    Islington's urban design guide and basement guidance

    The council's design reference is the Islington Urban Design Guide SPD, which sets out how new work should respond to the street, the building line and the grain of the area. We read it for every address, because in Islington even a small rear addition is judged in terms of how it relates to the surrounding terrace.

    Basements get their own document, the Basement Development SPD. A project that digs down or lowers a floor attracts extra scrutiny. If your plan involves excavation, tell us early, and we pair the planning set with our basement impact assessments.

    Both documents operate under the Islington Local Plan: Strategic and Development Management Policies, Site Allocations, and Bunhill and Clerkenwell Area Action Plan, adopted in 2,023. Our drawings show how each proposal responds to the specific points an officer will test, using plain labels on the sheets.

    The practical effect is that every Islington sheet carries a short reasoned note beside each significant move: why the rear addition stops where it does, why the window pattern repeats the original and why the roof change is hidden from the road.

    Listed streets and conservation areas

    Historic England lists 1,050 entries in Islington, 12 at Grade I, 34 at Grade II* and the rest at Grade II. The borough also has 41 conservation areas and 33 entries on the Heritage at Risk Register.

    In a Georgian or Victorian terrace, many details are protected: front doors, sash windows, railings, ironwork and the roofline. We survey the front elevation as carefully as the rear, because a listed house needs consent for changes that would be minor anywhere else.

    We photograph the existing front, record its materials and show on the elevation exactly what stays. For a listed house the heritage statement is a separate document, and we can brief you on what it must contain.

    Flats, maisonettes and conversions

    With 26.7 per cent of households owning their home and few living in houses, many Islington clients are leaseholders or freeholders of converted buildings. Permitted development does not cover flats, so a householder application is the normal route.

    We note on the drawings which parts affect the structure or shared walls, since your freeholder or neighbour may need to give consent. A prior approval route is not open to flats, and a certificate applies mostly to whole houses.

    If you own the freehold of a whole building, you have more room. You may extend one flat, alter the building as a whole, or combine both, and the drawings and the form must state which. We settle that with you at the start, because a mistake here can invalidate the application.

    How Islington decides householder cases

    Islington decided 337 householder applications in its latest twelve months. It granted 92.6 per cent and decided 98.8 per cent within eight weeks or an agreed extension.

    These are borough averages. They suggest that a clear, well-argued householder case is dealt with quickly, but they say nothing certain about your house.

    Prompt decisions on well-prepared cases make a thorough first submission worth the effort. We check each set against the validation list, with location plan, scales, north point, ownership certificate and any heritage document in place.

    Price, checking and aftercare

    Our fee starts at £745, VAT included, and is fixed before you commit. The council's application fee, £548 for householder work, is paid to the council. A second chartered technologist checks every sheet before submission, and we redraw at no charge until approval if changes are requested.

    After consent, building regulations drawings in Islington turn the design into construction information.

    The process is short: address check, fixed quote, measured survey, options and a written choice, then a second-technologist check before we submit. Drawings normally follow the survey by about a week.

    If your freeholder needs to see the drawings first, we can issue them as a PDF for review before submission.

    Questions

    Which Islington guidance covers basements?

    The Basement Development SPD. Any project that excavates or lowers a floor should be read against it.

    Do I need planning permission for a flat extension in Islington?

    Usually yes. Householder permitted development does not cover flats, and a listed or conservation area address narrows the options further.

    How many listed buildings does Islington have?

    Historic England lists 1,050 entries in the borough. Listed building consent is needed for most changes to them.

    How much do planning drawings cost in Islington?

    From £745 including VAT, fixed up front. The council's fee is paid separately.
