House Extension Drawings in Harringay |

An Article 4 Direction applies across Haringey, so check it before assuming Harringay permitted development survives. The character of Harringay is the yardstick a Haringey Council officer measures a scheme against: Victorian terraced Ladder. Conservation status changes the Harringay route entirely — Highgate Village being the usual case among the 29 designations in Haringey. The Harringay boundary position decides how much can be done under permitted development.

The Harringay Article 4 position is established at survey, before design. Everything on a Harringay scheme is measured from the victorian terraces (harringay ladder) outward. The borough policy layer over every N4, N8 address is set out on Haringey planning. The Harringay survey then carries into loft conversion drawings in Harringay if the project runs on to construction.

One to two weeks at London Borough of Haringey before a Harringay case reaches an officer. A surveyor measures the Harringay property before any N4 design begins.

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.

We monitor the N4 case and respond to officer queries during the period. Nothing leaves for a Harringay address until it matches the local validation checklist.

On Harringay terraces the objection to expect is loss of light to a rear window. We measure the N4 property room by room, including ceiling heights and floor falls.

The party wall step is not optional on shared Harringay walls, and serving late is what stalls sites. Once consent is granted, architectural drawings follows for the N4 property.

Harringay is characterised by victorian terraces (harringay ladder), concentrated across N4, N8 in the Finsbury Park / Stroud Green area. Across N4, N8 the victorian terraces (harringay ladder) repeats often enough to be predictable, once it has been measured properly. Where Harringay 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. On a Harringay terrace it governs the rear opening width. The N4 terrace sets the datum; departures from it show up in the officer report.

Going down in Harringay is assessed on ordinary grounds — N4 ground conditions and drainage do more to shape the scheme than policy does. The Harringay measured survey is reused across planning permission for N4 properties and building regulations drawings, so the cost lands once.

Streets and landmarks we survey around Harringay

• Finsbury Park — front-to-back level changes that drive the Finsbury Park section drawings.
• Trafalgar Square — closet wings that change how a rear extension meets the Trafalgar Square back addition.
• Muswell Hill — gardens deep enough for the 8 weeks householder route on a Muswell Hill plot.
• Parkland Walk — gardens deep enough for the 8 weeks householder route on a Parkland Walk plot.
• Stroud Green — gardens deep enough for the 8 weeks householder route on a Stroud Green plot.
• Alexandra Park — terraced rear elevations — the Alexandra Park party wall position is drawn first.
• Chestnuts Park — shared flank walls, so Chestnuts Park party structure notices go out before work starts.
• Green Lanes — it anchors the Harringay streetscape argument in an officer report.
• Railway Fields — schemes in view of it attract closer officer scrutiny.
• Ducketts Common — massing on adjoining N4 plots is tested against it.
