    How we work on retrospective planning applications

    Seven steps from first call to approval.

    The same model cut through the middle: every floor, the stair, the chimney breasts, the new mansard, rear extension and basement in section
    Section through the model: every floor on one datum.
    1. 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.

    2. 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.

    3. 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.

    4. Design frozen

      You choose an option in writing. Nothing changes after this without your say.

    5. 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.

    6. Submission

      We prepare the forms, certificates, fee and documents and submit through the Planning Portal.

    7. 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.

    Havering policy and the two SPDs that apply to extensions

    The council decides under the Havering Local Plan 2016-2031, adopted in 2,021, supported by two documents we read for every retrospective case: the Residential Extensions and Alterations SPD and the Heritage SPD.

    The first governs how an addition should sit against the original house; the second comes into play near historic buildings and in the borough conservation areas. Together they set the questions we answer in our drawings: how far the extension projects, how it meets the roof, and what the materials say about the original building.

    Because the work exists, we measure it rather than estimate it. A surveyor error of a few centimetres can turn a borderline case into a clear breach on paper, so the as-built plan is the foundation of the whole submission.

    Green Belt in Havering and what it means for built work

    About 53 per cent of Havering is covered by Green Belt, which is more than half the borough. Your address decides whether you are inside it, so we check the boundary first.

    In the Green Belt the usual test is whether a building is a disproportionate addition to the original house, and whether it harms openness. An extension that looked modest at the planning-free stage may fail that test once measured against the house as it stood on the relevant date.

    We therefore draw the original footprint as well as the present one, with the percentage increase written on the sheet. Where a scheme goes beyond what policy accepts we say so honestly and discuss reducing the scheme rather than filing a weak application.

    Havering figures that matter to a retrospective case

    The council decided 985 householder applications in its latest year. It decided 97.8 per cent of them in time, which helps you plan once the application is validated.

    Residents also asked the council for 578 lawful development certificates, and 76.7 per cent of households live in a house or bungalow. For the larger prior approvals, Havering granted 21 and refused 27, so a deep rear extension built on the assumption of approval deserves a second look. A lawful development certificate in Havering may suit work that was actually within the rules.

    Fee, deadlines and levy

    The householder fee is £548 and the statutory decision period is 8 weeks. If the answer is a refusal, the appeal window for a householder case is 12 weeks, and our planning appeals support in Havering takes over from there.

    Havering is a levy borough with two zones: £151.52/m² (Zone A, North of A1306); £66.67/m² (Zone B, South of A1306). Mayoral charging sits in band 3, at £25 per square metre before indexation. Whether a given extension is liable depends on its floor area and on how the regulations treat unauthorised work, so we set out the likely position in the quote.

    Time also matters: the enforcement period for most building works is 10 years from substantial completion.

    Outbuildings, garages and the original house date

    Retrospective cases in Havering are not only extensions. Garden rooms, converted garages and large sheds can need permission too, even though owners often assume anything detached is exempt. In practice height, distance to the boundary and the size of the garden covered all count, and a building that breaks any one of them needs permission.

    The reference point for Green Belt and size tests is the house as it stood on a fixed date, so we trace its history using old plans, aerial photographs and the council register. Where earlier extensions were added by a previous owner, they count towards the total, and we show the running figure on the drawing.

    Keep receipts for the build, too. A paper trail showing who did the work, and when, helps if the council asks whether the building was ever lawful or whether a certificate could have covered it.

    What you get from us

    Questions

    Is my Havering extension in the Green Belt?

    Possibly: 53 per cent of the borough is. We check your address on the free constraints check, before any fee.

    Which Havering documents will the officer use?

    The Residential Extensions and Alterations SPD and, near historic buildings, the Heritage SPD, alongside the Havering Local Plan 2016-2031.

    What happens if the council already wrote to me about the work?

    Tell us at once. The law says LPA may decline to determine an application covering matters in an enforcement notice issued before the application, which can affect timing.

    How many householder cases does Havering grant?

    85.9 per cent of 985 decisions in the latest year. That is an average across all householder work.
