From 1 April 2026 a householder application for enlarging, improving or altering a single dwellinghouse costs £548, paid to the council.
What Islington decided on householder applications
Between 2025 Q3 and 2026 Q2, Islington decided 337 householder applications, and 93% of those decisions were grants. Of the householder applications that were not prior approvals, 97% were decided within 8 weeks.
These are borough-wide figures from the government's planning application statistics, not a prediction for any one house. They show the kind of record an Angel extension application joins.
Prior approvals and appeals in Islington
Over the eight quarters from 2024 Q3 to 2026 Q2, Islington determined 4 larger home extension prior approvals. That is a small number next to the householder applications decided, so the projection is worth settling on the drawings early.
Where an applicant disagrees with a refusal, the Planning Inspectorate decides the appeal. For Islington, 180 householder appeals were decided between 2021 and 2026, and 25% of them were allowed.

Rear extension, or something bigger?
If your plan is a single-storey extension at the back of an Angel terrace, the page on rear extension drawings in Angel covers that version of the job. For anything that adds more than a rear projection, use the enquiry form with your address and a description of what you want.
