House Extension Drawings in Highbury |

An Article 4 Direction applies across Islington, so check it before assuming Highbury permitted development survives. The character of Highbury is the yardstick a Islington Council officer measures a scheme against: Victorian terraces around Highbury Fields. A N5 property inside Angel loses part of its permitted development and generally goes to Islington Council in full. It is confirmed against London Borough of Islington mapping for the Highbury plot.

That mapping of Article 4 directions across Highbury happens before design, which is what keeps the Islington Council route predictable. What can be built on a Highbury plot is decided by the victorian terraces — the original rear wall position first, the Highbury Fields roofline second. The borough policy layer over every N5 address is set out on Islington planning. The Highbury survey then carries into building regulations drawings in Highbury if the project runs on to construction.

London Borough of Islington takes one to two weeks to validate a Highbury submission. The Highbury survey comes first, because a proposal drawn on wrong existing plans fails validation later.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

Highbury is characterised by victorian terraces, mansion blocks, concentrated across N5 in the Highbury area. The victorian terraces is the constraint that shapes most Highbury projects, long before policy enters the picture. Where Highbury is concerned, the side-return infill is the classic move on these Victorian terraces — 3 m of permitted development depth plus the width of the original side passage. We resolve it before the Highbury design is fixed. The prevailing Highbury eaves line is the reference Islington Council uses, which is why the proposed elevation is drawn with the neighbours on it.

A N5 dig turns on engineering more than on policy. One Highbury survey serves architectural drawings for N5 properties and planning permission too; we do not re-measure a N5 property for each submission.

Local landmarks that shape a Highbury application

• Tower Hill — frontages visible from the highway, so Angel materials detail governs the Tower Hill elevation.
• Highbury Square — terraced rear elevations — the Highbury Square party wall position is drawn first.
• Highbury New Park — frontages visible from the highway, so Angel materials detail governs the Highbury New Park elevation.
• Highbury Fields — proposals within its setting are drawn with the context elevation included.
• Emirates Stadium — Islington Council weighs N5 sightlines to it in the character assessment.
• Highbury Fields — proposals within its setting are drawn with the context elevation included.
