Planning Permission & Building Regulations in Islington.
Whether a project in Islington needs planning permission, and how difficult that permission is to obtain, depends on the property: whether it is in a conservation area, whether it is listed, whether it is a flat with a freeholder, and whether the council has removed permitted development rights on the street. We check all of this at the first visit and tell you the route before any drawings are made.
We then prepare and submit whatever is needed to the London Borough of Islington: a householder application, a lawful development certificate for permitted development, listed building consent with a heritage statement, or prior approval for a larger extension. Building regulations are handled through an approved inspector or the council's building control, and party wall notices are served where a neighbour's structure is affected.
Because our architects prepare the drawings and our team builds from them, there is no handover between designer, agent and builder. One team is responsible for getting the approval and for building what was approved.

Islington: the houses and the planning rules.
Islington is Georgian and early Victorian London north of the Angel: flat-fronted brick terraces around the squares of Barnsbury and Canonbury, the grander villas of Highbury Fields, and the canal-side warehouses now converted to apartments. The conservation areas are extensive and many houses are listed.
We have refurbished houses in Highbury and the surrounding streets, and the pattern here is consistent: opening up a narrow terraced plan, adding a side or rear extension at lower ground level, converting the loft and restoring the front elevation. Islington's conservation team expects rear extensions to be subordinate and well detailed.
The Barnsbury, Canonbury, Highbury Fields and Duncan Terrace/Colebrooke Row conservation areas cover most of the district.
London Borough of Islington
Islington decides applications and applies Article 4 directions in most conservation areas, so rear extensions and roof changes generally need a full application.
Basements
The borough's basement policy limits depth and footprint and requires a structural method statement and impact assessment.
Listed terraces
Many terraces are Grade II listed; internal alterations, including removing walls, need listed building consent.

Planning Permission & Building Regulations in Islington: your questions.
Who decides planning applications in Islington?
The London Borough of Islington. Householder applications are normally decided within eight weeks of validation; listed building consent runs to the same timescale unless Historic England is consulted.
Do I need planning permission in Islington?
It depends on the property and the proposal. Permitted development covers many rear extensions and lofts, but not in flats, listed buildings or where Article 4 directions apply. We confirm the route at the first visit.
Which parts of Islington do you cover?
All of Islington and N1, including Gibson Square, Canonbury Square, Highbury Fields, Thornhill Road, Colebrooke Row, Liverpool Road, and the neighbouring districts. We are based in London and our teams work across central, north, north-west, west and south-west London.
