Retrospective planning application in Haringey
If you have built something in Haringey without permission, a retrospective planning application asks the council to grant it after the event. The borough granted 90.3 per cent of its 689 householder decisions in its latest year, so a carefully drawn as-built scheme is worth putting forward. Fixed quote after a free constraints check.

How we work on retrospective planning applications
Seven steps from first call to approval.

Enquiry and constraints check
We check the property against conservation areas, listed status, Article 4 directions, tree preservation orders, flood zone and planning history. We choose the right route and send a fixed quote.
Measured survey
We survey the house on one datum: rooms, levels, boundaries, drains, trees and the neighbours' windows that the 45° and 25° tests depend on.
Design options
We model the house in Revit and show you options in 3D and plan, with the planning strategy and the precedents in your street.
Design frozen
You choose an option in writing. Nothing changes after this without your say.
Independent check
A second chartered technologist checks every sheet against the council's validation checklist and the policy. A senior review signs it off before anything is submitted.
Submission
We prepare the forms, certificates, fee and documents and submit through the Planning Portal.
Officer liaison
We answer the planning officer and make any amendments within five working days, at no charge until approval.
Free redraws until approval. Every drawing set is checked independently, and the checker is never the person who drew it.

What Haringey expects from work that is already built
Haringey weighs a retrospective scheme against the Haringey Local Plan: Strategic Policies 2013-2026 (consolidated with 2017 alterations), with the Development Management DPD, Site Allocations DPD and Tottenham Area Action Plan, the same policies it would apply to a drawing submitted before building began. For extensions the guidance most often in play is the House extensions in South Tottenham SPD (revised), which shapes how rear and side additions are judged in South Tottenham.
That matters because a retrospective application has no second chance to be fixed on site. The council sees the building as it stands, so our drawings record it exactly: measured footprint, true eaves and ridge heights, window positions and the boundary relationship to each neighbour. We then test that record against the SPD wording before anything is filed.
Where the built work sits outside what the guidance supports, we say so early and look at what can change cheaply, such as obscure glazing, a lowered parapet or a trimmed depth, so the application you file is one the officer can recommend.

Conservation areas and Article 4 directions
Haringey publishes 33 named conservation areas and 25 Article 4 directions, mapped as 25 areas. Inside either, work that looked like permitted development when it was built may never have been lawful at all, and that is a common reason owners end up here.
The borough also has 289 Historic England list entries, of which 258 are Grade II. If your house or its curtilage is listed, planning permission is only part of the problem, because listed building consent is a separate matter that we flag during the free constraints check.
Knowing which designation applies decides the whole shape of the application, so it is the first thing we map for your address.
How Haringey has been deciding householder cases
The council decided 689 householder applications in its latest published year and granted 90.3 per cent, with 94.3 per cent decided inside 8 weeks or an agreed extension. Those are borough-wide figures for every householder project, not a forecast for yours.
Houses are the minority here: only 38.9 per cent of households live in a house or bungalow, so many retrospective cases involve converted flats, maisonettes and shared gardens where neighbours are close. We pay particular attention to the daylight and outlook of the adjoining flat, because that is where objections tend to come from.
Haringey also handled 396 lawful development certificate applications in the period, which shows how many owners test the permitted development route. If your work might in fact have been lawful, a lawful development certificate in Haringey may be the better first move.
Time limits, the fee and what follows
The enforcement clock for most unauthorised building works is now 10 years from substantial completion, so work finished several years ago is not automatically safe. The householder application fee is £548 and the council has 8 weeks to decide a non-major case.
If the council refuses, you have 12 weeks from the decision notice to appeal a householder case, and our planning appeals support in Haringey covers that step. Floorspace you added may also carry community infrastructure levy; the borough schedule gives £443.52/m² (Western zone); £276.16/m² (Central zone); £60.24/m² (Eastern zone), depending on zone.
One national policy line is worth knowing: Evidence that unauthorised development was intentional should be given substantial weight. An honest account of how the work came about is therefore part of the submission.
Evidence worth gathering before the survey
Start with dates. The council will want to know when the extension was finished, and a dated builder invoice, a bank transfer or a photograph with a visible timestamp settles the question faster than memory. If a previous owner built it, the sale particulars and the seller's information form often carry the clue.
Next, collect any earlier permissions for the property. Haringey keeps an online register, and a neighbour's consent for a similar extension next door can become a useful precedent that we cite on the drawings. Finally, tell us about any letter from the council. A notice changes the order of work, and we would rather know on the first call than discover it halfway through.
Drawings, price and related services
A retrospective set normally contains a measured survey of the building as built, existing and proposed plans, elevations, a section and the location and block plans. Our planning drawings in Haringey follow the same standard, and a second chartered technologist checks every sheet before it is issued.
Pricing is a fixed quote after the free constraints check, because the work to record varies from a shed to a full rear addition. For the wider picture, see architectural drawings in Haringey and the retrospective planning service overview. Neighbouring boroughs are covered too, including Hackney and Enfield.

Questions
Can Haringey refuse to look at a retrospective application?
Only in a narrow case: LPA may decline to determine an application covering matters in an enforcement notice issued before the application. Otherwise the council must decide it on its merits.
Is the South Tottenham guidance relevant to my house?
It applies to extensions in the area it covers. The House extensions in South Tottenham SPD (revised) is the document we check first when your address falls inside that area.
How long does the council take to decide?
The statutory period for a non-major case is 8 weeks, and Haringey decided 94.3 per cent of householder cases within 8 weeks or an agreed extension.
Does a retrospective application cost more than an ordinary one?
The council fee is the same householder fee of £548. Our own fee is a fixed quote because we first record the building as built.
