Planning consultant in Wandsworth

Wandsworth decided 902 minor applications in its latest year, nearly as many as its 977 householder cases, which tells you how much of the work here is conversions and small developments. A planning consultant helps most on exactly those. We advise on Wandsworth homes on a fixed quote after a free constraints check, with MCIAT chartered architectural technologists drawing the scheme.

    How we work on planning consultant

    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.

    The plan and the one guide that covers everything

    The development plan is the Wandsworth Local Plan 2023-2038. The document for home alterations is the Housing SPD (covers rear extensions, basements, roof extensions and loft conversions), with the separate Basement extensions guidance (non-statutory) sitting alongside it.

    One guide for many project types means one checklist, and officers know it well. A consultant reads it against your scheme and notes where the design leans on a tolerance rather than a rule.

    Wandsworth has no Article 4 direction for houses in multiple occupation, so a shared-house plan is judged on ordinary planning merits.

    A borough of flats, conversions and conservation areas

    Only 31.4 per cent of households live in a house, so flats dominate. Flats lose householder permitted development, and many alterations need a full application.

    The council publishes 46 conservation areas and Historic England lists 312 entries, with 8 on the Heritage at Risk register. Inside those areas, design detail draws closer scrutiny.

    Basement schemes are a distinct Wandsworth topic, because the council keeps non-statutory basement guidance beside the main housing guide. We flag early whether a lower-ground scheme is likely to meet it.

    How decisions fall in Wandsworth

    The council decided 977 householder applications in the latest twelve months, granting 91.9 per cent and deciding 92.4 per cent in time.

    Minor applications numbered 902, with 86.7 per cent granted and 88.1 per cent decided in time. Those are strong rates for a volume that large.

    The numbers describe the borough. Your own scheme is judged on its own facts, and a consultant is there to identify those facts early.

    Planning consultant in Wandsworth: what we do with your address

    We read the designations, the history on the plot and the neighbours, and check whether the property is a flat or a house, because that decides which rights remain.

    You then get a written view of the route, the one or two policies that will decide the outcome and the documents the council will want. Where a basement or roof extension is involved, we say whether it fits the guidance before you commit to design fees.

    Drawings and statement are prepared together, checked by a second chartered technologist, and submitted with the fee. We deal with the officer through to a decision.

    What a Wandsworth statement has to cover

    The housing guide is detailed, so the statement tends to follow its structure. For a rear extension that means depth, height and the effect on the neighbours; for a roof alteration it means the roofline of the terrace and the visibility from the street.

    In a conservation area we add a short heritage assessment. In a flat conversion we address amenity, refuse and cycle storage, and in a basement scheme we deal with structure and drainage early, since officers raise both.

    Every statement we write is checked against the sheets by a second chartered technologist, so a depth or height in the text always matches the drawing.

    We also keep the neighbours in view. A short, courteous conversation with the people either side before submission often reduces objections, and where a party wall notice will be needed we explain it in plain terms and in the right order. Those steps do not change the policy test, but they can change how the officer reads the file.

    Levy and fees

    The borough levy varies sharply by area, from £1,031.39/m² (Nine Elms Residential Area A); £475.34/m² (Nine Elms Residential Area B); £0 (Roehampton Charging Area); £448.43/m² (all other areas). Only certain parts of the borough attract the highest rates, so the location of the site decides the charge.

    The householder application fee is £548. We confirm the fee and the validation list before submission, so the file is complete on the day it arrives.

    The council publishes 46 conservation areas, and 312 listed entries lie inside the borough.

    What share of Wandsworth householder applications are granted?

    91.9 per cent of 977 decisions in the latest twelve months. We make no promise about any one scheme.

    What does a Wandsworth planning consultant cost?

    A fixed quote after a free constraints check. The council fee is separate, at £548 for a householder application.
